   * Ship Types, Classes and Purposes

          The world of ships and boats is wide and diverse enough that
     there are countless number of ship types and sizes.  But here is a
     brief overview of the most common ship types and their descriptions.
     The information is in no particular order of importance or history. 

      1. Logboat - A thick log, often oak, hollowed out creating a long
         narrow canoe.  These were often thin-walled, crude, rough and
         heavy.  These craft become less of a value when planked boats
         were used. Often also called dugouts or monoxylon.  These are
         man powered boats. Usually these craft are used within sight
         of land. 

         Material - Wood/Single Log Usually
         People   - 1 person usually some large ones can do 1-2 more
         Length   - 4-10 feet depending on log cut
         Width    - 2-3 feet wide
         Type     - Boat

      2. Barge - Barges are flat-bottomed boats that are mainly used in
         rivers for cargo transport of heavy goods.  Most barges have to
         be pushed by towboats or pulled by tugboats from place to place.
         There are several types of barges used.  Barrack barges have
         living quarters on them.  Dry bulk cargo barges haul rock, grain,
         etc.  Liquid cargo barges for liquids like water or oil.  Royal
         barge for ceremonial purposes. Another type is commonly called
         a lighter, as such those who move barges are known as lightermen.
         Generally barges are slow, basically a platform and built to
         hold a lot of tonnage.  Animal barges carry animals (like
         cattle, horses or elephants in war) where they are placed in
         a fenced/boxed in area.  The Battle Barge was made for combat
         and not to carry cargo.  it would carry men and/or animals.
         Some of these battle barges may have been made with shipboard
         weapons.  
            A earth example is that of the Egyptian barge - which were
         made to carry large stones.  These were 200 x 30 feet in size
         and took 30 oared tugships to move the barge.  

         Material - Wood
         Length   - 100-200 feet
         Width    - 10-30 feet 
         Type     - Boat 

      3. Canoe - Boat typically pointed on both ends with a hollowed
         out area where a person sits.  Construction materials would
         include a simple hollow log, wood or canvas construction.  It
         is powered by paddles.  The number of paddles depend on the
         number of people.  The person would use the paddles kneeling,
         seated or on supports on the hull.  They face the direction
         they are going in (unlike rowing).  The paddles can be single
         or double bladed paddles.  

         Material - Wood, Canvas, Birch bark, tar and/or tree sap
         People   - Usually just 1 sometimes 2
         Length   - Varies, 6-8 feet usually
         Width    - 3-4 feet typically
         Type     - Boat 

      4. Catamaran - This craft consists of two hulls joined by a frame.
         They can be man or sail powered.  Catamaran name means "logs
         bound together".  Many can be ocean going ships allowing them
         to sail great distances.  This craft is known to have problems
         turning against the wind (tack) due to its design.  They tend
         to have a higher average speed than monohulls. They are faster
         due to no keel counterweight.  They are good for coastal
         cruising and as a long distance boat.  These typically weigh
         around 165 pounds. 

         Material - Wood
         Length   - 10-25 feet
         Width    - 15-20 feet typically
         Type     - Boat or Ship

      5. Coracle - This is a light boat, oval in shape and formed of
         canvas stretched on a framework of split and interwoven rods,
         and well coated with tar and pitch to render it water tight.
         The framework was typically covered with horse or bullock hide
         (corium). These ships are so light and portable it can be
         carried from place to place.

         Material - Wood/Hides
         Length   - 3-5 feet
         Width    - 3-5 feet 
         Type     - Boat 

      6. Cutter - These are any sailing vessel with two or more head
         sails and a mast which is set further aft than that of a sloop.  

         Material - Wood
         Length   - 12-18 feet
         Width    - 4-9 feet 
         Type     - Boat 

      7. Dhow - Sailing vessel with one or more triangular sails
         (lateens).  There are several types of dhows typically used.
         Shanjah a large vessel with a carved stem and a sloping,
         ornately carved transom.  Baghlah is the traditional deep
         sea dhow.  Battii featured long stems topped by large,
         club-shaped stem heads.  Badan were smaller requiring a
         shallow draught.  

         Material - Wood
         People   - 12-30 Crew
         Length   - 6-50 feet
         Width    - 6-15 feet 
         Type     - Boat 

      8. Dinghy - This is a small utility boat used to tend a larger boat.
         While they serve specific purposes they can also be used as
         leisure craft.  Larger forms of dinghies are lifeboats which
         can carry a full family and a month's worth of supplies if needed.  

