Hi Allen, I have a Zippkit Springer as you can see from my picture. It was simple to make and works well. Only suggestion I have is get the single motor version. My friend bought the twin motor version at the same time and it is overpowered. John.
I have spoken to the person who built the boat. It is based on a Vintage model boat company design. It was scratch built and is made of strips of mahogany as I originally suspected. Having looked at the Vintage model company site it most resembles a sea hornet, however another kit may have been available at the time it was made. The strips of Mahogany were the builder making use of the materials they had to hand at the time, hence the vertical strips! The interior is covered in fine fibreglass mesh and 3 thin coats of fibreglass resin. Work on the restoration continues!
