A few thoughts…
Day 2 … probably need a Boaty Ball at Coopers depending on time of year
Why dinghy to Saba …easy to move boat , visit saba rock and/or Bitter end.
Dinghy and snorkel the cannons ?
On Anegada… Flash of beauty is the best snorkel spot. Also great for lunch!!
Day 5 Indigo house … get reservations
Day 6 .. Boaty ball at great harbor.
Another approach is to go to B line on Day 5 … go early the next day and anchor at Soggy Dollar if you are comfortable with that. Night at CGB.
Skip Sopers hole
St John is excellent … but unless you have a couple of days not worth the check out(BVI) check in (USVI) check in BVI. Way easier than before but still takes time.
Cheers
