I sailed the TriFoiler many times. I was able to peg the 40MPH speedo many times.

Takes off like a plane lifting off the runway. Gets to top speed very quickly.

Careful on the Gybes if you are not ready you will be SLAMMED into the side of the boat...ouch!

I have peaked (not buried) my 35 mph speedo as well.

I have had runs with seven or eight one mile long runs with full speed gybes without coming off the foils. Average speed 27 mph, peaks at 34 -35. Not bad, 7 miles in 15 minutes with a sailboat.

The speedo is within 1 mph of gps indicated speed above 15 mph. Below 15 mph it is quite jumpy probably from the turbulence and bubbles from main hull not fully lifted off.

Windsurfers may have an edge in all out competition , but certainly not the ones around here. I typically pass them with 5 to 10 mph edge when on foils.

What a fantastic boat. It really attracts a lot of questions.

I have updated some of the info on Wikepedia for the trifoiler and the Hobie 18 M.

There's probably a small range of conditions where a windsurfer is faster (I've GPS'd a max of 39mph and regularly hit 35mph), but the trifoiler wins hands down when it comes to ease of acheiving speed. Going really fast on a windsurfer is a lot of work.

And I gotta think that in any kind of course racing that a trifoiler would have the advantage of a windsurfer.

40 MPH sounds amazing. What wind speed did you do this in and were you sailing with reefed sails?

I have run the boat at 35 MPH four times so far this summer but not higher - it is a blast sailing this fast.

How do the TFs handle heavy chop and swells ?
I assume ocean sailing wouldn't be possible ?

Last summer the GPS recorded a max speed of 40.2 MPH through a gybe. It was the fastest I have had the boat up to yet and this was season two. My first summer I had it up to 35 MPH many times. What a machine.

As far as chop or waves is concerned the boat is reportedly good to about three feet after which the waves apparently hit the hull enough that there is too much drag to keep it above the water. It is also way harder to get the boat to rise on the foils in waves than it is in flat water.

Regards,

Dan

Swell is not bad as the waves are generally not too steep and the sensors can regulate boat height above the waves. I have had a couple experiences at 35mph wiht swells where I am nearly werightless in he cockpit as I go voer the top of a swell. A lot like a roller coaster doing dips. The sensors (little skis out front) combined with the foils are a mechanical control system that keeps the height of the hull boat above the water fixed.

Heavy chop is not a friend. If the wavefronts you are striking are steep enough AND you are going fast enough , you could stuff a sensor into a wave hard enough to cause the foil to dive too deep and the ama wil hit the water..... and suffer really sudden deceleration .... possibly even damaging the boat. I know of a case where this happened with lots of damage.

This scenario is easily avoided by being sensible about the conditions that your are sailing in. If you are suddenly caught by heavy chop, limiting your speed and/or altering the approach angle to the waves to run more parallel to them can minimize the effect.
