James Wharram is a man who really loves boats! He designs and builds his own boats in a way that is very special and unique.
You know how sometimes you see a big boat with a pointy front and a flat back? That's called a "monohull" boat. But James likes to build "multihull" boats, which means they have more than one hull - two or three, in fact! And instead of being pointy at the front and flat at the back, they are kind of like two or three canoes stuck together side-by-side.
James also likes to use a kind of special sail called a "square sail," which is different from the triangle-shaped sails you might see on most boats. Square sails are really big and flat, like a big sheet hanging up in the wind.
James thinks that his boats work better than other boats in a lot of ways. For one, they can go really fast because they're very lightweight. And because they have multiple hulls, they don't tip over in the wind or waves like a monohull boat can.
Overall, James Wharram is a really cool guy who has a lot of fun designing and building boats that are different from what other people make.
