  • Hull type: Semi-displacement twin pontoons with deck unit. Developed for 1/4" and 3/8" sheet plywood planking, 5/8" for deck. All members framed in solid wood.
  • Power: Most practical with single outboard centrally mounted. Anti-cavitation deflector to be installed under deck unit forward of motors (details for construction provided). Horsepower should not exceed recommendations. Twin outboards may be used, preferably with outboard transom mounting brackets aft of each pontoon, with sufficient bracing provided on the transom (details not included). Long shaft motors recommended.
  • Can the hull be extended or shortened? No, not beyond the range listed. The same set of plans details all sizes. We do not recommend increasing the beam.
  • Trailer: Designed for use with Glen-L HUCK FINN boat trailer plans.

Note: The HUCK FINN Plans & Patterns do not include the plans for the "Sportscraft" or "Huck Finn Cabins". These units must be ordered separately.