         Material - Wood
         Length   - 6-18 feet
         Width    - 4-12 feet 
         Type     - Boat 

      9. Dory - This is a shallow draft boat which are lightweight and
         versatile.  These are typically used in the open sea for
         commercial fishing operations.  The hullform is characterized
         by flat sides angled close to 30 degrees from the vertical, and
         a bottom that is transverely flat and arced fore-and-aft.
         These were typically carried by larger fishing boats then
         deployed to lay down longlines or fishing nets.

         Material - Wood
         People   - Typically 2-4 including the oarsman
         Length   - 15-22 feet
         Width    - 5-7 feet 
         Type     - Boat 

     10. Ferry - These are boats or ships that carry passengers and
         sometimes their vehicles in short-distance, regular scheduled
         services.  

         Material - Wood
         Length   - Varies, no standard size
         Width    - Varies, no standard size
         Type     - Boat or ship

     11. Junk - Classic Chinese sailing vessel. High-sterned, with
         projecting bow, the junk carries up to five masts on which are
         set square sails consisting of panels of linen or matting
         flattened by bamboo strips. Each sail can be spread or closed at
         a pull, like a venetian blind.  Junks are efficient and sturdy
         ships that can travel the oceans  The hull had water tight
         compartments accessed by separate hatches and ladders.  The
         purpose of the junk usually determined the size of the ship.
            Treasure Ships - (9 masts), 400 feet long, 160 feet wide
            Horse Ships - (8 masts), 339 feet long, 139 feet wide

            Troop Ships - (6 masts), 220 feet long, 83 feet wide
            Patrol ships- (8 masts), 120 feet long
         Water tanker junks could carry 1 month of fresh water for
         re-supply of other ships or forces.

         Material - Wood and teak (tropical hardwood trees)
         Length   - 100-450 feet
         Width    -  50-160 feet
         Type     - Boat or ship

     12. Kayak - A small human powered boat.  The person uses a double
         ended paddle.  The person sits in the middle with feet forward.
         The top has a covered deck.

         Material - Wood 
         Length   - 5-7.5 feet
         Width    - 2-3 feet
         Type     - Boat 

     13. Ketch - This is a sailing craft with 2 masts.  The main mast
         and a mizzen mast abaft the main mast.  Both are rigged mainly
         fore and aft.  

         Material - Wood 
         Length   - Varies
         Width    - Varies
         Type     - Boat 

     14. Lifeboat - A boat carried on board a ship and designed to allow
         passengers to escape, or a boat kept on land to rescue people
         in trouble at sea.  

         Material - Wood 
         Length   - Varies, 3-15 feet
         Width    - Varies, 3-12 feet
         Type     - Boat 

     15. Rafts - This is a special type of boat, distinguished by the
         absence of a hull.  They are kept afloat by naturally buoyant
         materials like such as wood, or by inflated containers.  Rafts
         were the earliest known water craft.  From logs to Keleks.
         A kelek was a floating raft of bladders & leather.  A typical
         Kelek was 50 feet wide with up to 1,000 bladders.  The Kelek was
         a wooden platform of planks or logs that had air bladders (skin
         or animal parts) made usually of leather materials all tied
         together.  Hanibal used a Kelek for war elephants which was
         100x50 feet in size.  Another common raft was that of the Pot
         Raft.  These were rafts that used hardened ceramic pots for
         ballast or to float when filled with air instead of bladders.

         Material - Wood, Bladders/Pots
         Length   - Varies, 5-100 feet
         Width    - Varies, 5-100 feet
         Type     - Boat 

     16. Tugs - Tugs are typically ships powered by rowers.  But some
         could be used with sails depending on the number of tugs and
         the load to pull.  These ships are used to pull or push a ship
         from place to place.   The port/harbor tug are smaller and tend
         to help navigate other ships into ports to avoid reefs and
         heavy traffic areas.

         Material - Wood
         Length   - Varies
         Width    - Varies
         Type     - Boat or Ship

