Bronze Sail Level IV – The first section deals with safety and the factors in your local area such as currents, tides and weather which should be considered before going sailing. The three types of flotation commonly found in dinghies and the factors which affect the self-rescuing capabilities of a dinghy And finally a look at chart of unfamiliar waters and identification of hazards and means of recognizing them.
Seamanship is the next section and students will demonstrate their ability to whip the end of a line with a plain whipping of appropriate length, make a back splice and an eye splice and heave a 10 metre line to land across a 1 metre diameter target at least 7 metres away, in three tries out of four.
The next section is further nautical terminology. Following that is some sailing theory including leeway and its importance on different points of sail. The centre of lateral resistance (CLR) and centre of effort (CE) affect lee and weather helm in theory and practice, weight distribution and centreboard adjustments affect on the CLR, the boat’s underwater shape affects its helm, sail trim, mast rake and position affect the CE and helm, draft (fullness in a sail) is and how it affects the power and the pointing ability of a sail, the use and position of telltales on shrouds and ticklers on a sail.
The next section considers sail shape and how the main sail is affected by halyard tension, mainsheet tension, cunningham tension, traveller position, outhaul tension, mast bend, boom vang tension and mast rake. And how the shape of the jib sails affected by halyard tension, sheet tension and fairlead position. The use of outhaul, cunningham, mainsheet, and traveller, while sailing on a beat, a reach, and a run under the following conditions. On the water students will be asked to skipper and crew the boat on various points of sail and tacking and gybing. Carry out a self-rescue after capsizing in a dinghy and carry on sailing with a minimum time delay. Carry out the following tasks without a rudder, sail a course upwind toward a predetermined destination, make at least one controlled tack and settle down to a course to the predetermined destination, bear away or tack and return to the starting position. With sails backed, sail the boat astern to a predetermined destination 90 metres downwind.
On completion of this level IV the candidate will be able to understand and apply the basic principles of sail trim and boat tuning for optimal performance in wind speeds of 9-14 knots.
