Kit price and free labor are the most likely to succeed. You need  exceptional customers and boats to do better than that. Sometimes it happens, though. On the other hand, I've seen your boat and it is one of the exceptional ones. You won't have any trouble justifying a workmanship premium to a serious customer.

Careful with brokers, though. They expect a certain return on their time (that's reasonable) so they may have to charge a larger fee than you want to pay for selling a single person boat. In other words, they're the broker, you're the brokee.

And remember, if it all gets too much there's the donation route. Many maritime museums accept donated boats which they resell. The museum gets some money and you get a tax deduction (though with the new standard deduction it's not as good as it used to be) and the joy of having supported a worthy organization.

Good luck,
