A good fit in carvel planking requires that one plank touches another. Ideally, light will not pass through the seam. This almost always requires some sideways pressure on the plank being hung. Sometimes, a good jolt from the base of your palm might be enough to bring the planks together, or you might need to rig some wedges or clamps. A clamping system should be easy to apply and it should exert adequate pressure without damaging the edge of the plank. It should not be restricted by molds, ribbands, or adjacent frames; and it shouldn't obstruct the placing of the plank fastenings. The chain clamp presented here meets all of these requirements—and a pair of these clamps will be even more useful.
