Need mast base for OBrien windsurfer

Question
Need a mast base for old O'Brien (Coleman) Windsurfer to connect mast to board.
Round hole in board is 1 3/8 inches diameter.
Mast is 2 inches in diameter.

The winds are up and I'm itching to try out this old windsurfer!

Thanks!

Answer
Hey Skip,

I wish I could help you more but I have no resources for old O'Brien parts other than your local craigslist or ebay.

Because O'Brien windsurfers have not been sold in many years, it is very unlikely that any shop will have parts. Back when they were made, most manufacturers were 'brand' specific on how they made their mast bases and so very few brands were interchangeable. Around the late 80's most board makers went to the conventional mast track that is found on all boards today and all mast bases are designed to work with this conventional connection system.

Hope this will help.
Keep on sailing,
