Chichester Scow Class Association

The purpose of this document is to introduce you to the Chichester Scow Class [CSC] and tell you most of what you need to know if you are thinking of joining us. The class was introduced in the year 2000 and has developed rapidly from four hulls to over fifty as the only class for one-design racing at Bosham Sailing Club. As an essential part of this process, the owners formed a One Design Association and agreed a set of One Design Rules to manage the project.While the design is that of a traditional scow and can be seen as just one of many slightly different and popular scow designs around the whole Solent, it is inexpensive and has been kept simple by the One Design Rules. The Association looks after the Class as a whole, not just the Bosham Sailing Club fleet, and inter alia, seeks to maintain a firm grip on costly developments to keep the price of this design down. At Bosham the Chichester Scow Class is entitled to its own club starts and races, competitions and prizes and provides a full annual programme of events, including non-racing social events. Whether you fancy one-design racing at something less than the highest level or just pottering about in the harbour, get a Chichester Scow, tell a member of the Class Committee and then you will receive all the information and bits of paper to tell you what it is all about in detail i.e. a handbook giving the Association and One Design Rules, Plus several extra forms, like Association membership application £5 per year, responsibility disclaimers, social and racing programmes, etc. If you need to know anything which is not covered here, ring Sandy Woodward (Chairman)on 01243 573555 or David Ware(Bosham Scow Class Captain) on 01243 574010. The Chichester Scow itself is of GRP construction to a safe, simple design, unusually stable, suitable for young and old. When you do nevertheless get it all seriously wrong , it is easy to right after a capsize and its built-in buoyancy makes it almost impossible to sink unless you load it with concrete blocks. It can take two easily but is more usually raced with only one aboard. The CSCA Secretary who records all things is[presently Liz Adams on 01243 574792 or on Email at lizzybozzy@ hotmail.com. In addition to standard kit supplied on delivery of a new scow, you will often need to wear a buoyancy aid. You will also be well-advised to provide yourself with the course cards for your club, a chinagraph pencil/whiteboard pen, and oars/paddle/praddle. You may wish also to fit a big streamer for telling the wind direction when going downwind, extra tell-tales on the sail and maybe even a little Windex which straps to the mast. Tweaks and Tips. There was a section started in the Spring 2002 Newsletter on tweaking your scow for best performance, and to give tips on sailing it. This is a dynamic area, always liable to change, not definitive and only intended as suggested help. Different scow owners will have different opinions on many of them. Some you will find are in general use. The standard scow you get from the builder is perfectly capable of racing competitively as it is - these tips serve only to help refine your performance - you may already be good enough without them. If you choose to go further with joining the Association and taking part in One Design racing, you will be sent [by Email] :- The Class Handbook containing this introduction and: CSCA Constitution, CSCA One Design Rules, CSCA Membership application form. When your application has been processed, you will receive Annual papers covering Protest Procedure advice, Notice of Race and Sailing Instructions, Consolidated programme. CSCA Owners list and Latest Newsletter Papers List.

CHICHESTER SCOW CLASS ONE DESIGN RULES

The Chichester Scow is a one design scow built only by Flight Marine Limited. The intent of these rules is to maintain the Chichester Scow as a simple and economical one design class, but not to prevent adoption of simple and inexpensive modifications. The Chichester Scow Class Association is responsible for the maintenance of these rules and inspection/acceptance of modifications. Both GRP and wood/epoxy Chichester Scows should comply with these rules in order to join Chichester Scow one-design races. Although some Chichester Scows are supplied with jibs, their use is not permitted in Chichester Scow One Design racing.
