Motorsailers are cruising yachts designed to use engine and sail as co-equal means of propulsion, in contrast to conventional sailing yachts where the engine is an auxiliary, and motor yachts where sail is absent or vestigial. They are built for comfortable, reliable long-distance coastal and offshore cruising by owners who prioritise passage-making certainty over sailing performance.
The type originated in northern Europe — particularly Scandinavia, Britain, and the Netherlands — where variable winds and commercial shipping routes make engine-dependent passages a practical reality rather than a compromise. A characteristic feature is the raised pilothouse with an interior helm station, allowing the skipper to manage the vessel in cold, wet, or rough conditions without going on deck. The sail plan is typically smaller relative to displacement than on a pure sailing yacht, which reduces upwind performance but makes the rig easier to handle short-handed. With sails set, even in insufficient wind to drive the boat, the rig provides roll damping that improves comfort under power.
Construction is GRP for most production examples; steel and aluminium are used on custom and semi-custom bluewater builds. Hull forms are semi-displacement, allowing efficient motoring at 7–10 knots without the fuel penalty of pushing a full-displacement hull above its natural speed. Inboard diesel with shaft drive is standard; engine compartments are typically larger than on equivalent sailing yachts to accommodate the higher-output engines that motorsailer owners expect to run for extended periods.
