I have a clamp-on boat seat that I'm looking to get rid of, since I have two and rarely use both of them. You can use it when rowing, though it is easier to row when using the seat on a 14' rowboat than a 12' rowboat. It is definitely more comfortable than using a seat cushion, and is handy if you sometimes use a trolling motor and sometimes use oars. This item doesn't appear to be available in BPS's catalog. If anybody is interested in this item, I'd be willing to sell it for $10, not including shipping.
