Sail Rocket have just hit 33 knots in 16 knots of wind, which is pretty impressive stuff.   However......  Crossbow reached 36 knots in 1980 and Yellow Pages record of 46.52 knots ( in 19 knots of wind ! )  stood for years until recently topped by a board.   There are plenty of speed experts on this forum, so my question is, do we think Sail Rocket will crack the 50 knot barrier ?

My view is that control is an issue above 20 knots of wind, unless you have a board.  This alone will make the 50 knot + barrier a tough one.  Therefore, boat speed as a multiple of wind speed becomes the key factor, ie efficiency.

Of course, if you can control the beast, then higher wind speeds are an option - Moths even top 26 knots conforming to their class rules !

Several quite different types of craft have pegged out in the high 40s... That's where you start getting badly into cavitation problems. That seems to me to be the big problem area.

Honestly, Sailrocket is an amazing craft but seems too have huge conception and control issues.

I would be more confident in the Hydroptere project.

This record concept has a huge 20 year history but seems to be currently at its top level in strenght, speed capacity, control ...

They manage in their first trials after refit to reach 45 + knts

The most likely is of course Cunningham's team, but they need to be able to overcome their chronic money problems, especially as their current venue seems to have gone light airs on them. They'd have been there years ago with the Hydroptere budget...

And of course Crossbow has lead the way for a thousand innovations into the sailing world - offset hulls are all the rage now
