So I'm writing a book that takes place in an endless ocean with islands inhabited by many races, and I'm trying to come up with unique boat ideas for races; well I have most of them, but I would like some help with one race.
I call them the Cellene, they have a body shape like most humans but their legs and arms are 25% longer, and most reach a height of 8 feet, the tallest being 10 feet.
I don't think boats as we build would work for them so any ideas would be helpful.
EDIT: To clear up some things these people only have up to probably the tech that they had around the time of the Roman Empire, and they also live on islands, they wouldn't want to waste wood resources on making larger boats they would make different ships to fit their needs. They are tall, but not all that strongly about the same as an average human. Also, they would be travelling about 350-500 miles per trip between the main islands they live on and much longer for trips out to the islands beyond the center 3
Edit 2: Raditz did clear up some things for me, the real question is I want to have a boat using the same amount of wood, relative storage space and convenience of travel (since this is the only method of travel between islands other then swimming) but just for larger kind of oddly shaped humans.
