HotSail GPS Speed rigging tips

Need some photos of the sail rigged - could be various issues if tuned correctly on the matching mast camber spacers may need removing you should be able to move the cam a bit with your hand if spacing is correct

You might want to email Jeff or even just call (1 808 893 0001). He's helpful and knowledgeable and will probably be able to say whether it's a downhaul issue, a spacing issue which would require grinding down the cam a little, or just a mast compatibility issue too grave to be worth struggling with. I'd rig it first so you can send pix.

What Jetlag said. That said... I got mine to rig pretty well on my Chinook mast, but they also lean towards the Flextop side of the constant curve spectrum. Cam spacers are the first thing I would check.

What's a cam spacer? Please excuse this wave sailor ignorance ??

Cam spacers modify how strongly the cam presses against the mast, and operate independently from batten tension. They are little rectangular plastic washers which sit on the outside of the webbing which receives the front of the batten. With the sail downhauled and the batten tensioned, you should be able to just pinch a little fabric away from the mast just in front of the cam. If you can pinch a lot of fabric you need more pressure so you'd add a spacer or two. If the sleeve is drum-tight there's too much pressure and you'd either remove a spacer or if there's no spacer installed you'd grind away a little of the inside of the cam.

It sounds like you may have too much pressure although poor rotation can result from too little as well. If the cam rotates with a big bang if you push (or kick) it - that's often too much pressure.

HI Anyone got one of the Hotsail GPS Speeds? Rigged for first time and finally got rigged after an hour but one of the cams just wouldnt flip. I had to hand push it no matter how hard my gybe flip was. Any tips on rigging ang adjustments would be great. I dont sail flat water a lot so only do it to see how fast I can go so this sail is just a cheap speed option 6.0m but frustrating day on the water. Only managed 29.4knots too which was disappointing.

JB, you will definitely need a flex top mast mate. These sails do not work on anything else.
