Paper presented at the SNAME 23rd Chesapeake Sailing Yacht Symposium, March 15–16, 2019
Paper Number: SNAME-CSYS-2019-004
... The rise in interest in large foiling yachts, such as those in the America's Cup, has spurred a corresponding interest in foiling applications in monohull sailing dinghies, both for boats designed specifically for foiling, and through retro-fit foil kits. The present study considers...

The set of possible routes are then obtained by using an iterative multiple objective optimization algorithm. Isochrone algorithm is used for initializing the set of routes. Then mutation operators are used...

... Two boats sailing in close proximity may inevitably compare their boat speeds, perhaps even "race" each other. Over the last few centuries there have been numerous handicap systems designed to equalize the competitive chances of racing sailboats. Corollary to handicapping is another arcane art...

... force model, a hydrodynamic force model and an algorithm to balance the forces. The force balance routine uses four degrees of freedom; boat speed, yaw, heel and rudder angle to balance the aerodynamic and hydrodynamic forces for a given true wind speed and angle. The force models are derived from RANS...

Paper Number: SNAME-CSYS-2016-005
... In small sailboats, the bodyweight of the sailor is proportionately large enough to induce significant unsteady dynamics of the boat and sail. Sailors use a variety of techniques to create sail dynamics which can provide an increment in thrust, increasing the boatspeed. In this study, we...

The completed work will provide a platform to model how sailor generated forces interact with the sailboat to affect boat speed. This will be used alongside realistic modelling of the wind and wave loadings to extend an existing time...

... Yacht races are won by good sailors racing fast boats. A good skipper takes decisions at key moments of the race based on the anticipated wind behavior and on his position on the racing area and with respect to the competitors. His aim is generally to complete the race before all his opponents...

The results strongly suggest that for this boat it is more efficient to reduce power by keeping the main sheeted hard and lowering the traveler than by keeping the traveler up and easing the sheet...

The results were found to agree with the hydrodynamic theory of boats with gybing foils; namely that they have lower drag for a given lift force developed to place aerodynamic forces in balance. The exact change in performance is not known and requires...
