Without stepping on too many toes....
Doing the New Jersey Intracoastal in a 34 Mainship is relatively easy.
Most of the inlets outside of storms aren't as bad as advertised, and the shallows are easily navigated with a less than 4 foot draft as long as you don't travel on dead low tides.
Sure, run outside to make time...but if caught in bad weather.....many, many loopers and snowbirders travel this way every year.
When in doubt, go slow and every port you stop in, buy the Sea Tow or BoatUS guy a beer and pick their brains.
