Lower Hull Planks

Mark has spent the last few weeks in the mud under Shamrock renewing the caulking of any suspect bottom hull plank seams. He has also power washed and scraped these planks ready for a coat of bitumen paint, none of them easy jobs.

Shamrock has been out of the water since October 2017 and needs to be back in the water to prevent her ‘below the waterline’ elm hull planks completely drying out. As her false keel and keelson still need to be replaced, the centre section, approximately 4 ft. (1.2 m) of deck planks, are not going to be replaced until after this work is completed. The newly laid deck planks are being cleaned of 'black butter' (bituminous mastic), sanded and the inboard edges braced ready for caulking. Once caulked the centre gap will have a temporary watertight cover fitted. Shamrock will then be floated off her cradle and returned to her dock. While Shamrock is soaking, the cradle will be modified ready for her to be hauled out later in the year. Work can then be started to complete the second phase of her current conservation work.

To make Shamrock's hull more pleasing to the eye, Shaune, the perfectionist, has started hardening the seams of the upper hull planks using a hot iron.
