Pen-Hir

Designed by François Vivier

Pen-Hir is a 7.49 m coastal cruiser with a 2.50 m beam that François Vivier drew for his own use, wanting a moderate boat that is easy to handle alone and able to spend a fortnight away without a diesel engine. Her profile follows the boats of the Brest and Carantec areas, with a vertical stem and a short counter stern.

She is rigged as a gaff sloop with the jib on a short bowsprit, carries 600 kg of lead ballast on a long keel, and can dry out on legs. The designer notes she can still be trailered. The plans were revised in 2023, with a new construction manual built from a 3D model. Building her requires a plywood kit or CNC cutting files in addition to the plan.
