You are sailing an ultra lightweight boat, with water
ballast, on the ocean.

Winds are light and you don't need to carry ballast
for righting moment.

Why would be a reason to carry sea water ballast
in these conditions? 2 pts

2 points to you.

momentum

Good question Oz. It would be upwind for the answer given
by BB--momentum.

I'll give you 1 point for being astute enough to realize that..

What point of sail?

To dampen the pitching of the hull, increase the water line and to keep
the hull on its' design lines

You haven't convinced me.

Weight in the bow when going downwind in light
air would reduce wetted surface. This could be
accompished by shifting other internal mass,
including crew weight forward, or even better, by
use of a swinging/canting keel.

Wetted surface can also be reduced by inducing heel.

I can see how punching through a contrary swell
would be improved with ballast, but this could
easily be accomplished with athwartships ballast
tanks.

The best place for ballast tanks is in the aft flared
section of the hull where it will exert the most
leverage, and heel can be controlled by choosing
which tank or tanks are filled.

I don't know of any boats with built-in bow ballast
tanks. Do you?

I didn't see any bow tanks in the specs.

All swiftships over 110 ft have bow ballast. Keep them from getting to
airborne.

They make one of the finest hulls, but as you can the the canooks
screwed this one up when they repowered it. It was a much better boat
with the triple 800HP MTU's. Typical cannoks!
