PHRF Courses and Sailboat Design

Performance Handicap Racing Fleet (PHRF) race courses have transitioned from traditional Olympic triangular patterns to windward-leeward designs, emphasizing tactical skills, boat speed, and positioning. Random Leg courses, which offer varied angles and conditions, provide more balanced competition for different boat types.

Naval architecture has evolved to optimize boats for specific conditions, creating designs specialized for particular race formats, often favoring performance over versatility. Cruiser-racers and traditional cruising designs may struggle to compete on modern windward-leeward courses, prompting new classifications.

Centerboard Slot, Gybing board, Forward Rudder and Canard

The nature of  the Murrelet centerboard is not well understood. MacGregor Yachts states in the cruiser’s brochure that A long, thin airfoil is far more efficient than a short, wide one. This is why racing sailboat keels are deep, and why sailplane wings are long and thin. The relationship between the fore and aft width of the board…

Canting Keel, DSS and Dynamic Control

Canting Keel Centerboard, swing keel, or keel, new monohull sail boat purchasers should at least consider vessels like Sadlers, Potters, Etaps and MacGregors that have solid flotation. They should also choose thin rather than wide monohulls. The thinner the hull, the more it is like a log in that it is self righting and of…

Planing vs Displacement Sailing

There are four modes of sailing. Displacement mode, forced mode, planing, and the 4th mode. Obviously many ocean sailboats do not plane and hence there is no reason to learn sail planing techniques on those boats. In fact it is just the opposite. There are good reasons to learn how to prevent planing on displacement…
