OK, I have finished my Peterborough Cedar Rib and have the sail kit for her. I took her out for our maiden sail on a wide section of the Great Ouse near home so that we could get acquainted with each other. The canoe came with a slatted seat which I propped up against the centre thwart (which in fact is just back from the centre). This made me slightly bow heavy as you can see from the photos; part of this is down to my mass. I am off on a canoe sailing weekend soon and need to add some flotation as we will be out on a large expanse of water in the Norfolk Broads and I need something just in case. I have long pillow air bags which I will strap along the sides and beneath the front and centre thwart but this leaves little room for me between them. Should I be kneeling behind the centre thwart? I expect it will be trial and error.
