At this stage we also checked the fit of the daggerboard. It slid nicely through the slot in the hull. Kevin had glued the end spacers to the one side of the daggerboard casing but the second side was still loose. When we checked the fit, the board wouldn't go through. Checking the sides for straightness showed that they bowed inwards a few millimeters, enough to jam the board. That gave warning that care had to be taken when gluing it all together to ensure that the sides remained straight throughout the height of the casing.

Kevin called on me to assist with fitting the rub-rails. The laminations are fitted in single lengths (scarphed from short pieces), so are awkward for one person to handle in a confined space. Getting them correctly positioned on the wet glue while also working with clamps calls for some ingenuity if working by yourself. It is simpler to call in a pair of extra hands.
This job calls for lots and lots of clamps. We did both sides in one evening, which needed all of Kevin's clamps as well as all of mine. If you are brave and short of time then you might want to laminate all layers at the same time. This is risky because it needs slow-setting glue that won't set before you are able to wet-out all strips, get them into place, manipulate three or fours slippery lengths into proper alignment and get all the clamps in place and correctly tensioned.
We chose instead to do one layer at a time. Rather than four layers of equal thickness, Kevin prepared inner and outer layers of poplar and a middle layer of cedar of double-thickness. This gives a nice stiff gunwale with a tougher outer surface than if all layers were cedar. It is also very pretty.

When gluing all laminations after the first one, it is best to get the bottom completely flush and let the top look after itself. The reason is that it is very easy to clean up and neatly finish the top but much more difficult to do the same to the bottom of the rail because of the adjacent plywood.
