First off I must advise I am friends with the importer of Hot Sails Maui (HSM). I've known Jon or known of Jon through his family for many years. He is a mad keen windsurfer and is keen for the sport to grow. Plus he is a Seabreeze sponsor.
HSM says its their no cam slalom and freeride sail with outstanding speed, control and ease of use with exceptional value for money.
Last summer I demoed the 6.6m Speed Demon at Kyeemagh in a seabreeze of around 20 knots. I really enjoyed using the sail. It felt fast, stable and easy to use. I was never totally comfortable with my older sails. I don't think this was the fault of the sails though. The recommended mast for these sails was never used, thus they probably never rigged as they were designed to. In comparison the Speed Demon felt stable and slippery through the wind.
After the demo and with both sails and masts for sale at very reasonable prices I purchased two Speed Demons and the recommended HSM mast.
The sails appear to be well built with for example some form of leather material in hard wearing areas such as batten pocket tips and the mast tip. The sail package comes with some goodies such as an extra batten bolt, rigging instructions and some stickers. One aspect I miss is a little hole in the integrate mast base cover to thread an uphaul through. Overall the sails appear to be very well made.
I decided to buy the recommended mast for the two sails I bought, the HSM Hot Rod 460cm 97% carbon content mast. This is an RDM mast, the first I've had so I needed a new mast base. Jon sold me a Chinook carbon fibre mast extension, again for a very reasonable cost.
With the correct mast and base I found the sails rigs very well. With the recommend downhaul the leach of the sail progressively falls from the top of the sail. The sail fills out at the bottom creating a bit of draft there. These dodgy photos illustrate this.
The demo greatly impressed me with the performance. Since owning the two sails I am still enjoying sailing them. They are quick to get on the plane. They seem to have good top end speed. I'm able to keep up with some fast sailors since using the Speed Demons. Being very light in the hands they are easy to flip when gybing. They are easy to fly when waterstarting. With the GPS I've had the 7.3m up to about 27 knots and the 6.6m up to about 29 knots. I'm not the fastest sailor in the world so those speeds are good for me. Until recently I was lucky to get over 26 knots for a 2 second average.
The sails have a definite body shape around the boom when rigged. The result of this shape is stable draft. They give a positive thud when flipping the sail in the gybes. That is pretty impressive with a no cam sail. The battens seem up to the job as the sail feels extremely good when overpowered and just wants to keep going. I've had the 6.6m up when other sailors are on 5m sails or less.
To my eye the Speed Demons appear to be rather plain. There are large monofilm panels and few seems. When I first saw a Speed Demon I thought they looked quite simple compared to other sails. However after having them for a while I appreciate what the designer has done, creating a well shaped sail without unnecessary complex design. Other windsurfers think the sails look good out on the water.
I'm happy with the sails. They are excellent value for money selling from about $900 with the recommended mast. I plan to extend my quiver of Speed Demons in the future. I'd like to go up to about 8m and down to the 5m. We have had quite strong westerlies this autumn where a smaller sail would have been more comfortable.
Here is a short video of the 6.6m sail in action at Canton Beach NSW. The wind was a typical westerly, up to over 20 knots and down to around 10.
So I'm really happy with the Speed Demons. They make windsurfing a joy.
