What I need: It should a medium or small ship, (crewed by about six to nineish, if possible), more for shorehopping than anything else; it should be capable of bringing small amounts of cargo, but I could get along with "this isn't a cargo ship, I dunno what you're thinking." Time period is mid/late eighteenth century. Speed is good, but it should be one that's easy to maneuver - this is more important than speed, ultimately.
The simpler, the better. I know a very little of sails and rigging, and I don't want to have to BS too much of it (if there's a site with nice pretty drawings explaining things in layman's terms, I'd be glad to see it).
Direct Questions: Can I, instead of cannon, have smallish ballistae for my missile weapons? (I know it's cannon do damage to other ships, but it's not other ships I'm looking to do damage to.)
Food? Food storage? There'll be a number of journeys into cold climate - anything different about storage then? (Also, what about the IM IN UR BASE, EATIN UR FOODZ problem: do insects & animals living in/off said food die in said cold climates? Will we have supercooled rats?)
Anything else you can think of I forgot, I'd appreciate. Thanks in advance!