     17. Merchants - Merchant class ships are as wide and diverse as
         civilian craft.  There have been thousands of various types
         and sizes of these ships.  Merchant ships are the backbone to
         most economies for national income.  They help to promote trade
         and growth.  They carry cargo, animals or people from place to
         place.
           Roman merchants had masts that carried square sails.  Steered
         by two side rudders connected to each other.  The largest known
         roman ship was 95 meters long.  
           Caravels were classic Spanish and Portuguese merchant ships.
         Cogs were sturdy one-masted merchant ships with a flat bottom.
         The Etruscan merchant ship was 20 meters long.
           Merchants are also commonly called freighters, traders, haulers,
         transports and cargo transports.  How much a merchant could
         carry would depend on the ship but on the average it was 450
         tons of cargo.  In one ship wreck a keel of a merchant was known
         to be 17 meters long.
           The smallest cargo ships were only 70-80 tons while 350-500
         tons was large ships.  The largest grain freighter on record
         was 1700-1900 tons they estimate of a ancient merchant.  Some
         large merchants could carry up to 600 passengers.  A typical
         large freighter in ancient times, a 1,300 tonnage cargo ship
         was 180x45x43.5' in size.
           Merchant cargo ships could typically sail at 5 knots.  But
         waited for a good wind.  If not they would have to sail in
         a zigzag pattern, to get the wind, which took them twice as long.
         Merchants typically had 1 or 2 masts.
           The Corrack was also a name of a type of merchant ship. 

         Material - Wood
         Length   - Varies, 60-100 feet on average 
         Width    - Varies, 25-35 feet on average
         Tonnage  - Varies, 50-500 on average
         Type     - Ship 

     18. Skin Boat - The Skin boat was one of the earliest type of craft.
         It had a skin tied around a wooden frame.  

         Material - Wood, Skins
         Length   - Varies
         Width    - Varies
         Type     - Boat 

     19. Galley - These were warships that were rowed or sailed by
         triangular lanteen sails to the battlefield.  Homer tells
         of the classic galley being low and open.  The superstructure
         complex with "horns", sleek & fast, rowers and the sail can
         be lowered or raised.  Typically a galley cost 10,000 gold to
         build one that was 50 feet long.  Whereas a Galleon cost 210-
         250x that of a War Galley.  The typical galley had 20 rowers
         for quick dispatch. 

         Material - Wood
         Length   - Varies, usually 60-90 feet long
         Width    - Varies
         Type     - Boat 

     20. Brig - This is a 2 masted sailing ship where both masts are square
         rigged.  The rear mast carries a gaff sail as well.  

         Material - Wood
         Length   - Varies
         Width    - Varies
         Type     - Boat or Ship

     21. Penteconter - This ship was more durable than the standard trireme
         and less expensive.  It had more room for supplies and less crew.
         It was good for war and trading.  This ship had 50 rowing places.

         Material - Wood
         Length   - Varies
         Width    - Varies
         Type     - Boat or Ship

     22. Quadreme -  Another type of warship.  this ship was typically
         found with 2 men for a catapult, 6 archers and 19 marines.
         It had 4 oarsmen per oar which only needed 2 of them to be
         skilled in rowing.  

         Material - Wood
         Length   - Varies
         Width    - Varies
         Type     - Boat or Ship

     23. Longboat/Longship - These ships were long as their name implies.
         They served many purposes from war to transport.  They had 15
         foot masts.  The ship weighed about 20,540 but empty about 5,300
         pounds.  It had 24 oarsmen.  We know it had 115 square feet of
         sail cloth for its sails.  It was rather advanced since it had
         Bilge pumps.  It only had a crew of 16.  It could handle 15
         square feet of cargo space with a typical load of 3,950 pounds.
         It had a volume of 205.3 cubic feet of space.  It could reach
         a speed of 7 mph.

         Material - Wood
         Length   - Varies
         Width    - Varies
         Type     - Boat or Ship

     24. Trireme -  The Trireme was the standard warship in the ancient
         world.  It was a very quick narrow war galley.  It used sails
         for transportation but oars for battle.  As the name implies
         it had 3 rows of rowers on each side.  It was a upgraded version
         of the bireme.  They could attain speeds slightly over 10 knots.
         They could chase and then sink a ship with its ram.  The hull
         was made from light pine tree wood.  In good weather they could
         even get up to 14 knots.  These had one tier of rowers, 1 person
         per oar, with 25 on each side.
           In the battle of Salamis 300 Greek ships (half triremes)
         defeated 600 Persian ships.  The entire Salamis Campaign saw
         action with over 3,000 ships with an average ship of 4 tons.
         On average the ships had 50 oarsmen and 90 others as crew.
           A Trireme could disable or sink a ship.  This was done through
         a tactical maneuver called diekplous, or in English "break
         through and ram."  They would line up in a square formation.
         Some would quickly turn and ram into opposing ships.  The ram
         or beak of the ship was covered in heavy bronze beaks.
           One major drawback was that the Trireme was light and often
         blown off course when high winds arose.  Because of this
         quinqueremes were developed.  These had 3-4 tiers of oars with
         2 men to an oar.  This made it more heavy and less prone to
         being flown off course.  0
           The Trireme was steered by a pair of heavy, broad-bladed oars.
         They were used by one man each.  The sail was lowered and raised
         according to the rain.  When the wind was light the sail was
         fully extended. When the wind became gusty and strong the sail
         would be lowered. In severe wind and storms the sails would be
         lowered completely for fear that the ship might be blown over.
         First anchors were a single large stone.  Later they were made
         into 2 armed wood and lead anchors like we use today.
           A trireme only carried enough supplies for 2 days.  They were
         expensive to build, man, supply and function in high seas. The
         ship would beach at night since it was more fragile for water
         anchoring at night.  These ships would typically only last 20
         years.  
           There were several types of Triremes.  the Fast Trireme was
         made for speed.  Troop Triremes could carry 40 men not just
         the standard 10 the standard trireme carried as marines.
         There were 1st, 2nd and 3rd generation Triremes depending
         on wood, hull design and age of the ship.  Horse carriers were
         modified to carry 30 horses and only had 60 oarsmen.  The food
         for the crew only lasted 1-2 days and was porridge and a handful
         of figs for each person.
           The Trireme had many rowers in 3 banks.  Each bank was at
         sea level, below the water and at the rear outrigger.  Each
         bank was on top of the one below it. The name of the banks -
         Thranite, Zygite, Thalanit Rowers (top to bottom).  There were 27
         in each bank slightly ajar with 4 aft making 170 oarsmen total.

