Lodesman: Yes, 80 knots is a bit fast for my boat so as you say, it is not much use. However, my dinghy
does at least that so it may be useful there, except at that speed I am too busy on the oars to be mucking around with a slide rule
thingo. Thanks for the tutorial.
S/V Alchemy: Unfortunately, this thing I have has no plotter function, I can't use it on paper maps. It only does slide rule sort of stuff, would have been good back in the days when ya had to figure it all out in ya head
GordMay: It looks exactly like the Kane one. Following the link you gave, I found the manual for it and if I was really keen I could learn how to use it - wow! To use it properly I would need to have a plane . . . . oh, and a pilot's license
Four winds: Amazing that there was one on your boat. Maybe there is some way they can be applied to sailing. For me, I think I would prefer to use a plotter like S/V Alchemy showed or similar or the GPS
which came with the boat which does show projected path. That projected path I have found to be very useful ever since I was sailing upwind as much as possible to get around a serious rocky point but the GPS projected path had me hitting the end of it. Until I saw that, I did not realise I was slipping as far sidewards as what I was.
