  • Laser Class Rules - One Design
    Laser Class Rules - One Design One of the attractions of the Laser for most owners is that the class rules are very strict and that the boat is one design. The Laser philosophy incorporated in the rules is that we want to go sailing, not waste time fddling with boats. We want to win races on the water using our skill, not by trying to fnd a way round the rules that will give us an advantage. The class rules are written to prevent any changes from the standard boat that might affect performance, so that on the water each boat is the same. The few changes to the standard boat that are allowed are minor and only to allow for a few options that make racing the Laser more comfortable and enjoyable. Over the years the class has refused to make changes to the rules that allow more expensive or complicated equipment or which makes older boats redundant. If you feel you want to change something on a Laser - STOP. Ask yourself why you want to do it? If the answer is “to make me go faster” there is a very good chance the modifcation or addition is illegal! Take a look at the Laser Rules. • Part One explains the Fundamental Class Rule which covers the philosophy and any item not specifcally written into the rules. • Part Two tells you what you must do to have a legal boat. • Part Three details a few optional changes and additions you can make. If Part Three does not specifcally allow a change or addition - IT IS ILLEGAL! If you race a Laser that has a change or addition not allowed by the class rules you will be disqualifed from the race.

  • SHALLOW BOATS; DEEP ADVENTURES! Since 1984
    Since 1984 SHALLOW BOATS; DEEP ADVENTURES! 1 SHOAL DRAFT STABILITY, SIMPLICITY, SPEED AND SAFETY. I’m here to talk about a belief in and a passion for shoal-draft boats, particularly the development of the Round Bottomed Sharpie. I started sailing in centreboard dinghies and that excitement has returned with these boats. As you’ll see these 2 boats have become known as Presto Boats. NEW HAVEN OYSTER- TONGING SHARPIE By definition a Sharpie is a flat-bottomed boat and a New Haven oyster-tonging sharpie looked like this. They were easy to build with their box shape & simple rigs but the boat is an ingenious piece of function and efficiency. The stern is round so the tongs don’t snag on transom corners; the freeboard is low so it’s easy to swing the tongs on board and the long centreboard trunk stops the oysters from shifting SEA OF ABACO 3 under sail. NEW HAVEN SHARPIE RIG The unstayed masts rotate through 360 degrees so the oystermen would sail to windward of the oyster beds and let the sails stream out over the bow while drifting over the beds tonging away. The sails are self-tending and self-vanged so handling is very easy. The boats are fast when loaded so you can get the oysters fresh to market. Oyster bars in big cities were the Starbucks of the late 1800s. You’d pop in for a ½ dozen as a pick-me-up. 4 On the right is an Outward Bound 30 to our design. With our contemporary Sharpies we’ve retained the principles of the traditional rig; it works as well today as it did in the 1800s.

  • Excerpts from a Sailor's Wind Journal
    A Fine Reach Home: Excerpts from a Sailor’s Wind Journal Lynn Fels English Bay, 1976, International 14 We surface amidst sodden sails, shouting in surprise and haste. “Are you okay?” “Where are you?” “Hang on to the gunwale, no wait, swim the bow into the wind, now swim over here, we’ll bring her up together.” Martin and I, skipper and crew, throw our weight onto the centerboard. The boat reluc- tantly responds, the mast tilting skyward, rising from the sea. I taste the salt of ocean spray that catches me unaware after so many years of sailing fresh-waters. Equilibrium restored, seawater emptying through the automatic bailers, our sailboat moves across the water in ecological tension between human, craft, wind, and geography. Martin tends to the navigation, attentive weight- ing of hand on tiller, as I set the jib and cleat the sheet. Shifting body weight, secured by the trapeze,I feel the arc of body, an embodied inter- pretation of movement in response to the wind’s presence in the tautness of the sails. Sailing in the various conditions of wind requires an instinctive chore- ography of release and defiance, surrender and embrace, by skipper and crew. 180 Canadian Journal of Environmental Education, 13 (2), 2008 This is what holds me to task, as I swing in and out of the boat secured to the mast by the trapeze wire that holds me in place. “Wind’s coming! Trapeze!” Martin yells, but I am already in concert with the wind, welcoming its arrival, anticipating its departure. Sailing, a harnessing of wind with canvas to propel a sailboat across dis- tances of water, in winds shaped by landforms, airflow and temperature, requires constant renegotiation by skipper and crew in response to the wind’s changeable presence.

