RedCloud has Steel punching and cement for ballast in her keel now.

Most corrision on steel boats is from the inside out. Some people think
having air flow preserves the hull and use pegboards and stripping and
such for interior bulkheads. I don't believe it, as you know when warm
interior air hits the cold steel it's going to sweat. I have 2 inches
of insulation with to vapor barriers and a foil thermal backing, all
taped and sealed behind the mahogany and fgb. No sweating inside
redcloud except on the overhead escape hatch glass, It drips like a
coffe maker on a cold day and must be cracked open a bit. I disagree
with Doug assertion that a board is only good for round the bouy
racing. He must be thinking of a dagger board not full keel board like
on RedCloud. Infact with the board down rounding the bouys would be
slower. The board all the way down is best to help head futher upwind
and I raise it up to 1/3 down on a downwind run shifting the load aft
like the feather of an arrow keepin her straiter.

Umm, no, I was thinking of a big heavy full keeled boat like
Oriole.

Centerboards were common on the large racing schooners &
cutters up to the 1930s. These boats had quite a bit of
salient keel anyway, but the CB helped reduce leeway in
lighter winds. Some had two CBs to adjust the balance under
sail.

Really? In most CB boats, having the board down helps the
boat pivot in turns.

... The board all the way down is best to help head futher upwind

Do you mean to point higher or to reduce leeway?

and I raise it up to 1/3 down on a downwind run shifting the load aft

Why do you need it for that? Your boat has a skeg, right?
Try hauling it all the way up and heeling the boat to
windward like racers do. Faster & easier to steer unless the
wave action is getting up.


BTW Joe comparing your boat to Oriole is like comparing my
boat to the Queen Mary. Totally different scale.

really, she want to go straiter . My board starts 1/3 aft the bow and
drops 6' and the aft end is just forward the center cockpit

No a full keel with a cutout prop just forward the rudder like this

Ill give it a try.

My boat is almost 50% the size of Oriole . The Queen mary 19 time the
length of your trawler.

nautical triva bonus: Under the right condition you can pull the queen
mary with 8 pound test fishing line!

Your boat displaces 46 tons?

Only 8lbs resistance? Sure.

right around 35 tons empty. + 350 gals fuel + 175 gallons water+ 75
gallons waste

That's what I heard about the Queen Mary.

We have a show in the USA called Myth Buster.. Ill submit the question
and see if they can prove it.
I beleive it, Ive pushed a 600+ ton boat myself and made it move. 100
tons is a breeze.

No, I think the Queen Mary masses a little more than that

In the absence of any wind or water currents, the only
resistance is inertia. In theory, you could pull a tanker
with a single strand of fine blonde hair... you'd just have
to start real slow.

OTOH little gust of wind and you're SOL.

Anyway, the board has been gone for 80 years or so and she won the 2002
Vic-Maui. Nuff said!
