Ellen Gunter Rig

Description

The Ellen Gunter Rig is a sailing configuration featured on the Ellen 12, a compact 12-foot lapstrake (clinker-built) dinghy designed by John Brooks of Brooks Boats Designs in Brooksville, Maine. Introduced in 1996, the Ellen 12 is renowned for its classic aesthetics, ease of construction using glued-lapstrake plywood, and versatility as a tender or standalone daysailer. The "Gunter Rig" refers specifically to the optional sliding gunter rig, a compact, gaff-like setup with a vertical reefing system that allows quick adjustments without dropping the sail—ideal for short-handed sailors or variable winds. This rig contrasts with the standard spritsail option, offering a taller sail profile for better light-air performance while maintaining simplicity. Over 100 Ellens have been built, many in workshops at the WoodenBoat School, where Brooks teaches glued-lapstrake techniques.

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