Velocitek S10

I use the foretrex 201 with the inbuilt battery, I takes about 20min to get the mean wind direction setting right. I set the the waypoint 60 miles away. I have to change this about 3 times in a 4 hour sail as the wind moves around.  The function Turn is very good in evaluating my angle from direct downwind,sailind dead downwind should read turn 0. Very pleased with it. it got smacked by the boom and survived. If you want to put it on the mast any gps with a large screen will do.  I use a garmin GPSmap 76CSx waterproof and floats, in a waterproof bag just in case.Very large display taped to mast.

 I find that the vmg drops when heading up before rising as my speed increases, also when slowly going lower the vmg rises before it drops when the speed drops. very hard to evaluate if the wind is not constant.

I find that pointing high and footing off in the rs600 gives the same vmg. but in large gusts it pays to foot. ?

After a month or two i think it will not be an advantage to have vmg but i still need a good stopwatch and compass, Have I got to pay £45 for a yellow stopwatch and drill holes in my mast for a compass when iv got the lot in my foretrex ? At the moment I only use record and stopwatch for racing as my yellow stopwatch came out of the case last week , in carsington somewhere.

Are we going to police these gps devices as it could be classed as cheating. I know the musto have allowed this for some events but are other classes going to let it go ?

After thinking about it the foretrak will always be banned as you could view  the track down the startline for midline sag . so  training only i think.

You have two external buttons. One for each end of the windward / leeward course. When you reach each mark you just touch the button. Or you can even do the setting on land. All it does is to store the compass heading between the two points you touch the buttons and then compute VMG using trigonometry. This is explained quite nicely in the user manual pdf which is on their web site. Hope this helps.

I had a look at their website -  can I ask how much they are.

(I couldn't find price-information),.

Certainly sound very interesting - was personally about to start looking into buying an etrex.

thanks

I've got a GPS in my phone that I use to record NMEA logs when I'm racing.

Then I've got a converter that plots the track into google earth - you can really see how well you were playing the shifts upwind!
