Is the Woods Hole to Martha's Vineyard crossing rough?
Rarely. Woods Hole to Martha's Vineyard is the gentler of the Cape's island crossings: about 45 minutes on Steamship Authority car ferries, roughly hourly, across Vineyard Sound with the Elizabeth Islands close to windward. A hard south-westerly against the tide can chop the middle; most days it is a calm, short, scenic run.

Why the Woods Hole to Martha's Vineyard crossing gets rough
Vineyard Sound is narrower and better flanked than Nantucket Sound, so wind has less room to build waves before they reach the route. The strong tidal streams through the sound add chop when wind opposes them, which is the crossing's one honest trick. The car ferries are big, steady and utterly practised at it.
When it's worst, month by month
Summer south-westerly afternoons supply mild chop; fall and winter storms the occasional genuinely lively crossing. The service's frequency makes waiting out an ugly hour easy.

For the full toolkit see the seasickness guide, or what to do once it has already started. Choosing between a fast catamaran and a conventional ship elsewhere too? The physics is the same everywhere: see the catamaran guide. If the rocking follows you ashore afterwards, that is land sickness, which is normal, and it passes.
Frequently asked questions
Is the Martha's Vineyard ferry rough?
Usually not: the 45 minute Woods Hole crossing runs in the more sheltered of the Cape's sounds on large car ferries. Strong south-westerlies against the tide can chop the middle briefly, and winter storms have their days, but the baseline is calm.
How long is Woods Hole to Martha's Vineyard?
About 45 minutes with the Steamship Authority, sailing roughly hourly to Vineyard Haven (and seasonally Oak Bluffs), which makes it one of New England's most frequent island links.
Is this crossing calmer than the Nantucket one?
Meaningfully: it is a third the open-water time, better sheltered by the Elizabeth Islands, and served by conventional ferries rather than fast catamarans. Motion-sensitive travellers planning both islands usually find the Vineyard leg the easy one.
Do I need anything for seasickness on this route?
Almost never; it is short and sheltered. The very prone can sit centrally on breezy afternoons, or ask a pharmacist for general travel advice, noting the crossing lasts about 45 minutes.
