Re: Electronics/instruments for lake sailing?
I just looked at your lake on Google earth. It looks quite irregular in shape, so I think you'll get some fluky winds..I don't think I'd spend a lot of money on electronic wind instruments.
Just sail the wind you've got.
I sailed on lake Tahoe once and the winds clocked on me every 5 or 10 minutes it seemed. But we had no where special to go..it was a blast.
Depth might be useful. I'd study the charts and see where the trouble spots are and see how easy they are to stay clear of. I used to lower my centerboard a foot or so..as kind of an early warning system. If I felt the centerboard bump, I stopped the boat, or turned. It didn't happen much, as you get to know where you can go.
What's the bottom? Rock? Mud?
You'll have a blast in that boat! I think all you need are sails.
