My son and his wife are joining us 3 days after we set sail. They are flying into EIS and landing at 3:15pm on Monday, July 2nd. Is it possible now to catch a mooring ball at Trellis, dinghy to dock, and pick them up? Then we are planning on going to White Bay on Guana for that night (first time at this anchorage).
If not possible, we would love suggestions on how best to pick them up.

Definitely possible.

I asked the same thing. See my Trellis Bay Questions thread on page 3. I plan to grab a ball in Trellis, dinghy over to the dock, store or beach, not sure where the best spot to land and then pick up one crew member. Her flight doesn't arrive until 4pm if it's all on time and I plan to go to Leverick. Everyone says I should be fine so I'm sure you will be too.

Thanks for responses, glad that dock is open to pick up. Only 10 days until we are in paradise!!

Thank you for sharing your thread, Schwendy. We are on a 44' Catamaran (not power Cat).

We've done this many times in the past. Works out great!
