Either the wind is from the wrong direction, too weak or too strong. I thought most sailboats spend more than 90% of their time sitting in a berth or anchored. ![]() Why would you need to run the engine offshore when there's lots of wind? Seems like it wouldn't help that much. I can understand needing to get away from a shoreline, but in the middle of an ocean? If it's really that bad, wouldn't you want to try and slow the boat? I saw parachutes for this at the boat show. The average boat does spend well over 90% of its time at the dock but I'm talking about percentage of the time *underway*, i.e., not at the dock or anchored. When trying to get from point A to point B (as opposed to day sailing), the wind is frequently from an unfavoravle direction, too weak, or too strong for the boat/crew to handle. As a result the engine gets used a *lot* more than you might think. Ok, but that didn't really answer my question... I imagine it does get used quite a bit, but it doesn't seem logical to try and make progress against high winds when sails are available. I suppose if they were damaged, then sure. It is also important to understand that the *average* cruising sailboat does not cross oceans or run offshore for large distance. Probably less than 1% do that kind of sailing although we see a lot of them down here in the Caribbean. Many, but not all, of the ocean crossers look like they've been through a war. Right... I get that. I'm thinking most of our time away would be cruising in the Sea of Cortez and perhaps down further in Mex. On a different topic, most cruising sailboats do not have a standalone generator until well up into the mid 40 ft range. Instead they use the main engine/alternator to charge batteries, etc. This in turn causes a lot of extra wear and tear, sometimes leading to premature engine failure. The stories about engine problems on sailboats go on and on, and in my experience most are true. They are frequently located in difficult, cramped areas which leads to a lot of deferred maintenance. This is compounded by the mindset of many, but not all, sailboat owners to leave well enough alone as long as the engine still runs (benign neglect). It is rare to find a used sailboat where the engine and associated drive train are still in top condition. We were looking at something similar to this boat: http://tinyurl.com/yyoc997 It has a "genset" which I think is like a distinct generator. It's a 42'. I think maintenance is certainly important. I take my car in regularly. Of course, if you're away from civilization for a long period, you'd have to check it yourself and be thorough. I suppose some things are not really fixable without a boat shop, but that's true for cars too. Why would charging a battery cause engine problems? We were talking to a diesel mechanic a few weeks ago (interviewing him in case we found a boat and wanted his opinion about an engine), and he said that diesels like to be run hard, so I could see if you're just charging batteries without really "using" the engine to move the boat that wouldn't be running it hard. But, why couldn't you just put the thing in gear and push the boat while you charge the batteries? That would seem to solve the problem. -- Nom=de=Plume |
