Even the best sailboat cannot sail much closer than 45 degrees to the wind so this means at least 1/4 of the time you cannot sail directly toward your destination (2*45 =90 which is 1/4 of 360). On a loaded cruising boat, you will be lucky to get to within 55 degrees of the wind so this eliminates 110 out of 360 degrees or 30%. Where I live, NO wind at least 1/2 the time leaving only 35% of the time you can sail toward your destination. About half the time while trying to cruise, you get short of time so you end up motoring directly toward your destination getting you down to 17.5% of the time you can sail directly toward your destination. Around here, roughly 30% of the time the widn is blowing, it is a thunderstorm or tropical storm getting you down to somewhere between 10 -13% of the time you can sail toward your destination. This is why cruising sailboats need adequate engines. Interesting numbers. Of course, out here the wind is pretty high I think. By adequate... what do you mean? It needs to power the boat in most conditions, but if you're offshore and there's wind, you're likely sailing right? I can see needing something adequate in the bay or on the coast. The link I found said the boat had a 50hp, which seems pretty good for a 42' boat. Perhaps fuel capacity is also an important issue... Perhaps? Well, again, if you're sailing and mostly relying on the wind, then the only time you need the engine is in/out of a harbor or charging batteries (and perhaps a couple of other uses like refridgeration). Seems to me if you're conservative about how you use the engine, then it might not be such a big deal. -- Nom=de=Plume |
