Solstice Exceeds Theoretical Hull Speed at Antigua Classics

On April 18, 2010, SV Solstice (Cape George Cutter 31) officially raced “The Cannon” at the Antigua Classics, sailing 26 nautical miles in 198.3 minutes… a course requiring two jibes and one tack. Skippered by Captain Paul Exner, Solstice sustained 7.26 knots for (3hr : 18min : 20sec), beam-reaching off Antigua in 18-22 knots of True Wind… her boat speed exceeding the expected 7.03 knot Theoretical Hull Speed!

Theoretical Hull Speed = 1.34*SQRT(Load Water Line); where a longer LWL will sail faster than a shorter… used to approximate the efficient speed of a Displacement Hull.

Solstice’s LWL = 27.5’ … thus she was being sailed to an estimated waterline of 29.36’ in The Cannon race. As shown in the attached photo of Solstice in action during The Cannon, when heeled, her effective waterline length extends to the upper part of her transom.

Several people looked for Solstice on the dock after the race and made many positive comments about her speed and appearance; and a few said they’d jump ship and join Solstice’s crew if we’d have them!

Kind regards,

Captain Paul Exner
