Appreciate your interest in these, Art.Unreliable memory says Halvorsen made 25,26,30 and 38ft for the hire fleet. Not sure about a 40 but it`s possible. They built 36s, but usually with flybridge, there`s one on my marina, recovered after it took a swim. They built all kinds of boats to order, a prolific builder, not just for their hire fleet.
A pretty 26 just came on the market. The preservation of original features never ceases to amaze me. Originally most had single gas engines, often Chryslers, prone to flooding at start up for the unwary. Many of the boats are ex hire fleet, well maintained for hire/charter, which sold off went to good homes.
