I have been sailing a 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.pb
