I have a "Wayler YPSI" made some bygone year before i was born, a time when the UJ was just a glint in the eye of young sailor. Instead of a mast track, it has two bizarre cylindrical sink holes, where (I assume) some antique style hinge is suppose to connect the board to the mast.

So, i'm looking for a seasoned and knowledgeable sea dog who'd be familiar with this type of board, or if they've seen anything like it. Or do i need to break out my custom-job-hat and start hacking into the mast box?

Please help, i don't want to see a good board gone to waste.

Thanks for your time, David
