Re: Heading to the Keys!
C.Dad is right, skip dry tortugas.
its actually harder than going to bimini. -in Bimini you can buy fuel, ice /water. there is zip in Dry tortugas.
Ft Myers is a good resupply point, as is Marco island. from marco, not much till marathon.
you're going to need to go around cape romano, so everglades city might be back tracking... but new turkey key would be a good stop, or shark river. once you leave shark river, no stopping places till long key/marathon.
and you want to sail there. too many lobster / crab bouys (til the end of march) to motor... (IMHO).
you're going to need some bug screens at shark river... or at least a head net. worst at sunset / sunrise. put them up before the wind dies! (or else).
mosquitoes are nothing compared to no seeums (sand fleas). skin so soft will coat your skin so the sand fleas dont bite.. (or oil based sunscreen).
