It's worth something to somebody. I have a 40-year old wood framed Pouch (Klepper's East German competition) that we had a ton of fun with, but it doesn't fit the family needs now and I doubt it will ever be the "go to boat" again. It takes 30 min to set up and can go on the gear pile in the back of my Otter 150 and it can fly with us on a commercial carrier to Mexico or Hawaii. I can see some more fun in its future when our girls are a little older.
List your boat on a sea kayaker forum, see what it's worth to someone, then decide what it's worth to you and the fam.
