This won't sound kind, but I think the Herreshoff name attached to the catboats, sloops, Scouts and Harbor Pilots is overly emphasized. Halsey Herreshoff designed it, of course, and it may be related to an earlier Herreshoff half model but it's essentially a catboat hull in different arrangements. Marshall Marine pretty much dominates the market in the line of small catboats. The Pilot is a yet more specialized boat and therefore in an even thinner market. But your boat is well restored and is just waiting for someone who wans an open harbor cruiser of the type.
