Rough water skiing

How fast do you think the jetski in this clip is travelling and what do you think the wind speed / sea state is? It gets a bit 'samey' so just watch between 01:00 and 02:00. These guys jetskied from Scarpa Flow to Monaco via Biscay and Gibralter. Hard Core, especially at 01:28!

My Beaufort scale says it's 'mental'. Which is somewhere between a 6 and a 7 based on the streaking crests of the waves. Speed could be 10 or 15 knots I suppose but that's just a total guess having never driven a jet ski in those conditions. Don't tell me you're still thinking of getting one?

I agree with Erin. They're working a shore wave, which makes it look worse. No speed.

Agree, force 6 based on the small crests, so wind speeds around 28mph/42kmh. Jetski is probably doing less than you'd think, 15mph or so. The camera being so close to the water and jumping the waves a little is deceptive.

Perfect conditions for wave jumping , a bit of wind over tide with the nose trimmed up & away you go! Roll on winter & big seas.

Completely overcooks it at 1.31. Wonder the lead driver didn't break his nose or take out his front teeth as a result. Loads of streaming white horses, so probably blowing F6/7 with 1.5 wave heights. Wouldn't like to hazard a guess at speed, but not as fast as you think.

As a PWC Trainer I have total respect for the skill and cahooneys of those 3 skiers and trust me their average speed is more than 15 knots

I would say that in some parts he is hitting 35-40 mph in short bursts.
