I just read Nigel Calder’s article on the costs of generating energy (“The Cost of Energy,” Dec. 2012) and found it fascinating. I understand there is a high cost for generating energy at anchor by running an engine, but is there an additional cost to generating energy while underway? If my engine is running the alternator to recharge the batteries, as well as moving the boat, surely it must add to the load and increase my fuel consumption. Is the increase significant, miniscule or somewhere in between?
My sailing buddy and I are thinking about moving to a bigger boat. I now have a 31ft Pearson with a full-batten main. It is a reasonably high-performance boat, and I love to sail it. My buddy wants to go to an in-mast furling mainsail. I would like some information on how much performance is lost when switching from a full-batten to in-mast main.
I'm trying to figure out why my paddlewheel knot log is registering incorrectly. The plug is clean, and the wheel turns freely. Yesterday my GPS showed my speed over the ground was 5 to 7 knots, and the speedo registered 0 to 0.8 knot. It does this periodically to irritate me.
