T&T: Anti Rolling Chalks

[Bob Salmons]

I put roll chocks on my Willard 40, Veronica.  They work like a charm,
even at anchor.  If you are handy with fiberglass, you could do it
yourself.  Oboard Veronica, they are 1/3 LWL, centered  equal distance
fore and aft.  They are made out of two layers of 3/4 marine ply,
about 20 inches wide.  They are angled fore and aft so as to shed crab
pot bouys whether goin ahead or astern.  They are not throughbolted,
but glassed in place.  They are at a slight angle to the the waterline
so as to conform to waterflow in that area of the hull at crusise
speed.  All edges are radiused.  They are mounted at a 45 degree angle
low enough that they don't stick out beyond the curvature of the hull
when observed from above.   I will pull togerther some photos and post
them on Picassa.

As near as I can tell, most any yard that works on fishing boats could
do it for you for approx $10,000.  It works so well, the dog doesn't
get seasick.  I think it works by trapping water between the keel and
the chock, called bilge keels by the educated, acting as a shock
absorber to dampen out rolling energy.  Think of it as a way of
increasing displasement, but not weight.

I'll be back with a link to some pictures.  Of all the things I have
done to Veronica, this is by far the single best, greatest
improvement.  40 knots of wind in a Chesapeake chop is a wlak in the
park.

Do it!!
