If it is an Eastporter I would say it is very rare. Not many of these boats were built with a keel/inboard in the 20' range- but maybe it is. There was an Eastporter for sale recently that had an IB/OB.
Haha it would that would be fun. Except they have us working on wooden skiffs in boatbuilding class? The chances of any of us working on a wooden boat are slim to none. Makes no sense to me. I should talk them into buying both!
