I wouldn't bet on getting away with breaking the law even on
charter. Chartering on the French side is your best bet as was it was said above, all the "good" places are on that side. Everything on the Dutch side can be accessed by
dinghy or bus or car. With only one week taking side trips to
Anguilla or even St Barths, etc. is not really feasible if you want to "stop and smell the roses" kind of thing (not to mention sniffing around Orient Beach). If you want a week of "sailing experiences" then for sure the trips to St. Barths,
Saba, St Kitts/Statia/Nevis and back will give you some serious sailing fun.
