The following were posted on the Weta site, any comments, I have a feeling Daryl will have some info.

"I had to ask the question! I have seen comments about 16.8 being the fastest
recorded speed on a Weta. Given that they look fast on a reach, that would put
the max speed slower than a bunch of other monohulls. Even the Blaze has been
clocked at 18-20knots on a flat non tidal lake. There are plenty of videos of
wetas looking quick has anyone clocked any better when the tide was not a big
factor?"

"in my experience...
they are only 14' with relatively low volume and short ama's (by "balls to the
walls" tri standards anyway)
on a beam reach 14knots is about the best i can get, but that's in about 10
knots of wind!
to go faster you need to be sailing much deeper angles, say 130degrees, so the
bow buoyancy can help the leeward ama when needed. also have to be well hiked
well out the back corner to keep it on the plane
you'll need much more wind to make this work, say 20knts of wind to get 16knts
of boat speed?
after 20knts of wind you are pretty much well too much into survival mode to try
for max speed runs
eventually someone will crack the right combination of wind, water and sails and
bravery while carrying a gps that is switched on and recording a track that
exceeds 16.8knts
but it's a rare thing in the 14' world
don't think i've EVER seen an uploaded gps track of 16knts for a 14' sail boat
perhaps i should go trawl the I14 and B14 skiff forums:o)Â

let's say 130degree broad reach with 20knot winds may provide about 16kts boat
speed"
