is completely unique - great place to visit. i don't know about anchoring
there it is very rolly. There are 4 balls close to the harbor where customs/immigration and the road to the towns at the top of the hill are located. the rest of the public balls are around the side of the island - about 1 mile away - and a very wet dinghy
ride. When i was there we didn't see anybody anchored - all on balls (free) but having a rough night.
I have keep my boat in Simpson Bay for the last 7 months, but leave St Maarten every 3 or 4 weeks - so i have had no problems. in addition to the bridge fee i pay about $40 a week to be in the lagoon on top of any marina fees
. I get a lot of growth on my prop and thru- hulls etc - need bottom cleaned every 3 to 4weeks, and there is NO way i would swim in the lagoon.
