As for me i'm against enchanting all in all.
Enchanting boat to move it without any nature force, enchanting backpack to make it bottomless, enchanting spoon to make it stainless, enchanting bootlace to make it self-tying... I think it's very simple and ordinary to put magic everywhere where we still can't find more interesting design. If we continue so, the soon we "invent" automotive carts (car), automotive boats (motor boat), self-flying vessel (plane)-->and where to our fantasy medieval world come?
I think, magic - is an energy, and it has it magic physical principles. PlaneShift isn't a fairy tale where we could say "Abrakadabra" and in our hands appeared super-lazer jedy-sword. So, piscatorial boat is a just piscatorial boat, imho. Klyros are famous fishermen because their physical skill and not for their extraordinary magic skills.
Add to your model Sail, oars, etc. Make middle hul longer and, try to apply to whole model bird's wings silhouette... You have such good and well-detailed reference, Rast, try to modify it in klyros style.
The lesser width for street - 2m, the middle - 4+2m, the widest 8-+2m.
I think in-game we will not be able to travel by boats/gondolas/katamarans (for this moment, though), but... we got to model this stuff, cause... what it will be a sea-shore city-port whithout any ships? :O
..Hmm, my older brover coming, got to drink with him some magic vodka...Disconnected.
