Wow Bill, 22 knots boat speed on an older 36 foot cruising cat!!!!!!!! With those kinds of numbers I have a serious case of performance envy!
On my Solaris Sunstream 40, performance is rather pedestrian. Loaded with extensive stores, full tanks
, various tools (including power tools - I am in the process of interior
renovations) and with an old headsail (the main and staysail are new, however):
Under 5 knots of wind speed true, I motor
With wind speeds at 6 knots true, so long as the water
is pretty calm, she will hit about 2.5 knots on a reach (but you had better not head
her up above 60 degrees true).
At 12 knots, 5.2 knots;
At 16 knots, 7.8 knots (Above 16 knots, I typically furl the staysail)
At 18 knots, 8.0 knots
At 20 knots, 8.8 knots
At 22 knots, 9.2 knots (Above 22 knots, I typically put in the first reef in the main).
Thththththaaats all, folks! Yes, I need to replace the headsail and I have considered folding props. Even still, my goal
is for 1/2 wind speed, when fully loaded.
