The worst possible outcome is that the CBP agent doing the review requests you and your crew appear in person, with a possible significant delay. You can anchor in the Cruz Bay Creek in 6-feet for 3 hours. You can tie up your dinghy. at the dinghy dock near the NPS Visitors Center in the creek (concrete, not the dock) or the dinghy docks on either side of the ferry wharf (possible port fee). Note your ROAM arrival number. If you're detail oriented, you can also download, fill out the arrival documents, and print.
