Very picturesque spot

Mooring is sheltered and not far from the dock. On shore within 3 blocks are several restaurants, a hardware store and a small grocery with liquor. Pleasant community with many unique victorian style homes.

Onset is a delightfully small town with friendly people, ice cream stores and Victorian homes. Quiet mooring surrounded by pretty beaches and shallow water. Canal cruise boat departure point. A very relaxing stay.

There is no designated slip-holder parking at this marina and no where to leave a trailer. This posed a huge inconvenience for me. There are limited public metered parking spaces on the pier and they were full at 10:30 a.m. I had to park two blocks away in a two hour spot and return every two hours to feed the meter. I like to bring friends on the boat, and they also had trouble parking. I have stayed in many other marinas, and have never had this problem. Besides that, this is a pretty harbor. Good-sized slips, clean bathrooms, some nice eateries nearby and good beaches.
Marina Response:
Hello and we apologize that we didn’t meet your needs. This area is not a marina and the entire center of town where our pier is located is open to the general public. There is a marina and yacht club in the same harbor that may be better suited to your needs for future stays.

The approach is well-marked and mooring field is very protected. The current can be very strong at the mouth of the dredged inlet, so you have to be cautious. The harbormaster was not working the day we arrived and we were unable to contact anyone on the requested VHF channel upon our arrival. He told us the previous day what our mooring ball # would be. However, when we got there, someone else was on that ball and we were not quite sure what to do, so we just picked up different ball - hoping no one else was planning to come to that one. It got sorted out the next day, which was fine. The harbormaster was very helpful with the launch service and letting us know about the amenities at the dock (pump out boat, pump out station, water, fuel, restrooms, etc....). We stayed 2 nights and would definitely come back - a really pretty place.

Wonderful place to stay ! Always a pleasure 😎

Onset is the Jewel of Wareham. A hidden gem and a beautiful place. Well protected from the busy Hog Island channel. Moorings are my favorite but there are 5 slips with power, water, and pump-out on new docks. There is a market, a hardware store, Quahog Republic restaurant, and Marc Anthony's pizza all next to the pier. Public bathrooms, no showers, efficient launch service, dinghy dock. I love this place!

Great little town and pretty harbor. Super shallow in many areas but plenty of water where needed.

by rdgresham on Jul 12, 2020
Beautiful harbor with great town owned slips and moorings. Water on the dock.

Great moorings on the back side of wickets island

Great place to stay, great beach. Good bus service for shopping

The best thing about staying in Onset is the launch service. The drivers are unfailingly polite, helpful and responsive. We made several trips in for laundry and grocery shopping and never had to wait long. Our hats off to the whole harbormaster team, especially Antonio who dealt with us on both days. The moorings are a great deal. They are secure and stable in protected waters. The docks have gotten better this year, too. They are new and can handle about 6 boats up to 35 ft and one additional on up to 50 ft. They all have power and water. This is a huge improvement over the past. There are several restaurants close to the pier and two ice cream places nearby. The laundromat is less than 4 blocks a way. There’s a small market and a hardware store right in the village as well. Stop & Shop can be reached by a $10 Uber ride. Onset makes a great stopping point for boats transiting the Cape Cod Canal,

Happy I liked it will be back

We’ve spent lots of time here over the last 5 years. Onset Harbormaster has moorings close to lots of bars and restaurants, provides a launch service, dinghy dock and pumpout boat. You can actually swim off the back of your boat because the HM enforces a no wake zone in the harbor.

Lovely setting amongst the beaches. Nice having the free launch service into town. Restrooms are shared by beachgoers, they could use some updates. Town has a few restaurants and a mini grocery/ liquor store. Overall a nice stay.

by mentalblock on Jul 14, 2019
New docks, good water and electric service, pump out right at the dock. Short walk to village and beach. No showers but i knew that. Occasional noise from party fishing boat and canal cruise boat. A nice layover for our run from Watch Hill to Gloucester.

by mrossik on Jul 12, 2019
Very nice stay. We used the mooring to watch the Onset fireworks. Everything worked out great.

by danarc29 on Jun 26, 2019
Beautiful and well protected harbor . At the entrance to the cape cod canal so watch the tides carefully. Its a really wicked current. Great little town, with good restaurants and places to hang out. Welcoming !

by jereyns69 on Jun 23, 2019
The launch service runs until 10:30 pm in the weekend and the staff are friendly and knowledgeable. Picturesque harbor with lots of sand to enjoy

by bobbratt on Sep 30, 2018
No tender service after Sept 1st and our favorite clam shack was closed for the season as well. It was an easy in and out.
Marina Response:
Thank you for the review! We unfortunately had a couple mechanical issues beyond our control that led to some down time of the launch service. We do normally run until October 1... Hope to see you back!

by propstrike on Aug 22, 2018
The staff was awesome! They were extremely responsive with their shuttle service, always very courteous and quite helpful. The town of Onset is great, with lots of little shops and restaurants.
Marina Response:
Thank you very much, glad you enjoyed yourself! Hope to see you next summer!!

by jtdunn21n on Jul 08, 2018
Very accommodating harbormaster crew with a complimentary shuttle. Harbor very calm and enjoyable most anything you could need is within walking distance.

Great place and people.

by unclegkw on Aug 06, 2017
1. Reasonable mooring rate. 2. Free launch service 3. Friendly launch crew 4. Showers would be an appreciated amenity. 5. Onset Village is low key and not self-important.

by reeltime on Jul 03, 2017
I had my boat on a mooring for two nights in Onset. They provided free launch service and were very friendly and helpful. We had a great weekend there, thank you.

by silverheels on Jun 29, 2017
The moorings are great and the harbor nicely protected. My only comment is that it is a bit confusing for a newcomer to the harbor figuring out where the moorings are. The moorings are obscured by Wickets Island when coming in the harbor and one sees many moorings at the private marinas to the east. It would be helpful if the info on the confirmation included an instruction to proceed past Wickets Island keeping it to starboard and enter the town mooring field on the northwest side of the island.
