cant you just make what you need or get someone to make the bits for you.
Then atleast youl still have a nice complete boat to show him ,just before you break his neck
Is it something special you need ?
as for pewople having new hatches made to replace sunken ones, why not get them
made hollow and filled with foam so they will float !!!!!!
surely it would make sense to have floating hatches for all boats realy, i know the cost might be a bit more, but well
worth it, especially if you have a real fancy paintjob on it .
