I have been through more than a hundred forum entries in the Skerry and I have not found a mishap like mine. My mast step assembly broke under an 11-12 kt side wind coming from port. The mast had its normal bent. I did not see the breaking process since I was focused on the sail and mast, purely enjoying the ride with my 15 years old son. My analysis is that under the lever effort, the side of the mast step box began gradually to pull the screws through the floor and tear the first layer of the oecume plywood upon which the box was firmly epoxy bonded see photos). Then the port side of the box broke in two pieces and the mast took a 45 degree angle. I quickly pulled the mast out to prevent complete break, pulled everything back in the boat and rowed two miles back to the shores of lake Saint-Louis near Montréal. Luckily, I had filed the underbody over the screw heads, so no water came in. But I was much surprised by that failure. Maybe I had sunk the screws a bit too much? I plan to build a different mast step using a 6”/6” solid piece of ¼ wood screwed and glued to the bottom, with an 1 inch high U-shaped piece of solid wood glued over it. Is there any reason why the normal mast step is 3 inches high?
