Mk III Push-boat/Harbor Tug

25'6" Hull Length     16' Beam

Draft 5'5"     Disp; 64,000lbs

400-600HP on two shafts

Single or two-story house

Twin Barn-door V-tail Rudders in a super clean flow tunnel with a shaft separation of 8'4". Twin vented full skegs protect the running gear and provide good directional stability. Full headroom engine-room with workbench, available with or without two water-tight bulkheads. This will walk a double-hull barge sideways. A big boat that doesn't get shoved around by the tow.

This is a simple boat to build, based on a series of sub-assemblies. The Deep-floors are all bent or capped. A double ladder-framed Truss supports Engine-beds, House, Knees, and "Landing Gear". This is designed to last for generations of good solid serviceable work. Easily adopted for mass-production by the smallest yards.
