History

The first marine ply trailable yacht designed for home construction was the Silhouette, designed in 1953 by Robert Tucker in the United Kingdom.[1] The concept was adopted in 1959 by Richard Hartley of Auckland, New Zealand, when Hartley created a range of multichine plywood trailable yachts starting with the TS16, calling the concept a 'Trailer Sailer'.[2] Hartley added to the range with the TS18 in 1963 then the TS21. The "Trailer Sailor Association of Australia" was formed on 12 December 1963 to encourage the growth of the TS16 as a one-class design, and the association continues to operate today.[3]

While the Hartley 16' design is generally built in wood, molded fibreglass models are also available.[2]

Overview

The Hartley TS16 is a clean-lined, conventional trailable yacht that is the most popular in Australia.[4] Designed along the lines of the mullet boats from New Zealand, the boat has a wide beam and good performance.[5] It is light, easy to rig, launch and retrieve and can be towed by a family car;[4] many have been built by amateur builders. The later advent of fiberglass trailable boats and increasing materials cost reduced the popularity of home builds. Many of them are raced, but are not allowed to use a spinnaker.

The Hartley TS18 was a development of the 16 with more emphasis on family cruising being 10% larger with accommodation for four people. In total some 240 were built in Australia of which less than 40 were ever raced. Of these 220 were the standard Hartley designed fractional rigged boats, and 20 the Victorian Association Masthead version.A later trend was to set up the yacht as fractionally rigged but carry the Mast Head rigged spinnaker; this gave better performance.

The Mk1 had a 13.38 sq.m mainsail but as most cruising yachts only carried the working jib, it was found to have weather helm. Thus, the Mk 2 was developed with a shorter 3.2 m boom with a smaller 11.8 sq.m mainsail for cruising with. However, there was no restriction on the size of the roach for racing with the genoa, thus the standard for competition became 14+ sq.m and was fully battened for better control. The Mk2b was then introduced with a longer cabin for more comfortable overnight accommodation, and finally the Mk 3 with a more streamlined cabin profile and a longer waterline.

Several Mast Head Spinnaker(MHS) Hartley 18' boats were built having the 3/4 rig main and genoa along with the MH spinnaker.

In Victoria, a Masthead (MH) version was developed with a staysail to go with a small mainsail of 8.82 sq.m. intended primarily for cruising. This version was marginally slower than the original fractionally rigged version especially those which carried the unrestricted mainsail permitted in the Hartley plans. So the two rig configurations could compete on equal terms the Victorian designer introduced a modified fractional rig with the same total sail area. This design was adopted by the Victorian Class Association as a 'Modified Boat' from the Richard Hartley published plans.The Victorian designer modified the hull and foils. It had a thicker 75kg heavier centreboard so there was no meed to carry 150kg+ of internal ballast, so significantly reducing total sailing weight. Boats intended for racing were also built using lighter timber and plywood. The result for the Victorian Class Association approved modified boat was a minimum weight of 573 kg compared with 694kg for a boat built to the Richard Hartley specifications and recommendation. This modified boat had a separate CBH designation of 'Hartley 18', which caused some confusion as some clubs only used 'Hartley 18' for the 'Hartley 18 M/A' designation which had existed since 1992.

The Hartley TS21 was a further development of the Hartley 18 designed to give more room for four people as a cruising yacht.

Racing

The Hartley 16' was primarily used for racing when the spinnaker was not allowed to be used. They tended to be raced at clubs as a single division under the YA Special Regulations Part 2 'Off the Beach Boats' in the category 'small trailable boats'. An annual national championship is held.

The Hartley 18' was predominantly built for family cruising, and less than 40 of the 240 built in Australia were ever known to have raced Some raced as in the YA Special Regulations Part 1 as Trailable Yachts in a mixed trailable yacht division, but in the majority of clubs In they raced under the YA Special Regulations Part 2 for 'Off the Beach Boats'. Due to the few Hartley 18s raced there never has been a national championship for the class,

The Hartley 21' was normally only used for family cruising purposes.
