Sunfish mast question

My other option is to rent a scuba tank and go looking.

Maybe send your message along to the local diving schools like www.divewinnipesaukee.com, www.fathomdivers.com, and www.productiontraileranddock.com and could be that one will retrieve it as part of a dive class training activity. That actually worked for me once with a trolling motor and battery lost off my 14' sailboat when I flipped it. Two weeks later or so, I came home on a Saturday and found the trolling motor and battery sitting on my dock, and Winni Diver had left a note that it was in 48' depth, and way off from where I said it was but they found it anyway, and all for free!

Here are the correct dimensions:

2.25" OD
0.065" wall thickness (so I think 16 gauge?)
122.25" length, plus or minus 1/4". This is the only mast dimension in the Sunfish class rules. If you don't care about ever racing with that mast, then roughly 122.5", but no less than 122".

Use 6063 anodized aluminum. Definitely make sure it's anodized. Ask me how I learned that.
