Re: Stus-List Mast step Stringers
Mine had what looked like medium/high density filler laid under the step as a leveling agent. Some of this material was found in/under/around other areas but nothing in a manner which came close to filling the stringers. The original screw holes were drilled at a weird angle because the floor liner wouldn't allow a straight down approach. Since I cut back the floor liner to get the step out I now had access for a vertical approach. I used west systems six10 to fill all the old holes and finish/dress the step bed. I laid the step in place and squared it to the adjacent floor boards, marked my holes, Removed the step, drilled for the applicable lag bolts (3/8th IIRC), reset the step and then with a bit of tef-gel between the washers and the step installed the lad screws. It's not like there is a significant concern for the mast/step to lift off the bed. The screws act as much like an alignment pin as anything.

Re: Stus-List Mast step Stringers
I am just finishing the rebuild of the mast step on my 30-1. It was not high tech at all like the later boats, using cross-wise stringers made of plywood which had fiberglass on the top and sides but not on the bottom where the water gathers. After 36 years and a couple of repairs, they were soggy! Deciding that letting water sit in the deep part of the sump, where only a small bilge pump would fit and when clogged up with some gunk or pieces of delaminating plywood, would fail, requiring the removal of the mast to replace, I dumped three quarts of West epoxy down there to create a small slope from front to rear and get the water back into the area where an installed bilge pump is accessible. I did it in stages with slow hardener, which avoided the heat problem and then covered it with a layer of cloth/mat. Three new stringers, each made of two sandwiched ¾ inch UHMW (almost as hard as the red stuff, but easier to machine) now sit on top of that new sloped area to keep it dry. I put a piece of 2” PVC pipe around the one keel bolt to allow access. I hope it will outlive the rest of the boat.

Re: Stus-List Mast step Stringers
Thank you Ken.. Very helpful. I will take another look. I do have an access hole drilled thru one of the stringers to be able to torque one of the bolts, If I recall it is not hollow. There are also bilge drain holes from bay to bay, again they are not hollow. I agree the drawings show no material inside, but then what would the mast step plate be screwed to?

Stus-List Mast step stringers
1993 37/40. Redoing the rod rigging, mast is down. Removed the aluminum mast step to media blast and powder coat. There are three `stringers` the mast step sits on.
