Rear Plank Attachment Assembly Reinforcements
I decided to use 1" x 2" x 21" hardwood to reinforce the area that holds the rope assembly that holds the rear plank. I used my dremel to route out the foam to receive the wood.





The lag bolts that hold the rope assembly are 2 1/2" long so this depth should be adequate.



I left a little hanging out so I can sand them down to the shape of the foam. You can also see the hardwood for the mast base, rear block and sheaves for the sheet.



The hardwood extends back to help distribute the load from the plank and also absorb the punishment from the blocks that center the plank on the boat.
