I'm selling a solid, self-built CLC kayak converted to a sailing vessel using a CLC kit I purchased in the 90s. Two dagger boards added, deep rudder. I've posted a photo on my site. Super fun to sail - but you'll want gloves, bc the sail tends to rake over your knuckles when you come about. Kayak is 19 feet long, pontoons can carry weight of small children, sitting or standing and fishing. $3K OBO.
