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. The forward and aft stringers,which the step is bolted to, are bulging. Tapping on them reveals a delamination inside. I am thinking this is caused by forces from the adjustable mast crushing the laminate wood inside. The bay this is in is too high to be caused by water intrusion. Anyone else experiencing this? The plan is to drill holes and inject epoxy, then bolt on a suupport piece of 1/2" aluminum across the face, bolted into the solid parts of the stringer. Any input is welcome.

Re: Stus-List Mast step stringers
Hello Brian, I would be very surprised to find there was any wood inside the 'stringers' on a C&C 37/40. There is no mention of wood used in any part of this boat's construction anywhere (except in the sole, in bulkheads and cabinetry) in any documents I have see for these hulls. I was sure the `stringers` were either completely hollow or there was perhaps foam inside, but only to hold their shape while they are tabbbed to the hull on initial construction. One `stringer` just aft of the two that support the mast step, has a large hole drilled in the top to access a keel bolt. It is completely hollow. Here is a link to the construction drawing for that hull: Here: https://drive.google.com/file/d/0B7X4Y5iVFYAKYTJxRDJBc3BvLWM/ view?usp=sharing and here: https://drive.google.com/file/d/0B7X4Y5iVFYAKcDd4ZlhWNGZzdmM/ view?usp=sharing Ken H.

Part 2 Hi Brian, The 'stringers' you refer to are the Structural Floors I think. Those drawings can be downloaded from the links provided. They are big, about 3' by 4' so it is best to download them and view them in a pdf viewer that will let you zoom way in. There is a detail on those drawings as follows: STRUCTURAL FLOORS 1. 2 LAYERS KEVLAR HYBRID 2. 1 LAYER KEVLAR HYBRID ON TOP ONLY 3. 3 LAYERS OF 18oz./1oz.

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? My concern is that they are bulging. I take it yours don't have the bulging issue? Any thoughts on injecting epoxy?

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
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.
