Sail Power and Performance
the area of Ihe so-called "fore-triangle"), the overlapping part of headsail does not contribute to the driving force. This im plies that it does pay to have o large genoa only if the area of the fore-triangle (or 85 per cent of this area) is taken as the rated sail area. In other words, when compared on the basis of driving force produced per given area (to be paid for), theoverlapping genoas carried by racing yachts are not cost-effective although they are rating- effective in term of measurement rules (Ref. 1). In this respect, the rating rules have a more profound effect on the plan- form of sails thon aerodynamic require ments, or the wind in all its moods. As explicitly demonstrated in Fig. 2, no rig is superior over the whole range of heading angles. There are, however, con sistently poor performers such ns the La teen No. 3 rig, regardless of the course sailed relative to thewind. When reaching, this version of Lateen rig is inferior to the Lateen No. 1 by as rnuch as almost 50 per cent. To the surprise of many readers, perhaps, there are more efficient rigs than the Berntudan such as, for example. La teen No. 1 or Guuter, and this includes windward courses, where the Bermudon rig is widely believed to be outstanding. With the above data now available, it's possible to answer the practical question: how fast will a given hull sail on different headings when driven by eoch of these rigs? Results of a preliminary speed predic tion programme are given in Fig. -

The Vanuatu “Butterfly Sail”: a Polynesian Oceanic Spritsail in Melanesia
The Vanuatu “Butterfly Sail”: A Polynesian Oceanic Spritsail in Melanesia ANNE DI PIAZZA Before the time when the labour trade made the natives afraid to move about, and “recruiting” meant destruction of canoes for the capture of their crews, red “butterfly” sails were the common and pleasing ornament of an island scene in the New Hebrides and Banks groups. —Codrington 1891 : 292 introduction In the first volume of PIROGUES OCÉANIENNES, Father Neyret, a Marist missionary assigned to Fiji, the Solomon Islands, and New Caledonia, wrote: The most beautiful examples of naval construction are the canoes of Malakula and its neighboring islets: the most typical model is the magnificent high seas outrigger canoe . , a model that must figure among the most original and interesting of those of Melanesia, and which gives us a clear idea of the creative qualities and ingeniosity of these populations, so long discredited by superficial observers in search of the sensa- tional. ( Neyret 1974, vol. 1 : 31, my translation)1 He concluded that: [The butterfly sail] is a variant of the simple triangular sail [Oceanic spritsail] used in East Polynesia. But while in Polynesia it is used only on monodrome [tacking] ca- noes, in the New Hebrides [Vanuatu] it has been adapted to the amphidrome [shunting] maneuver. Although it may equally be a local invention. ( Neyret 1974, vol. 1 : 183, my translation)2 Neyret’s text merits close attention because Neyret is one of the few researchers to have used canoes as markers for migratory history. More importantly, he is the only one who specifically looked at the butterfly sail in Oceania. -

Rigging Documentation and Sea Trials of Philip Maise's Aft-Mast Mounted Semi-Double Crab Claw Rig
Rigging Documentation and Sea Trials of Philip Maise's Aft-Mast Mounted Semi-Double Crab Claw Rig Dates: November 29th – December 3th , 2010 Location: South China Sea ….Singapore to Brunei Winds: 0 Knots to 11 Knots Seas: Calm to light depending upon day and time Boat: Philip Maise's 65ft Trimaran Loading: 2 Crew including master/owner 7 Tenders 150 HP engine Dingy Engine 2800 Liters of fuel and water 80 Liters of Oil 4 Month supply of food 3 Large Anchors 1 Small 2 Sea Anchors 4 Sails 1 Piano, Full Size Oven, Tools, and Misc. Sails and Placement: Small Crab Claw Sail No. 1 with attachment at the 67ft mark. Comment About Loading....The trimaran was fully loaded for long term cruising. Test results were not skewed by emptying the boat. Test Objectives: Video self tacking. Identify weaknesses in rigging Deck hard ware Tension Rigging . Upwind Testing Disclaimer: This documentation is not intended to be used by anyone to modify or build their own sail boat. Test Results and Comments; I'm very pleased to report that in summary testing went very well. I learned vital information regarding the combined functionality of the boat, sail, rigging, and mast. I'm excited about the prospect of taking this knowledge to the next level to incorporate what I learned into an even better combination. November 29 th , 2010 We had very light winds insufficient for any testing. However, we still raised the sail and spent most of the day adjusting multi-blocks to control the spar in the sail. Near dusk a squall hit and we pulled up on the spilling line to reduce the exposed sail area. -
