Regarding the Velocitek.  How easy is it to eye up the true wind direction when setting the upwind reference point ?  Stikes me that one could be quite a lot out.  Is it better to sail more than the suggested 75 m to minimise the error ?

If the race course is a bit "off", ie. not true upwind downwind, is it better to use the windward mark as the upwind ref point ?

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.

Here is a replay of the recent Msuto Skiff open at Stokes Bay.

3 races tracked of 2 boats (mine & Sten).

Quite intersting to see just how shifty it was

 NICE ONE. Good to watch,

ps what happened up the first beat looking good then stopped, large wave,hole or rig ?sorry to ask

 Chris

err got the answer now ,musto site. It looked like Guest#260 was going to come up top trumps of the pin but a wind hole seemed to swallow half the fleet that were further to leeward allowing Richard Stenhouse.

sten missed that hole even pointed higher ? Good job no voice recording then

As per the description on the report is was very shifty & holey. I thought I was going to lead by a huge margin 2/3rds of the way up the beat then I just hit a huge hole whilst those above lifted and had more presure.

As you watch the tracks you can see speed and heading changing huge amounts. This is what makes the GPS tracking very interesting for post race analysis and adds to the report.

 It is nice to see the tacking angles upwind and interesting to see the angles downwind. near the same. good software as well. garda should be good to see if all take part with gps. will the sailing instructions have to be worded to ban some of the on water track functions of my foretrek or will they let it go? . im not going just asking as gps is growing now.

Chris

The SI's are very open - it's a bit experimental but we are an innovative class and everyone is quite relaxed about it.

If you can fiddle with your GPS functions and compete in a MPS in Garda conditions that would be quite impressive.

I just use it as a speedo and to log tracks.

Hello,

Is the Velocitek S10 still the gadget of choice?  I'm thinking of a Christmas pressie (already!) - is this the speedo/GPS you would advise, or is there something else now?

Thanks.

There is the new SC-1 from Velocitek which is an excellent device in terms of existing functionality & extensibility but I think its a little too big for dinghies / skiffs with too many things going on. S10 is simple and gets the job done if all you wish for is a simple speedo & track storage with some VMG indication. Cheers
