Welcome to the Westerly Wiki sponsored by the Westerly Owners Association. Our aim is to make the WesterlyWiki the prime source of technical information about Westerly Yachts. The Wiki is under construction so you will find many empty pages and as this is a Wiki you are invited to help to fill them. The Wiki is an open (public) resource and anyone may contribute material or correct existing entries (see Guidance for Contributors below). However you do need to register your email address (using real names please) and log in to contribute - anonymous access is not supported.

The Westerly Companies
Around the start of 1963 Commander Denys Rayner, an established yacht designer (see Before Westerly), was approached by Hilary Scott, a man of some means, to design a GRP yacht to be built by a new company he wanted set up. Rayner designed the Westerly™ - a 22ft yacht similar in some respects to a wooden yacht he had designed earlier; the boat was subsequently renamed the Westerly 22™. After some discussion, Rayner became MD of the new company, whilst Scott and a solicitor called Michael Hurd became its non-executive directors. That company, founded in March 1963, was called "Westerly Marine Construction Ltd"™, the first of several companies to own the Westerly brand name, and usually referred to as just "Westerly" see A Brief Corporate History of Westerly Over the decades that Westerly in it's various incarnations dominated the UK leisure yachting industry they employed the best designers of the day including John Butler, Ian Proctor , Jack Laurent Giles, Chris Hawkins, Mike Pocock, Ed Dubois, and Ron Holland; and from beginning to end, Westerly established and maintained a reputation for their excellent GRP layup and strength of build.

Looking After your Westerly
Yard Numbers, Sail Numbers, and Hull Numbers
The Yard Number is the definitive way to identify a Westerly, because it is unique to each boat. It is the number on the plate in the hatchway. It consists of a letter then some numbers i.e. A 123. ~The very early Rayner designs used a system that is slightly different from that used on the Laurent Giles designs, and the very late models used a slightly different system again.
There is a school of thought that the prefix letter originally indicated from which shed in Waterlooville the hull was made, but this isn't substantiated. What is known is that the system represents the specific model being built. The digits represent the number of that specific hull. The yard number is also found on cabin fixtures and fittings, written in pencil or wax crayon on the underside of removable wood panels such as locker lids. It has also been found on various parts such as skin fittings.
The Sail Number is sometimes, but not always, a different number to the hull number. Some boats were registered internationally so weren't given class numbers (GK24s for example). Sail numbers were issued numerically and in series when orders were placed, but if orders were cancelled the next ordered Sail Number was issued to the next hull coming off the production line. As the hulls were coming off the production line in numerical order, the Sail Number issued to it was the next ordered and paid for Sail Number. In this way, Sail Numbers and Yard Numbers got jumbled up. A further complication to be added into the mix is that some designs used the same hull but different deck mouldings. In addition, it is known that some numbers were specifically requested by new purchasers, and Westerly granted those requests. And some numbers were just not issued - 666 being a good example. And, of course, over time sails are bought and sold, and it is not unknown to have Westerly's using a sail that was not supplied with the boat!
The Hull Numbers were stamped into the moulding of the hull on the stern of the boat on either the port or starboard side near the top of the hull. It is linked to the Certificate of Hull Construction number issued by Lloyds Register of Shipping and is in the form ABC 123456. The vast majority were issued by the Southampton office, so start with SOU, and invariably the last 2 digits indicate the year the hull was laid up. There is an example of a 1977 Centaur Hull Number here: . Early Centaurs (prior to 1973?....any advances on '73) do not appear to have this.
If by chance your boat's Yard Number and Sail Number coincide, that is a rare occurrence on most Westerly's. Some did match - Corsairs for example, will match. More often than not the numbers do not coincide and because a Yard Number is 219 it does not mean that the Sail Number is 219. For example the Renown shares the same hull with the Pentland, and the very first Renown built R1 has a Yard Number of O (oscar) 036. The original author of this submission owned a Renown that had a sail number of R129 but a Yard Number of O (oscar) 243.

Guidance for Contributors
This is an open Wiki so anyone can contribute. Please open an account and log in using your real name. The basic syntax is simple so with a little reading through the Help under Navigation and/or the FAQ link below any one can enter material and edit text. For more complex layout editing some knowledge of a language such as HTML will help or you can email the Sysops and leave a request for support at firstname.lastname@example.org. Contributors should endeavour to review the best available information on a topic and submit a digest of that information to the Wiki. Prime sources of information will include personal experience (preferred), magazines, the WOA Web site and discussion groups such as WOA and Yahoo. Material should not be lifted verbatim rather a digested version should be presented in the Wiki. There are generally several alternative approaches or opinions about any task and Wiki contributors should endeavour to identify these alternatives and provide hooks (follow on pages) to the alternatives. Even if the information is not available to the original contributor someone else can later add that information. Reprints of chatty Practical Boat Owner type articles are not recommended because this is not Wiki style. The "How I did it" article which is suitable for a magazine is generally just one view and the Wiki needs to recognise alternates. You should also add a Resources section where applicable providing links to suppliers web sites and a References section listing sources of material used in the compilation of the section.
