[Public-List] Stern squat.

[Mike Lehman]

On the Alberg 30 the mast should be as far forward as possible. I have even trimmed the washers on the bolts to get the mast a bit more forward. It helps with trim and also helps sailing performance by reducing weather helm. The mast should be straight with no rake. Once the mast is "in column" and the shrouds are properly tensioned, tighten the forward lowers to put a slight amount of pre-bend in the mast. The forward lowers should have the most tension of all the shrouds.

The lazarett should be empty or only used for light weight items. It is unsupported weight since it is in the overhang. Keep weight to the center of the boat and avoid weight in the ends. This reduces hobby horsing.

The Alberg always sits a bit lower in the stern but there are things you can do to reduce that.

Also...what is your hull number? The very early boats we 460 pounds under balasted and additional ballast was needed to make them conform to class rules.

Hope this helps.

Hi all,
As I finish up some projects and spend more time actually relaxing on the boat I'm noticing some things that bug me that I would like to fix soon.   One of the biggest is the squat at the stern.  While I do need to empty the aft lockers, and currently have nothing up front, it seems to me that it squats a bit even when totally empty.  One thing I have noticed is that the mast is slid as far it will go aft on it's bolts.  Could I move it forward?

Has anybody added permanent weight up forward?  I have a Yanmar 2GM20F, and tank under the cockpit sole, as well as the port locker containing my house battery bank, even with empty lockers she sits a little bit heavy aft.
I'm thinking either poured in place concrete(broken up into smaller sections with 3/8$ foam, with a hard plastic layer on top of 1/2" closed cell foam to make it easy to remove if needed, and to protect the hull, or lead(shot in bags).

I'd like to get the bow down a couple inches, it's not the end of the world if I can't but it does bug me a fair bit.


Thanks

Jeremy
