I just found a shuttle boat that runs from the mainland at Crab Island Trading Company out to Crab Island. It's $10 per person for a "seat" on the boat that stays out there, so you have a boat to return to anytime. Starts at noon. Monday thru Friday only at this time. The boat stays out there and he shuttles back and forth every hour up to 430pm when the last shuttle back is. Were gonna give it a try while on vacation over there. Sounds like something good to do for a day, a raft up is always good. I've got his phone number if anyone needs it.
