RE: When sailing in warm places...
I wear an Ultimate Hat, made in Florida. You can find them on the web. Heavy cotton, pretty stiff brim, chin strap, they float and they last almost forever. Lifetime warrantee, and I actually replaced one just recently (free hat after sending in the old one).
I put on the sun screen (SPF 40) on all exposed skin before leaving home, which seems to work best.
All my cancers have been basel or squamous cell and have been small, plus they generally don't spread. The bad stuff is melanoma and they take A LOT of tissue with any removal. They can kill you.
If you get them when they are small, there is no time out of the water after removal, but I go in at least 3 times a year for check ups.
I see all these young guys with no shirts and no sun screen - one day they will wish they hadn't been so dumb.