  • The Hansa 303
    YACHTING NEW ZEALAND INCLUSION RESOURCES THE HANSA 303 THE HANSA 303 Hansa Dinghies are designed with a hull form, ballasted centreboard, and other features which combine to give considerable stability. The term dinghy is used for convenience; however the boat behaves more like a small keel boat and should be treated like one. When the wind increases the sailors cannot sit out over the side to balance the boat. Instead, the sails need to be reefed in (see notes on reefing). These boats will still sail well with only the mainsail set. There are some best practices you should follow to maximise enjoyment and prevent any accidents. Specifications Length 3.03 m Beam 1.35 m Draft 1.0 m Weight 55 kg + centreboard 30 kg Sail Area 5.8 m2 (Reduces to 0.5 m2) Mast Main - Unstayed 4.75 m Jib – Unstayed 2.85 m Capacity 160 kg 303 Wide 303 Wide YNZ Inclusion Resources 2015 2 303 B The stability of the Hansa 303 Dinghy is reliant upon the following factors. SEATING Because the placement of sailor’s weight affects stability it is important that people remain seated low in the boat. When being crewed by two sailors, they should be similar weights where possible. If you are using foam wedges and quick release straps to hold them in place, the keel must be locked fully down and the locking pin in place KEELS It is most important that the keel is always fully down when sailing. The hole for a short keel pin (1/3 way down the keel) is there purely to facilitate launching off a beach or boat ramp.

  • The Development of a Light Weight Centreboard
    The development of a light weight centreboard. As I am sure some of the Phanmail readers will be aware, I have been renovating my recently purchased Claridge hull, number 906. She was a fair bit over weight – a certificate in 1998 stated 68kg – and I am rather over zealous with these things so she HAD to be to weight when she was returned to racing trim. This article is intended as a long-winded guide to how I have got on with that campaign. As the rules declare that you are not allowed to remove constructional materials, the fittings and attachments were the main targets. An obvious place to start (as I was removing layers of paint and varnish) was the centreboard. The existing board looks like the original article, made in wood with a glass fibre coating. It weighs about 4.5kg. I remember from my previous time in Phantoms that Bloodaxe made a centreboard in carbon with a foam lay-up for another Claridge #903. So it is possible to get something light, stiff and workable the only downside is cost. This was a major consideration as the agreement with my wife that I could buy the boat in the first place was that I did not spend any money on it. Oh well. I also wanted to play with the shape (I am a Naval Architect so these things interest me). Recent thoughts in the class have seen boards narrowing to around 250mm at the hull exit. I wanted to develop along these lines, so I got a colleague at Work (Sunseeker) to scan my existing board into our CAD package and use that as a starting point.

  • APPENDIX 1 Righting the Chichester Scow After Capsizing
    Flight Marine Limited - 1 - Chichester Scow APPENDIX 1 Righting the Chichester Scow after capsizing. Sooner or later most people experience a capsize. It's usually caused by an accidental gybe or by getting some part of the boat tangled with an obstruction. Here are a few tips that should enable righting of the Chichester Scow without external assistance. In a capsize the Chichester Scow initially remains in a 90 degree position. The buoyancy of the lug and mast sometimes keeps it in this attitude. It may have been possible to simply climb down from the windward side to stand on the centreboard and right the scow very quickly. However, it is also possible that the weight of the crew clinging to the hull will turn the scow to a fully inverted attitude. The centreboard will then fall back into it's case and another righting method must be employed. The scow floats quite high when inverted, so it is fairly easy to reach under the foredeck and find the painter, which should have it's bitter end tied through the foredeck cleat. Gather up the loose end of the painter and move it aft leading it inside one of the shrouds. Then throw the loose end over the inverted hull. Move round to the other side and grab the painter. Now push down on the underside of the gunwhale whilst pulling the other side up with the painter. Flight Marine Limited - 2 - Chichester Scow This starts the righting process. The gunwhale on the crew's side can be immersed further if the crew puts his/her feet on the underside of the gunwhale whilst maintaining tension on the painter.

  • OFFSHORE RACING CONGRESS ORC VPP Documentation 2013
    ORC VPP Documentation. DRAFT 2010_1.0 World Leader in Rating Technology OFFSHORE RACING CONGRESS ORC VPP Documentation 2013 Updated July 4th. orc vpp documentation 2013‐issue‐1.2.doc Section 1 Page 2 1 Background. The following document describes the methods and formulations used by the Offshore Racing Congress (ORC) Velocity Prediction Program (VPP). The ORC VPP is the program used to calculate racing yacht handicaps based on a mathematical model of the physical processes embodied in a sailing yacht. This approach to handicapping was first developed in 1978. The H. Irving Pratt Ocean Racing Handicapping project created a handicap system which used a mathematical model of hull and rig performance to predict sailing speeds and thereby produce a time on distance handicap system. This computational approach to yacht handicapping was of course only made possible by the advent of desktop computing capability. The first 2 papers describing the project were presented to the Chesapeake Sailing Yacht Symposium (CSYS) in 1979.1 This work resulted in the MHS system that was used in the United States. The aerodynamic model was subsequently revised by George Hazen2 and the hydrodynamic model was refined over time as the Delft Systematic Yacht Hull Series was expanded3. Other research was documented in subsequent CSYS proceedings: sail formulations (20014 and 20035), and hull shape effects (20036). Papers describing research have also been published in the HISWA symposia on sail research (20087). In 1986 the current formulations of the IMS were documented by Charlie Poor8, and this was updated in 19999. The 1999 CSYS paper was used a basis for this document, with members of the ITC contributing the fruits of their labours over the last 10 years as the ORC carried forward the work of maintaining an up‐to‐date handicapping system that is based on the physics of a sailing yacht.
