Boat building planking strip

This is why clamping strips are installed on the forms; so that stubborn planks can be pulled into place. Instead it bunches up in the most offensive manner and on many hulls has to be cut down periodically so that a fresh start can be made. Once up the right way the inside of the hull is cleaned up and may be sheathed. In larger hulls with internal framing the glass sheathing is often applied only on the outside. Ideally, planks are long enough to put on in one piece, ideally, but it usually doesn't happen that way. Gaps are filled with thickened epoxy, faired, and the hull covered with fibreglass and epoxy, then usually painted. That assumes the only passage for water is through the laminate, but every time a through hull is installed or a fitting is bolted through the hull there is the potential for water to enter the core.

To me it seems the height of optimism to think the enormous stresses in an edge glued hull can be controlled by a skin of glass glued to one face. Two methods are commonly used to fit flat strips around a curved form and not end up with gaps. This frame will support the strips as the shape of the boat is gradually built up. Any of these methods work, but some may have advantages on specific designs.
