We restored a vacant old house in town and the owner turned it into a used bookstore. It was never planned to be profitable (thank god). It's a self serve bookstore normally with no clerk present: Leave your cash or check in the slot.
The above is todays truth. New books, many out of print...
You have Sail Power by Wallace Ross. That book changed how I trim sails and ultimately how I love to sail. I once took a North Sails Gofast weekend course. It was a crashing bore. Based nearly word for word on Sail Power, I already knew that by heart.
Me too,...on heaving to(both points). It's the term that is difficult, not the maneuver.
I find saying it this way is less awkward; 'After furling the mainsail, I rather enjoy just sitting while the boat is,... hove to'.
