Preparing and Fitting Hull Planks

A rough guide to fitting one of Shamrock's hull planks: 

Select a suitable sized plank and then, using a prepared template of thin plywood, mark out the plank and cut roughly to size.

Place in a plastic sleeve and steam until the plank is pliable using the steam provided by couple of wallpaper strippers.

Bend to shape by clamping to the hull, roughly in place, and allow to cool so that it takes the required shape, remove and cut to correct size.

Apply Stockholm tar to the inner face and sides of the plank and cover the areas of adjacent frames, which the plank will butt against, with ‘Bitumen Mastic trowel on' (black butter). This will form a waterproof seal between the plank and frames.

Clamp into place, drill out recessed nail holes in line with the frames and drive in the nails, ensuring they are well below the plank surface.

Plug the recessed holes with prepared wooden plugs and then cut them flush to the plank.

Fair plank to the thickness and shape required once the adjoining planks have been fitted.

Easy!
