In comparison to other dinghies, these prices were extremely high. The product quality seems to have justified such prices but surely it made marketing more difficult. The truth is that a Top Notch boat can fetch quite a bit more, especially if it comes with the original Handbook and without bottom paint. Harpoons seem to have held on to their value remarkably well. Boats in top shape usually sell very quickly.
Potential buyers have to be willing to act quickly.
In principle, dinghies which are still being made and which enjoy active racing fleets will command comparatively higher prices. The actual asking price will very much vary to local supply and demand. Obviously, boats that require some work will fetch less. On the other hand, there is not much that a qualified boat yard could not fix on a Harpoon. Originally, Harpoons were popular in the Southern Ohio area and in many parts of Texas.
