Interesting shot of state of the art yacht design, these guys spend millions to go faster than the oposition.
Look at the very fine displacement entry, flatening out to a planing stern, they fly down wind.
Also interesting to note the forward rudder. The ballast on the canting keel is slung on such a fine keel, lateral resistance is gained from the forward rudder. This rudder also turns opposite to the stern rudder for tight turns.


The 20' & 16' boards here have similar hulls

The recent 12'6 is even more Wild Oats like with a broard stern.

Hey... Wild Oats have copied your design Dean..

That's the first flat bottomed racing yacht that I've ever seen.. I wonder if it gets on the plain.?

Mate....These machines plain like nothing else....the 24 hour mono hull speed record is 25 knts average....so you could imagine the top speed they hit.
Search Volvo Ocean race & look at some vid...wild speed & days on end.

Fantastic video Dean, I knew they went fast but actually seeing footage of them doing it is amazing.

Volvo Open 70's have been known to hit 40knts......now thats planing
So what can we learn from these wild down wind machines? at that speed they are spearing into the back of large waves.....no planing bow with nose rocker....all flat with fine displacement bow.
