I cannot speak more highly of this Marina. The amenities were top-notch (other than wi-fi) but more importantly the people were extraordinary from the lady who runs the cafe to the management, technicians, dock master and dock hands. Had some unexpected electronic and other issues and these were taken care of in the most professional manner. Most marinas could care less about transients but this Marina treated me as if I was a long term customer. If they were not so distant from my home base they would be my base of choice. Cannot wait to return.

Simply the best boatyard and marina on the east coast. A beautiful, protected location with very qualified people. Everyone is cheerful, helpful, and always pushing to exceed expectations. We give great island an A+

This is a fantastic harbor that is beautiful and very well-protected. Safe Harbor Great Island's facilities and people are also top-notch and have made our multiple stays here very enjoyable and comfortable. This past winter we also chose Great Island for some major maintenance and upgrades on our sailboat and were thrilled with their capabilities, timeliness, and results. It was a complete pleasure to work with the team and they exceeded our expectations on every dimension. We're already looking forward to our next visit to Great Island!
Marina Response:
Thank you for taking time to share your experience. Our team certainly enjoyed the opportunity to collaborate with you to achieve your goals. It was a pleasure working on such a lovely boat, and with such lovely people! We look forward to your next visit.

Top notch service. Christine, Dillon, and Annika went above and beyond my expectations. Located in a beautiful cove.

Great Island came recommended to us by our broker, who had previously been at the yard for remodeling the office cabin into a guest cabin. The carpentry work performed was excellent, and I was informed that the yard was the best in the area. We came in for refrigeration work, and it was accomplished on time and to high standards. I have experienced boatyards and marinas on the Eastcoast, from top to bottom, and do not hesitate to recommend Safe Harbor Great Island for their professional work and customer care. Plan early so as not to miss a lovely spot and great people.
Marina Response:
Thank you for sharing your Great Island experience. We appreciate that a yacht broker recommendation lead you to us, and hope that your review will do the same for others. Referrals have a way of connecting us to those who truly value the kind of service and experience we offer. We enjoyed meeting you and caring for your Fleming 55. Please visit us again when you return to Maine!

The staff at SHGI is simply top shelf. They recently completed the second refit of my 58' sailboat over the last two years. I've dealt with a number of boatyards over the past 15 years from the Chesapeake to Maine. SHGI's staff possesses an unparalleled level of skills and craftsmanship across many disciplines from rigging, propulsion, refrigeration, systems and electronics to paint, varnish, fiberglass, cabinetry and even teak decking. And it's all delivered with an amazing level of customer service from the time you first hail them on VHF to when you call for advise from a thousand miles away.

Well protected mooring area with easy to pick up pendant. Mooring field is not close to the marina so could not pick up any Wifi service. Nothing really within walking distance of the facility that we could find. There's a busy two lane road with no sidewalk. However, the beauty of area made it worth the stop. Spent time exploring the coast and islands in our dinghy. It's just a nice, quiet place to hang out.

by riddei63 on Sep 06, 2020
Such a beautiful spot tucked in a very protected spot in Eastern Harpswell. A great launching spot with easy access to explore the Mid-Coast Maine. Dock attendants are helpful, as well as cheerful. There is a relaxed low key vibe which is in contrast to other Marina's further down the peninsula. Restrooms as well as all facilities are clean and updated. Communication and instructions from the marina was clear and understandable. I will definitely stay again in the future.

Great staff, clean yard.
Marina Response:
So glad you enjoyed your stay! We hope to see you again.

by abain0265 on Aug 04, 2020
The staff here were amazing. Squeezed us in so we had a slip that night. Kristen was very helpful to and super knowledgeable. All the dock hands knew exactly what they were doing. Provisions was so good with nice sandwiches and take away wine. The marina is very protected in the river and full of beautiful scenery. Laundry was in good shape.

by amills on Jul 18, 2020
Excellent service and friendly staff. Be sure to check out Craft Kitchen for lunch or pick up a prepped meal for dinner on the boat. They could have one of the best brisket sandwiches I have ever had and my kids loved their homemade ice cream sandwiches.
Marina Response:
Thank you for letting other boaters know about Craft Kitchen & Provisions. We enjoyed getting to know you and your family. There's nothing better than seeing kids come ashore for ice cream! We hope to see you again soon.

by trust2deal on Jul 13, 2020
Great staff - awesome location- great amenities- will definitely go back
Marina Response:
Wonderful! We look forward to your next visit.

by kmaine66 on Jul 13, 2020
Beautiful Oars Harbor!
Marina Response:
Thank you! Orrs Cove and Quahog Bay are among Maine's best kept secrets. So glad you visited us! Hope you'll come again.

Great Island Boat Yard (aka GIBY) is quite literally one of my favorite places in the world! They have become a seriously fantastic landmark for quality boat work... Some of the finest boats come to GIBY for reliable projects! Most recently: I've worked with Graham Wright as a service manager to get a Sabre sailboat back up to snuff and cruising again. He's been super responsive and helpful. In the offseason, you'd be lucky to have your boat stored and serviced inside one of their gorgeous indoor warehouses. In the summertime, GIBY is a wash with gorgeous boats!
Marina Response:
Charlotte, thank you for recognizing GIBY - and Graham, for his hard work and dedication. We're lucky to have him as one of our Service Managers. We look forward to working with you again - when you assist your next client with buying or selling a boat.

