Flying Scot Rudder Fitting

[sailpb]

I have been sailing a Flying Scot for the past couple of months.

Today I went to sail and the upper transom rudder fitting was separated from the hull.

Questions are:

1) What are the appropriate bolt sizes?

2) What, exactly, are the bolts screwing in to? In other words - I see from the outside - the four holes for the fitting - but I'm concerned that the 'female' part - where the bolt goes in - might be stripped out. This is why I'm wondering what the bolts might be screwing in to.

Any further detail on this topic would be greatly appreciated.

Thanks.
