Post subject:  wood gunnels on Rx canoe

I am replacing the gunnels on one of my Rx canoe. I was wondering if I should make the holes going through the haul a bit bigger to allow for the expansion when the temperature will drop. Any recommendations

Yes, good idea to make the 3 or 4 holes at each end oversize to allow for contraction. If not you should back out the screws for those holes over the winter.

I've had cold cracks two times. Some people say loosen the first 3 or 4 screws in each end. Some say remove the screws and lift the gunnels out at the ends.

One was on a dagger. They somehow machined the decks and inner-gunwales flush with the hull the screw holes were slotted so it didn't crack there, it cracked at the top of the stem on one end where the gunwales were trying to push out the end of the hull. In response to that I replaced the deck with a plate on top and cut the inner-gunwales an inch short so any expansion should be all set.

The other was a Mad River Eclipse it cracked along the screw holes in two places.
