Bolger Martha Jane

Description

The "Martha Jane" is a 23'6" (7.16 m) plywood sharpie yawl—specifically a cat-rigged sharpie with a small mizzen sail—designed by Bolger in the 1980s. Featured prominently in his book Boats with an Open Mind (International Marine, 1994), this open camp cruiser emphasizes Bolger's core tenets: radical simplicity, low cost, and surprising performance for backyard builders. It's an evolution from earlier designs like the Black Skimmer, blending a boxy "Bolger aesthetic" (high freeboard, flat panels) with seaworthy traits for coastal or bay cruising. The name "Martha Jane" honors a friend or client, typical of Bolger's personal touches.

Custom sail calculations are not possible for this boat as no I, J, P and E dimensions are available.
