1. So from your observation the HT's wave piercing bows do not reduce pitching?
(I thought that was what all the hype/design was about?)
(Maybe the pitching is from the difference of a 18' boat vs a 20' boat,
where shorter boats pitch more?)

2. Upwind did the HT lack the power to punch though waves/chop
or lack of accelleration in that condition.
Which do think slowed the HT more in waves or chop,
lack of a jib? or hull shape? mainsail to flat? pointing to high?

Reaching I have no comment.

3. Downwind, how was the HT downwind compared to the others?

Thank you in advance.
