I got a surprise today. I set speed genie to 27kts for speed instead of the normal for alphas at 10kts.
My understanding is that speed genie needs to be set to less than the minimum gybe speed, for an alpha to be calculated. So I was extremely surprised to see alpha results appearing, most of them less than 20kts.
Has anybody else seen this?
Have I had it wrong the whole time? Bit embarrassing if I have!
Mike, I've experienced the same, but they are only the odd random result and never any plus 20kt.
You haven't got it wrong. The only way to get consistent alpha results is to set your speed genie less than your lowest speed in the alpha

I have seen the same thing with the speed genie set at 25 kts ,the odd alpha perhaps only one or two per session will be displayed on the watch, usually around 18-20 kt alphas.
Also I have had a few cases even with the speed genie set to 10 kts when the watch fails to record an alpha. But they are later recognized by realspeed and KA72.
However the alphas that the watch does display are typically within 0.1 kt of the calculated results in Realspeed/KA72
Had an 8.28 knot alpha today on the watch with speed genie set to 12 knots. I think that was the only alpha the watch showed for the session. Actual best alpha was 13.47 knots (longboard session in marginal winds). FW V 1.2A0314B
I just got around to checking, I have Speed Genie set to 22 knots. Is the thinking that if I set it to 10 it will give me a better idea of how my corners are going while I'm on the water? I generally don't have a problem making the radius so I could try going a little wider.
Ok, I'm trying 10kt Speed Genie setting. All of my decent gybes had me no lower than 12. I just need more speed going in. I reckon I start losing speed as soon as I set up for the gybe.
Yep, I speed up as I go into the gybe too. I think I am slacking off a couple of hundred metres out. Sometimes I do a gybe that feels really good through the turn but the @500 is lame because I was only doing 23 knots at the start of the track. I reckon getting more feedback on the water will be a help, and hopefully the lower Speed Genie setting will have some more show up. I'm learning the speed sailing is about the wind, the water, the equipment, the technique as well as strategy. I guess that's why i'm enjoying it so much.
Strop tries to be bearing off flat out when he hits the start, then carry as much speed slightly upwind as he can for 225m, gybe and come out slightly downwind to get good acceleration, before heading back to the 50m separation point. He can judge distance really well, I need alpha markers to do this.
Hello, does anyone know how to set the speed to be constant. that does not mean jumping up and down so fast. With the Velocitek speed puck you can enter a delay in the measurement, can you do that with the GW 60 too ?, thank you for your answer. regards
I'm planning on getting back into GPS sailing, is the GW60 available from a friendly shop in Perth or is on line the go ?
I'm pretty good at breaking things and after reading some of the reviews would prefer to have the back up of a local retailer.
I've got a GT31 but it's in a box somewhere 
Thanks for that Firie,
That's just down the road from me, and they're on special :)
