I own a 2001 410 and have done the trip several times now. The
water levels are down now in South Carolina so you won't have any problem with any of the bridges on the way down. The only bridge you won't make is the Julia Tuttle bridge in
Florida. You have to go outside somewhere before that bridge. We go out at
Fort Lauderdale and
head to
Government Cut in
Miami.
The 410 has a 62' airdraft and with a three foot
antenna on my
mast, I haven't touched a bridge yet. You will be fine.
The only guide I use is
Skipper Bob's Guide to
Anchorages on the ICW. It has served us well, but there are other good guides out there. I'm sure others will chime in with their favorite. By the way, which 410 did you buy?
