Hartley TS16/18/21
Hartley TS16/18/21 is a range of multichine plywood trailable yachts, designed by Richard Hartley.
History
The first marine ply trailable yacht designed for home construction was the Silhouette, designed in 1953 by Robert Tucker in the UK. By 1960 there were over a thousand sailing throughout the world. The concept was adopted by Richard Hartley in New Zealand with the Hartley TS16/18/21, a range of multichine plywood trailable yachts.
The plans were sold as a trailer sailer yacht.
TS16's have been built in Australia since 1963 and there TS18's from 1965 with 21's being built in the early 1960s.
Overview
The Hartley TS16 is a clean-lined, conventional trailable yacht that is the most popular in Australia. It is light, easy to rig, launch and retrieve and can be towed by a family car; 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. 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.
In Victoria, a Masthead version was developed with a staysail. This had a smaller main of 8.82 sq.m. and was intended primarily for cruising and was marginally slower than the original fractionally rigged version especially those which carried the unrestricted mainsail permitted in the Hartley plans.
Racing
When the Yachting Victoria Class Based Handicap commenced in 1986 the Masthead rig was rated at 0.590 with the fractional (3/4) rig at 0.582, but in 1982 they were combined in the Mast-rig Alternative(MA) designation on a CBH of 0.590. In 2007 after the Hartley 18-21 YC of Victoria became affiliated with Yachting Victoria it had its own designation of Hartley 18 also at 0.590 increased to 0.600 in 1999. On 14 January 2010 this designation was deleted from the CBH lists of Yachting NSW, Tasmania, Victoria and WA, while the MA was once again split into its two rig alternatives and allocated a CBH of 0.600.
When the Yachting Australia Trailable Yacht & Sports Boat Rule was established in 2008 it used the MA designation of 0.600 in common use throughout Australia but mistakenly included the CBH list of the TYA of NSW based in southern NSW which had the 3/4 rig at 0.625 based on the Mk2 racing version and a CBH for a MH* without spinnaker which had never raced. In 2010 the CBH list was changed to 0.625 for both rigs based on the racing version of the Hartley 18 but with the class rules that of the Hartley 18-21 YC of Victoria for their smaller sailed cruising version. Thus, the racing version was excluded from Yachting Australia events as a standard class yacht.

In January 2010 the designation was again split into two with a marginal increase of the CBH to .600. The rating was set by the NSW,Queensland,Tasmania,Victoria and WA authorities but it remained as .591 in South Australia.

Sailing Characteristics; Suitable for smooth and protected waters, can be stored at home and easily towed and launched. The plans for the TS18 recommends ballast of up to 150 kg forward of the centre case. This assists sailing performance. Auxiliary outboard power of 4 hp upwards is sufficient for general use with TS 16 and TS 18, with TS 21 a 6 hp is recommended.
Accommodation
Number of crew to race =2-4, Berths =2 -4, Galley =, Head =, Maximum headroom =, The TS16's relatively wide beam for a sailing boat means that it is easily driven by quite a small outboard motor and use as motor fishing boats with or without the mast raised. The TS16 also has a small cabin with two bunks which makes it possible to carry small children and picnic and/or camping gear. The cabin is adequate sleeping for two, but for more people onshore camping is necessary.
The TS18 is more suited to those who wish to sleep aboard their boat for several nights. It is most comfortable for two but can accommodate four reasonably well. Many of these boats are equipped with stoves and toilets. The TS18 can also be rigged by one person.
The TS21 is the boat for the family who wish to spend several days or more cruising. The boat has berths for four and more can be accommodated on the benches in the main cabin. However a six-cylinder car would be required for towing the TS 21.
