Back to the original question. When do you motor sail? In my case when the wind
drops to between about 5-10 knots. Less than 5 the sails
come down. More than 10 the motor goes off unless particular circumstances prevail. In the 5-10 not range consider a a series of wind quadrants and where you are heading. First is going to windward (+/-45 deg from the wind). ie you are going to windward. Drop the sails
and motor, its quicker. Second two quadrants +/-45 deg to +/-135 deg. Trim the sails and motor sail. There will be a speed increase or fuel economy gain. Fourth quadrant +135 to -135 deg ie downwind. Drop the sails as they will add nothing and flop around and slat annoyingly. The exception to above is when going to windward in >10 knots but in the confines of a narrow channel. The motor will enable you to pinch up to round channel markers and make tacking much easier as you can motor glide through a nice big arc
to wind at tighter tacking angles. By pinching you will drop boatspeed considerably but your VMG will be significantly improved.
