Bolger Instant Cat

Description

The Bolger Instant Catboat, commonly known as the "Bobcat," is a compact, gaff-rigged catboat designed by the prolific naval architect Phil Bolger in 1985, specifically crafted for amateur builders seeking a quick, rewarding project in the spirit of his "Instant Boats" series. Collaborating with boatbuilder and author Harold "Dynamite" Payson, Bolger adapted the classic lines of the venerable Beetle Cat (a 12'6" wooden icon from New England) into a modern plywood version using stitch-and-glue construction—eliminating lofting, jigs, and complex joinery to make it truly "instant." This single-masted daysailer emphasizes simplicity, stability, and spirited performance in protected waters like bays, lakes, and coastal sounds, carrying one to three adults with ease. It's not a blue water beast but shines as a forgiving trainer or picnic boat, planning in light breezes and rowing adequately when becalmed. Featured prominently in Payson's 1993 book Build the Instant Catboat, the Bobcat has inspired hundreds of backyard builds, embodying Bolger's mantra of accessible, efficient small craft that prioritize fun over frills.

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

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
