About the Morgan Out Island 33 Ms

Designed as a motorsailer variant of Morgan's popular Out Island series, this 33-footer represents the builder's attempt to bridge the gap between pure sailing and motor cruising. The "Ms" designation indicates its motorsailer configuration, featuring a larger engine compartment and modified sail plan compared to the standard Out Island 33. Morgan built these boats during the company's heyday in the 1970s and early 1980s, when fiberglass construction was becoming refined and production sailboats were gaining widespread acceptance. The Out Island series earned a reputation for solid construction and practical layouts that appealed to cruising sailors seeking affordable offshore capability. This motorsailer variant would have been marketed to sailors who wanted the security of substantial engine power for challenging conditions or tight anchorages, while retaining the ability to sail efficiently in favorable winds. The design likely features a cut-away full keel typical of the Out Island series, providing directional stability and protection for the propeller and rudder. Given Morgan's focus on cruising boats, the Out Island 33 Ms would be well-suited for coastal cruising and extended passages where reliable auxiliary power complements sailing performance.
