2006 Shamrock 270 Mackinaw Cruiser

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. 

Key Features and Design:

• Length: 31' (LOA); actual hull length is ~ 28' 10", but overall length is 31', including the bow pulpit.
• Engine: Inboard (single) Yanmar 24-valve, 315HP Diesel, 50 hours (new in 2023); Bennett recessed hydraulic trim tabs; Racor fuel/water separator; fresh water cooling; Seastar hydraulic steering.
