Typhoon: Deck Failure @ the Chain Plate

[Robert fisher]

My 1975 Typhoon has developed deck failure inboard of the chain plate
ie: a 6 inch crack running fore to aft and a smaller 2 inch crack running side to side. I have read the posts on this problem which seems to be common in these boats. The approach is to drill a series of small holes to expose the core and after cleaning
out any rotted (water damaged balsa) and allowing time for drying to fill the affected area with epoxy and reseal the deck.
My questions; will the effectiveness of the chain plate be enhanced or reduced by this proceedure assuming repairs are done properly.
Most likely this problem was brought about by (not under my ownership) by over tensioning of the rig. Is it necessary to attempt resetting the trunk to the original level or should I just drill and fill as needed? Any response from someone who has experienced and solved this problem would be greatly. What were your long term results?

Robert,

My questions; will the effectiveness of the chain plate be enhanced or reduced by this proceedure assuming repairs are done properly.

I would recommend a mast support post in the cabin to take the stress off this area of the deck.

My Typhoon, Blue Diamond, is also on Cayuga lake, on a mooring just north of Sheldrake point. I have no deck cracks, but I did put in a mast post as a preventative measure. Drop me an email if you'd like to have a look at it.

Let's hope your rot is not too extensive...

Regards,
Richard.
