Dagger board structure

[TAM]

Does anyone have pictures/drawings of he structure of the dagger board on the M? I'd like to add some additional weight and want to see what's in there before I start cutting/drilling.

For a second there I posted the structure of the daggerboard trunk...but have retracted it....

I realize now you're adding ballast to the daggerbosard itself. Many here have done it. But I have no pics of it. I'm not sure you have to cut into at all. I thought I recall some plugging the bottom and pouring in lead shot, mixed in epoxy resin, down from the existing hole in the top.

Here's a post with a photo of a broken one.

It's all fiberglass, and pretty much hollow except for a lengthwise structural feature.

I added a stainless steel pipe down the center of mine for strength and poured 55 lbs of molten lead shot in it for ballast.

I chewed up the bottom 8" on a submerged concrete pier last year (lake was down about 15 feet from normal.) Before I go to repair or build one from scratch... what is the price of a 26M daggerboard?

Daggerboard vs. swing-up centerboard ?

I have dragged my swing-up centerboard more than once in the shallows. Problem only to my pride, such as that is.

I had a neighbor at my previous marina lose the daggerboard out of his brand-new 26M - it just sorta slipped out.

Guess I'll stick with my

Hi,
You might not be happy with adding ballast to daggerboard. The board will bang around a lot, injure the trailing edge at the exit point of the trunk, not provide much extra righting at normal angles of heel. If you must do it: build a sleeve 18" tall around the daggerboard, use several sheets of wax paper and one thin card stock papre wrapped around the gaggerboard, make the casting, slide it around while not quite hard to make sure it will slide all the way uo and down, after fully cured, insert into trunk from bottom along with daggerboard from top, with a lot of resin/glass mix. During cure be sure to slide daggerboard up and down to make sure it didn't stick to sleeve. I did this to make the 600 lb keel for my black 26M.

How much weight has everyone added to their keel? We were out last week sailing about 60deg to the wind, 15kn. Heal was steady at 40deg. I'd like to reduce that to 25-30deg if possible. The engineer in me says do the math, but trial and error is fun sometimes too.

It sounds like you were carrying too much sail, were over sheeted, or both.
