We size them very carefully to go in hard when they’re dry, and it doesn’t take a lot of moisture to swell them up. Some people have done double-wedged trunnels, where a wedge is put on the inside end of the trunnel, and then this wedge is driven home when the trunnel bottoms out. That’s a lot of work and we don’t really see the gain. This is quite apparent when we remove original planks. Even though the planks are long and heavy, they stay attached to the boat until we cut the very last trunnel holding them in place. After 170 years, that’s pretty impressive.

Is it wedged on the inside? I see that the trunnel is tight on the outside. What keeps it tight on the inside so that the plank stays firmly attached to the frame or first layer of planking? Thx for great pictures!