     11. Trelen (like Trireme) - Ship could make 8 knots top speed and
         4 cruising giving an overall range of 6-12.  It has a crew of
         170 rowers (31 to a side in the uppermost position, 27 in each
         of the other 2 bank levels.  They would have roughly 12-16 marines.
         They had 5 officers including those listed in #12 below.  

     12. Crew positions: Captain was usually a political appointee,
         Helmsman, Timbermaster, pentekontarchos (paymaster, purchasing &
         recruiting officer), Bow Officer (foredeck lookout), Flutist,
         Deckhands to manage the sails, Ship's carpenter, Quartermaster
         (did steering sometimes) and sometimes a ship's doctor.

     13. Rowers were typically paid a drachma a day.

     14. Other Classes of ships to consider for design:

         A. Yachts.  These are pleasure craft that tend to be long and
            luxurious though expensive to build.  Most are river but
            some are sea-worthy.  Many are designed with elaborate
            cabins for passengers.

         B. Fishing Boats: Fishing boats are short range ships that
            are built for the purpose of fishing.  They have large
            holds to hold their captures.  They have elaborate nets and
            fishing line setups.

         C. Couriers: These ships of any type tend to be made for nothing
            but speed.  They are messenger ships that have no passengers
            than what is vital.  They are made usually for long range
            and fast speed.

         D. Exploration: Exploration ships depend on the nation that needs
            to explore.  These tend to be slow but built for long range
            trips to map out entire areas of the ocean.

         E. Medical Ships: Though not common in ancient times it is possible
            that a nation has a medical ship for its battle fleets.  These
            ships have healers (with possible healing magics) to help
            take care of wounded men.  This is a non-combant ship.

         F. Surveillance/Recon: Many ships had fast moving ships that were
            made to recon an area or spy on enemy ships and fleets. These
            were built for speed not combat.  They tended to have skilled
            crews specially selected for recon duties.

         G. Escorts: Many non-combat ships had escort ships.  Typically
            Escorts were combat oriented ships from simple barges to
            full Triremes to guard convoys like merchant ships.

         H. Frigates: Frigates were typically designed to carry troops
            for ship-boarding operations.  In ancient times though
            Frigates weren't a popular concept.

         I. Patrol Craft: There are typically two types of patrol craft.
            River and Ocean patrol boats.  These patrolled the areas for
            enemy ships or trouble for the nation they worked for.  These
            were typically armed with ship board weapons rather than ram
            weapons.

         J. Passenger Liner: When a ship design needs to be determined
            the captain should decide if it will carry passengers or not.
            Ancient times had no big passenger liners like in modern times
            but ships should consider passenger cabins and space.

         K. Raiders: Raiders were fast moving ships like pirate boats.
            They were made for hit and run tactics.  They would attack
            ships or towns on the coast with lightning speed and tactics.

         L. Scout:  Battle fleets had many scout ships.  These were like
            recon ships.  Scouts typically led forces early into battle
            to test the enemy strength or determine if the enemy had
            weak spots to take advantage of.

         M. Tenders:  An advanced term but repair ships could be considered
            as well.  These ships could contain everything needed to fix
            ships away from ports.  They could carry spare wood and other
            supplies to patch hulls.  They could carry skilled craftsmen
            to repair other aspect of ship damages.
