This 2006 Shamrock 270 Mackinaw is a 31-foot (LOA) inboard-powered pilothouse cruiser designed for rugged, all-weather fishing and light cruising. Featuring a modified-V hull designed with a prop pocket (or tunnel) to minimize draft and shaft angle, this design offers a stable, efficient, and rugged inboard ride with a shallower draft and features a large, open cockpit and an enclosed pilot cabin. It is a durable choice for anglers seeking protection from the changeable elements of the Monterey and San Francisco Bays, as well as colder, more northern climates.
