The painter, a rope used for securing a boat like a mooring line, is usually tied around the mast step.īuoyancy bags are installed inboard along each side in the front half of the boat and at the stern to provide buoyancy in the event of capsizing. At the bow resides a thwart to support the mast which passes through a hole in its centre to the mast step mounted on the centre line of the boat. These anchor the sheet and a block on the boom directly above. Right behind it on the centerline of the hull floor are attached a block and a ratchet block. Just in front of a bulkhead, which partitions the boat nearly in half, is the daggerboard case.

It was the biggest hull Clark Mills could make from two 4 ft by 8 ft sheets. The Optimist has a pram hull, originally formed primarily from five pieces of plywood. Optimists also have a national sail number using the Olympic abbreviation of their country and a sequential numbers. The spars may be made from aluminium or wood, but are invariably aluminium in modern boats.Ī monograph-style 'IO' insignia (after IODA - the International Optimist Dinghy Association) on the sail is a registered trade-mark and may only be used under licence from the International Optimist Association. Raising and lowering the sprit and adjusting the boom vang and outhaul allow for adaptation of sail trim to a range of wind conditions. The light, slim third spar, the sprit, extends through a loop at the peak of the sail the bottom rests in the eye of a short cable or string which hangs along the front edge of the mast. It is secured evenly with ties along the luff to the mast and along the foot to the boom, pulled down tightly by a vang/kicker. The single sail of the Optimist is sprit-rigged. The design was standardized in 1960 and became a strict One-Design in 1995. The design was slightly modified and introduced to Europe by Axel Damgaard, and spread outwards across Europe from Scandinavia. He designed a simple pram that could be built from two 4' x 8' sheets of plywood, and donated the plan to the Optimists. Thus they were looking for a low-cost equivalent for sailing. The Optimist Club ran a soap box derby, but wanted more than a single-day event. The Optimist was designed in 1947 by American Clark Mills at the request of the Clearwater Florida Optimist service club following a proposal by Major Clifford McKay to offer low-cost sailing for young people. It is sailed in over 120 countries and it is one of only two sailboats as an International Class by World Sailing exclusively for sailors under 16. The Optimist is one of the two most popular sailing dinghies in the world, with over 150,000 boats officially registered with the class and many more built but never registered. The Optimist is a small, single-handed sailing dinghy intended for use by young people up to the age of 15.
