T&T: Anti Rolling Chalks

[Ron Rogers]

An owner of a Willard 40 full-displacement trawler had these installed and
is very happy with the result. In his case, the yard (Eastern Shore of
Maryland) designed and installed them. Most Defever designs have hard chines
aft, I thought. If so in your case, this might complicate picking their
location and design.

Subject: T&T: Anti Rolling Chalks

We have a 45' Defever pilot house that we enjoy very much. The one down
side is the rolling of the displacement hull when we are off shore in
the Pacific North West. I recently visited with a commercial fisherman
friend who operates a 60' steel trawler. He installed "anti rolling
chalks" of approximately 20' in length that stick out and 18" to 24"
inches from the hull. He has had good luck with these especially when
traveling off shore from Oregon to Alaska.



Dose anyone on the list have experience or knowledge of this type of
stabilization?
