2562RE: [Weta-Trimarans] DB lift discussion
- Aug 3, 2011Davo was talking about the "feeling" of lift, and I know what just he means.
The boat is a joy to sail upwind.. It lifts your heart!
The effect of the bow lifting out of the water when sail fast is caused by
the rocker, or upward curve, in the main hull. The flow of water under the
aft part of the hull sucks the stern down. This feature adds wave drag, but
it is very helpful when sailing downwind, when you want to keep the bows
from digging in. Also, the floats are narrower at the back than at the
front, so when the boat is pressed hard, the stern goes down more than the
bow. Both of these are design features that make the boat easy and
forgiving to sail, but they do limit the top speed.
