presto13031I made the Kessel Run in 10.8 parsecs on my Hobie 18.

OK, this just doesn't make sense, parsec is a measure of distance, so that would be like saying I just made a Taco Bell run in less than 5 miles. (which I did)

17 knots solo on my P19 with a 14.9 knot average over a one minute interval two months ago.

I have found that the top speed , as shown on the screen of the device, is always 1-2 greater than what the device actually calculates. I do not know why this is so, but it happens.
If you hook the GPS up to your computer & extract the data, you see this, every time.
I looked through a recent data log from the 5.0. GPS showed "max speed" as 20.5mph. It had logged 592 segments, that varied from 30 metres to several hundred metres. The highest one was 19.9mph, over 157 metres. I think that is fairly accurate, as one run remained at 19+ for nearly 6 kilometres,(I have the output on the screen set to show mph, but the device internally logs everything in metric units).
There is an earlier post regarding an H16 "pushed well past the 20 mark."
I do not believe that.
It is well known in the tuner & racing camps that there is no substitute for horsepower. In order to go faster you need more power, lots more. It is not a linear graph. With wheeled vehicle, it doesn't take that many horses to push a light car to 100 mph. It takes hundreds of HP to double that speed to 200mph.
The situation with a boat is worse, due to the density of water creating much more resistance than the rolling resistance of tires. This is the reason it is easy to go 18mph in a Cat, but breaking 20 becomes problematic. We all talk about "powerful" sail plans, but in reality they don't generate very much, limiting speeds to around 20mph in conventional Cats. My 20' Mystere could do it in rougher water than the 5.0, but I never did get it to make 22. The oft repeated phrase that Tornado's are theoretically capable of 35 kts is a pipe dream.
The move to foiling boats removes much of the drag, hence the speed gains.

Mischa hit 30 MPH in the 2010 Tybee 500 on a Hobie Wildcat. In the same conditions, we touched 27 MPH. These are not B.S speeds; the 60nm course was covered in 2h30m by the lead pack, so an average speed of 24 knots was maintained by the highly experienced N20 and F18 sailors at the front of the fleet.

Definitely sustained speeds over 25 kts are tough, really tough to maintain on these boats. We were out two weekends ago in 25 ktsg27kts on the Infusion Mk.2. It was cold with no chase boat in the water and only one other boat out with us, with less experience in big breeze than us. We did not push the boat hard, didn't really need to throttle back but the puffs were large and we were still minutes ahead of boat #2, so pushing harder wasn't prudent. I'd be surprised if we hit 22-23 kts on that day. Felt more like 19 kts max. We were fully depowered and full airborne with just the rudders and back 4" of the leeward transom in the water upwind in one puff over 30 kts. That was in flat water.

That's the reality-some conditions really demand throttling back (see Spindrift 2 in current Route du Rhum) on these powerful boats. Semi-Foiling and full foiling lets you push harder in some conditions and maintain higher averages.

Well, if I utilize the hydrodynamic, magnum devices on my Aqua Cat, she blows everything out of the lake. 35...40 knots?

I believe Mr Aqua Cat Thunder is talking about his blow-up motor boat.

Max 17.7 mph as my crew calls out speed from my Garmin Fenix. I'm slow but having fun.

optikidI would say that i can hit about 100mph with my opti
I think on a good day i can hit about 10mph if im lucky and in ideal perfect conditions.

This is my H16.

When it is blowing i can hold 1-2 minute averages of 20mph+ pretty easy. i have several downwind runs rocking a steady 23-24mph It would be REALLY tough to hold onto 25+ for any length of time.

Spiked to 26.4mph..

Mystere Catamarans just tested the new foiling version of their Espadon last month near Montreal. They didn't report on speed (tested in 10-15 kts of wind), but I'm sure by next summer they'll have set the bar higher for everyone.
