About this trimaran, Rast... i think it too brad and large, width about15-20 meters. I was hoping these ***marans will be able to sail amongs city channel-streets... For this use it got to be more strait then from this foto... Anyway, it can used for sea sailing
Ok, let's sum up the ideaAs we are working on the city. We should focus on boats
especially made for city-life- We either need small boats or we can use promes connected with vines easily maneuvering the city. If you're pretty unskilled you'll sooner or later bump into the canal walls so some kind of bump-shield or tougher materials, maybe even repellant rubber matierials. Sails are no problem. Currently our boats are so small it'll easily fit under a bridge.We could use rast's "wind glyph" idea and elevate the ships a couple of meters above the city streets. That would give room for bigger ships (and an option to "flee" the floating island

) Also, the farther in you come into the city the shallower the
reef is, we will need to use a material or a new model to enable other ships then katamarans to sail the city channels. We will have to make our own laws because if you're a fishing race you will surely take your boat to work

That will need attention.
So for future use:
--->Small boats or trains of connected boats, maybe even floating boats
--->Resistant materials on sides and keel
--->Laws for sailing in City.
@Laragorn: Good point, we wont need huts other then on longer voyages.
