A heady tale.
I was beating down the River Blackwater in a comfortable breeze at around 6mph, my chart plotter being calibrated in mph, when one of the crew had to visit the heads. He is a chunky chappy weighing in at over 16 stone. As he squatted down the boat immediately increased speed to 7.5+ mph steady and she handled better so trim is an important factor, as John said.I just feel I cannot ask my guests to take turns and sit in the heads while I beat into the wind.
Fastest I ever registered was 11.5 mph but that was surfing down a wave around the Needles.
In light winds loosen the sails to make them baggy and tiptoe about as you don't want to knock what little wind their is out of the sails.
It is probably down to me but I find Sowenna is not the best at beating into the wind.
