Construction Sequence
Zipper is an 11 foot runabout based on designs of the 1950's for Class 'B' stock utility racing boats by Hal Kelly and William Jackson.
This design differs from those of the period in that it is to be constructed in the 'Instant Boat' method using glass fiber and polyester or epoxy resins to make the joints.
10hp should be sufficient to see her planing at over 30 mph.
