Kevin; The mast wedges on my 1976 38 mk2 are intended to be put in from the top of the mast collar I believe. At least that is the way that they have been installed since I bought the boat in 2003. The wedges are about the dimensions that you cite, but have a "lip" about 1/2" tall that sticks up from the non-tapered end of the wedge and rests on the top edge of the mast collar (without protruding outside of it) to keep them from sliding down. They are thick enough that the last two or three to be inserted need to be tapped in with a hammer - tapped not driven, so the fit is snug but not what I would term tight or an interference fit.
I've thought about going the Spartite route. If I pulled my mast every year or so, as folks in some areas do, I'd go with Spartite. But I've only had the mast out when I first bought the boat in 2003 for wiring and new instruments, and when I rerigged in about 2010, so it doesn't seem worth the effort to change now. When I rebuilt the 27" A&H foredeck hatch several years ago, I went to a local glass shop to obtain the new lens. The shop stocked cast acrylic in 1/4" thickness for use in storm doors and windows. I'm told that most do. They had to order the material for my hatch because it is quite thick (3/8, 7/16, or 1/2", I can't recall exactly which) and I wanted a particularly dark tint. They took my old hatch lens and duplicated it ... Including machining in the recesses for the seals around the holes where the shaft of the hatch dogs/knobs go through the lens and the holes in the corners that have the retaining screws used to hold the lens in place while the sealant cures. I was frankly surprised at the reasonable cost (maybe $100-150, but I can't find the receipt) and there is no way I could have machined the various holes and seal recessed with the same accuracy. The hardest part of the job turned out to be getting the old silicone the PO had tried to use to seal the hatch leak out of the frame so the Sika 295 sealant recommended by the list would bond to the frame as well as the new lens.

First - mast wedges The boat came with about 3 or 4 wooden wedges about 1” x 2” x 4” that were wedged between the mast and the mast collar where it went through the deck. They were falling out most of the season. I am told that the original design had 4 wooden wedges that countered the mast to fill in the entire 360degrees around the mast. Is that true? What is a best way to replace these - Spartite ? Second - hatch lens replacement The V-berth hatch lens was cracked and leaking last season. I have removed the lens and plan to replace it myself. Hoping that the supplier can cut the new one to shape using the old as a blank, or I have access to a bandsaw to do that part of the job. What’s the best material for this - Acrylic? Any advice from others who have done this job before? thanks Kevin Kevin Deluzio 1980 C&C 30 Kingston, ON, _______________________________________________ This list is supported by the generous donations of our members.
