Grob

I just did something a bit uncharacteristic of myself. I read the whole advertisement.

It has an impellor. They say there are 2 ways to mount it. The cheaper model (believe it or not) transmits the data (wireless) however the two parts must be max of 20 to 50 cm or 2.54 cm = 1 inch so 8 to 20 inches apart.

I have visions of the impellor getting smucked by something in the water or during beaching. Also anything like that will be affected by the flow around the boat as the water is probably accelerated as it is pushed aside by the hull.

Also you would need two as when you are flying a hull the other is 'blowin in the wind".

Maybe the answer is to get the CIA to track you on satellite. According to all the movies I have seen lately they can probably do that better than finding Osama.

I am a real serious guage weenie and would love to have some kind of guage for wind speed, water speed and depth of water. Unless you are blessed with a sailing buddy or a regular group of racing friends it is hard to guage the results of little tweaks etc on the speed of the boat.

I suspect GPS is the best bet.

The depth of water guage would of course have to be forward looking, as nothing is more useless than the depth of the rock you have just hit. I suspect some kind of fish finder might be the trick.

Now of course all of this gear would have to be cheap and ultra reliable.
