Trailer sailer

The first trailer sailers were built in the 1950s. They were light, marine plywood boats designed for home builders. Robert Tucker in the UK designed the Silhouette, in the early 1950s. His concept was to build a small boat suitable for overnight camping, which could be trailed to different locations behind a small car. It is thought that over 3000 of this type have been built.[4][5][6] In the mid-1950s, Richard Hartley of New Zealand designed the Hartley TS16, a 16 ft long trailer sailer with a towing weight of 600 kilograms (1,300 lb). The TS16 was built in large numbers in New Zealand and Australia, spurring the popularity of trailer sailers in these countries.[7] Over 12,000 boats of this type have been built.[8]

The advent of mass production fibreglass boats in the mid 1960s saw an expansion of trailer sailer designs, such as the Aquarius 21[9] Boomerang 20,[10] Cal 21,[11] Careel 18,[12] Neptune 16,[13] and Pearson 22.[14] The Catalina 22,launched in 1969, is particularly notable as it continues in production, with over 15,000 built.[15]

Trailer cabin sailboats appeared on the US market in 1970 and were sailed on small lakes and rivers. A large number were initially sold in North America in areas such as Arizona, New Mexico and the Great Lakes region.[2]

In the late 1980s and early 1990s trailer sailers evolved into sportsboats, of a similar size but more optimised for racing speed with reduced accommodation and lightweight hulls.[16][17][18] There is an absence of an accepted definition of the term.[upper-alpha 1]

Cabins in trailer sailers are usually arranged with dual purpose settee-berths running along the side of the boat from a V-berth at the bow, to quarter berths underneath the cockpit. Usually, the centreboard or daggerboard trunk encroaches into the cabin in the middle of the boat, but can form the base for a folding table. Some types have a small four person table with club seating. Boats may or may not have a small galley with a stove, a food preparation area and a sink. In terms of headroom, the smallest types do not have sitting head room for taller sailors, while only the largest have standing headroom. Some boats address this problem using cabin pop-tops that can be raised when not underway to provide additional head room.[19]

The smallest trailer sailers in the 14 feet (4.3 m) range generally have two berths. As boats become larger four berths are commonly fitted, with a V-berth at the bow and quarter berths at the rear. Larger boats might have up to six berths. Many trailer sailers have a small galley with a stove, built in, although on smaller trailer sailers, this may be omitted. Usually, trailer sailers have a head, which is most commonly a portable toilet, mounted in the bow V-berth area of the cabin. Some larger boats however have an enclosed toilet.[19]

Trailer sailers, by necessity, must be transported by trailer, which places a number of restrictions on their design. To make them easy to launch, retrieve and transport by trailer, boats cannot have long fixed keels. Therefore, most trailer sailers have swing keel centreboards or daggerboards. Generally a trailer sailer should be towable behind a vehicle without special licences for oversized loads. This means that the beam is usually limited to approximately 8 ft (2.44 m) depending on jurisdiction. The practical limit for the length of such boats is 26 ft (7.92 m), although some trailer sailers such as the Robb Legg 28 or the Gougeon 32 are longer.[20] Weight limitations are determined by the towing vehicle. Smaller trailer sailers can weigh 500 kg (1,100 lb) or less and can easily be towed behind average cars, while larger, heavily ballasted trailer sailers can weigh over 2,000 kg (4,400 lb) require heavy vehicles with specialised towing equipment. Larger trailer sailers over 26 ft are difficult to tow and are sometimes kept in the water and only placed on their trailers for occasional towing or storage.[3]

Trailer sailer masts must be lowered for towing. This becomes difficult on larger boats with heavier, longer masts. Such boats require complex mast raising systems.[3]

Some sailboat designs for trailering incorporate special features. The MacGregor 26S, for example is a boat 25.82 ft (7.87 m) in length, but that weighs 1,650 lb (748 kg) empty and dry and carries 1,200 lb (544 kg) of flooding water ballast in tanks which are filled when the boat is launched and drained when the boat is removed from the water, thus making the boat lighter to transport than if it used more traditional iron or lead ballast. The design also has a pivoting centreboard, plus a pivoting rudder and easily rigged mast to make getting the boat from the trailer to the water easy to accomplish. It also has a beam of 7.82 ft (2.38 m), under the 8.00 ft (2.44 m) width limit for highway trailers.[21]

On the design limitations of trailerable boats with flooding water ballast, Cruising World writer Bill Lee said in 1996:

The geometry required to make a trailerable flooding-ballast boat function is such that they are a little awkward in appearance. This is accentuated by the high freeboard and narrow beam required to meet highway trailering limits ... Such boats almost always score poorly relative to their fixed keel counterparts in both sailing performance and power to carry sail. Apart from issues of portability and low cost, the more conventional fixed-keel boats ... are superior ... in most respects. Certainly if one is on a limited budget but wants a refined, good sailing, capable boat, one should consider a previously owned ... fixed-keel vessel.[22]

Most trailer sailers use a Bermuda rig with one stayed mast, a mainsail and a single foresail.[3][23]

Trailer sailers usually have a motor for docking and maneuvering. Most trailer sailers use outboard motors, which are best suited to sailboats 28 ft in length and under. Outboards offer the advantage of being light, easy to use and maintain and are also inexpensive, as they are commercially produced on a large scale and sold off-the-shelf. They can also be raised out of the water, to eliminate drag when sailing. This contrasts with inboard diesel engines which are heavy and occupy significant internal space and are best suited to larger vessels.[24]

Outboard motors used for trailer sailers need to be geared down as trailer sailers sail at slow displacement speeds compared to the higher planing speeds of powerboats, which are the most common application for outboard motors. Outboards are often mounted on the transom, with some boats mounting them in a well, also at the stern. Outboards may be mounted on a lifting mount, to allow them to be raised up out of the water. Long shaft outboard motors are advantageous, as they prevent the propeller from exiting the water and over-speeding when the boat rides over waves.[24]

Trailer sailers usually carry anchoring equipment. Due to their small size, the tackle is also light and can be lowered and raised by hand. Therefore power winches are unnecessary.[3]
