Chainplates
Many owners have replaced the 6mm shroud U bolts with 8mm dia versions. Marinestore sell an even better A-bolt, which has a flange welded across the legs making it very strong – the web address for this part is http://marinestore.co.uk/page/mrst/PROD/u-bolts/PBBW-408518/. The flange also helps to ensure a good watertight seal as there is a large area on which to apply a bed of Sikkaflex.
If you have a Corribee which has been built as a kit boat you may be less than happy with the way the bolts have been fitted. It is fairly easy to strengthen this part of the structure using stainless steel backing plates to spread the load over a wider area. The photo below shows the A bolts fitted through holes in the full length plate. The plate itself is bedded onto the underside of the deck with a generous layer of thickened epoxy resin (to ensure the load is spread evenly). Reinforcing straps are bonded to the hull side – these have been drilled pepper-pot fashion so the epoxy has a good mechanical bond.
The strap has to pass through the bulkhead (one of the A-bolts actually straddles the bulkhead). The straps themselves will be covered with lining material eventually (probably polypropylene carpet material, which many owners have fitted in preference to the original foam-backed vinyl). Some finishing work is needed – the original ply backing pads had been glassed in so the whole area needs a good rub down followed by a coat of thin epoxy resin to smooth it out. The A-bolts also need trimming to length.
