Never mind your keel bolts what about your floors?
Built as an affordable cruiser/racer, some of the components in SCODs are fitted for cost, rather than durability. One major weak point is the galvanised steel/iron floors, which dissipate the weight of the keel into the boat. These are fastened with galvanised steel bolts, which pass very close to the copper nails that hold to the timber heels. Due to galvanic action between the two metals, alkali salts cause delignification of the mahogany and oak. In some vessels this means major work may need to be done, including replacing planks and frames.
A solution to this is to replace the steel floors and bolts with bronze, which lives happily in damp timber alongside copper nails.
We have the patterns, and can supply and fit a set of seven floors in NABII (Nickel Aluminium Bronze II) and silicon bronze fin head planking bolts. This will ensure your SCOD lasts for many years to come, without the fear of wondering what is really holding your keel on.
