Trailer Sailer

A trailer sailer is a small yacht or large dinghy style of sailboat that is moved to sailing locations and stored on a road trailer. It is neither a Day sailer or a Pocket cruiser but may be used for either purpose depending upon design suitability. The large dinghy style relies principally on correct crew weight for balance rather than fixed ballast, much like a dinghy and is suitable for use only on protected water. The other style is a Trailer yacht, which has a proper yacht ballast ratio of at least 30% excluding crew weight. This latter style is suited to yacht racing or cruising on inshore waters and along coastlines; a good example may pass self-righting tests and be suitable for Junior Offshore Group (JOG) or English Channel events or similar. Other designs are a compromise between the two principal types. An emerging type is the Sportsboat with a proper yacht ballast ratio, but large sail areas requiring crew weight positioning for stability, with their own design and self-righting rules. One feature that distinguishes Trailer Sailers from other small yachts is the need to launch from and recover to a road registered trailer, which can place constraints on dimensions and weights. They may vary in length from 5 to 10 metres; above that the length-width ratio is not ideal. In addition the mast and rigging must be suitable for ease of raising and lowering. The keel is most often not fixed but may be retracting, removable or swing, hydraulic, winch or electric operated and the ballast may be water that is drained to reduce weight for trailing. For simplicity and weight saving they are more likely to have a removable outboard engine.

Inherent in the design of yachts with lifting keels is the ability to approach a beach or landing close enough that the occupants may wade ashore. Such craft can sit on the bottom comfortably when the tide recedes (often referred to as "drying out"). Shallower cruising grounds can also be more readily, and safely, accessed. Lifting keels also permit the boat to be stored on the trailer at home or onshore at a marina or boat club rather than on a mooring, thus making them cheaper than larger boats. Another advantage is the quick movement between different cruising grounds: it may take weeks to sail a yacht to a new destination, whereas it may take only days to transport it by road .
