$34.00 - $405.00


This launch was designed for easy trailing so a length of 23' with a moderate beam of just under 6' were set. In line with the Simson Strickland style of launch, the stem and transom are fairly plumb with a deep forefoot giving hollow lines forward and maximum effective waterline length for speed. The midship section is fairly full with a wide waterline beam to give good form stability and above the waterline, the topsides are well flaired forward to deflect spray and run into tumblehome aft giving her a shapely transom.

The saloon unusually, runs from the forward coaming and covers just over half of the cockpit to give maximum protection in choppy conditions to both crew and steam plant. Steering is by a side wheel adjacent to the engine . The aft part of the long cockpit is covered by a canvas canopy and she can sit 6 to 8 people comfortably. The internal fit-out can be changed if a long cockpit is not required. Construction is Cedar Strip.

Note - the plans also include details of a more plumb stem.
