Is there a way to get a hold of Russell?

I knew him from a long time ago.... and would like to get in touch with him

Cheers, Niki.

COOL!!!

The wind speed he is measuring is off the beam is true wind speed. To measure apparent wind speed this needs to be done directly off the bow in the direction of travel. The boat is sailing on a beam reach and not on a windward tack where true wind speed would need to be higher for 17 knots boat speed.

@crxmad No. The only way to _COMPUTE_ true wind speed is to measure apparent wind speed, apparent wind angle and boat speed. True wind speed cannot be measured directly, unless standing still.

I think you mean true wind speed. You can't sail 17 knots in an 10 knot apparent wind speed. It appears that you may not have possibly been holding your instrument in the correct direction to measure the apparent wind as apparent wind is always forward of the beam. The clip looks like your holding it directly off the beam. Your main sail's sheeting angle indicates your on a tight beam reach. is that correct?

[JaiGopal]

the instrument measures apparent wind speed

[kyledagg]

Only to people who know bugger all about sailing..... ie if you moving into a 10 knot breeze at 10 knots how much wind then would you feel on deck? 20 knots apparent wind, so the boat is creating wind by moving forward. The same thing is felt on a bicycle when pedalling into the wind. In this case more wind = faster boat speed.

[kyledagg]

Fair point, your quite correct.... my apologies.

[Ransomlikespie]

I rode on this boat. Quite the thrilling experience.

Thanks Russell.

[thefrozenhawaiian]

awesome, what kind of boat is this exactly

[hinahanta]

It is a "Proa"

[rickybearrt]

Fantastic boat ..... ghastly video. Who cares about that handheld gizmo. We want to see this AMAZING BOAT!!!!

[heinrich97]

Well, I care about both. Very interesting concept, but of course speed is big interest.
