This is a weekly posting with GURPS vehicles (and the like) to the
GURPSnet mailing list. I grant the permission for all non-commercial
redistribution of my work, but I would like to know if you put it on
a website or the like. With a slight delay, old vehicles appear

Caravel of the Line v1.0 (TL3)
Copyright 2005 by Onno Meyer
Any experienced time traveler should know how to make gunpowder, but
designing the rigging for a proper ship of the line or casting tons of
bronze for a large cannon are more difficult.
So this ship uses a lateen rig much like a 15th century caravel. The
lateen rig had been used for small boats since Roman times. The cannon
are all rather short, with two 24-pounders, eight 12-pounders, and two
6-pounders in each broadside and two 6-pounders in the bow.
It takes 30 men to sail the caravel and 200 to fight it with gunners
for one broadside and a few marines. There is room for 200 hammocks in
the gun deck and a comfortable cabin aft. Four more cabins have solid
locks for important prisoners: it would never do to toss them into the
dark and damp hold.
As listed, the caravel carries 120 tons of food and water, 54.8 tons
of guns and ammunition, 40 tons of cargo and 1.5 tons of boats on deck.
Subassemblies: Body +8, Superstructure +5, 100' Mast +2, 120' Mast +3,
90' Mast +2, Open Mount +1.
Powertrain: 11,000 sf lateen-rigged sails.
Occ: 25 RCS (body), 4 RCS (superstructure), 2 XCSR (OM), 200 hammocks
(body), 1 luxury cabin (superstructure).