I’ve sailed to 21 countries, 50,000+nm, and I count my blessings that Great Island Boat Yard is my home port and home base. Extraordinary craftsmanship and work ethic; work done cost effectively; big enough to do sophisticated projects, yet friendly totally hands-on family-owned and small enough to be comfortable and informal - everyone on a first-name basis. Mantra to always go the extra steps to exceed customer expectations. Excellent proactive communication and responsiveness. Immaculate facilities; gorgeous, protected cove that makes hanging out at dock or mooring as much fun as sailing coastal Maine or across an ocean. Haven’t found another yard that comes close. - John Reid s/v Ramble Too (written from Guadeloupe)
Marina Response:
Wow! We're humbled to be ranked across such a broad spectrum...and very glad to still be your home port. Bon voyage! We look forward to your return in 2020.

When searching for a place to keep a Cape Dory 36 somewhere in the Casco Bay area I found GIBY on Google Earth, drove up to look at the yard on a Sunday in January and immediately decided it looked like a great spot. Been there 5 years now and can’t say enough good things about the place. The yard and facilities are well kept, staff is very professional/friendly/helpful, the location is well protected and the on site cafe is super convenient. Service at the yard is unparalleled in terms of timeliness and quality. My family and I look forward to being back at GIBY each summer.
Marina Response:
Thank you, Scott! We're glad you found us and enjoy having your boat as part of the summer fleet. It's great that you're taking full advantage of Craft Kitchen & Provisions, onsite. We think Pamela's food is one of Quahog Bay's best kept secrets. It's time to get the word out!

by davidntaft on Nov 18, 2019
We have stored our sailboat at BIBY for many years. This yard is unequalled for its professionalism with a specific manager assigned to each boat, knowledgeable and accommodating staff, and great relationships with subcontractors (extensive engine work, sailmakers, dodger work, etc.). Our boat has been carefully prepared and has been on time each year. Just as an example, we have had many people admire the terrific job GIBY has done each year on our extensive brightwork. I can highly recommend GIBY to any boat owner who wants an outstanding yard to care for their boat.
Marina Response:
Thank you for your kind words, David. It is our pleasure to care for your boat each winter. We consider the relationships that we develop with our customers a job perk!

by pl1964 on Nov 16, 2019
Sailing from Scotland to New Zealand and did small refit at GIBY Sept 19. A very professional and capable team, owner hands on and has recruited a fabulous team. Peaceful location and GIBY team could not have been more helpful. Offered well thought out alternative solutions to suite my boat and ocean sailing requirements and met tight time scheduled. Could not speak highly enough of this team, it was a pleasure to be one of their customers.
Marina Response:
Pauline! It's so good to hear from you. We think of you often as you make your way toward the Pacific. We look forward to hearing your sea stories and to receiving pictures of your boat in faraway and exotic locations. It was our pleasure assisting you in preparing your boat for this leg of your journey. Please keep in touch!

by risingsun on Nov 14, 2019
We've spent several nights on GIBY's moorings- always a pleasure. Great friendly staff, exceptionally clean restrooms & showers and well-protected moorings with all of Quahog Bay to explore. Friday night gathering on the deck was great, and breakfast at the cafe was a very nice break from cooking onboard. We'll be back!
Marina Response:
We look forward to your next visit, Al and Nita. We hope you'll continue to take advantage our our summer Music on the Deck series. And please tell your friends about Craft Kitchen & Provisions. Pamela's food is one of Quahog Bay's best kept secrets!

by dvonloes on Nov 13, 2019
Best marina and full service boat yard I’ve ever worked with. Highly competent staff who go the extra mile to serve you whether it be repair work or dock service. I’d go out of my way to have this boat yard do work for me.
Marina Response:
Dave, we're so glad that our paths crossed this summer. We enjoyed working with you and bumping into you again at the NIBS! We hope you'll visit GIBY again, the next time you're in Maine.

by woodinwj on Nov 13, 2019
Great Island Boat Yard is a terrific yard! We are very pleased with their service, their work, and especially their can-do attitude. Kristin and Graham communicate well and do everything to accommodate our requests. We are very happy to have our boat there.
Marina Response:
Thank you for the encouragment, Tony. We're glad to have the opportunity to care for your boat.

by captjackswan on Nov 13, 2019
GIBY is a great marina at the East end of Casio Bay. The staff is friendly and knowledgeable. Their ability for maintenance and service is excellent. I stopped by one day and was so impressed with their ability, I had them perform a number of repairs, including a stove replacement, stereo upgrade, and satellite tv installation. All done for a reasonable fee and with fine quality installation. One of my favorite stops in Maine.
Marina Response:
Thanks, Captain Jack! It's nice to hear from you. We hope to see you again, on your next visit to Maine.

by kstinson on Nov 09, 2019
Great facilities with always a helpful hand on the docks! CLEAN new building They have a great parts department for DIY and the best folks ever for fixing ANYTHING.
Marina Response:
Thanks for the kind words. We hope you're enjoying your winter sailing and the opportunity to explore Puerto Rico!

by willblake on Feb 02, 2019
Great workmanship, friendly staff, a tasty if small cafe, and a well protected harbor. I have docked at GIBY for over 10 years and have never been disappointed in their work. I head south in the winter and they are always ready to help with questions along the way and amazingly can almost always solve the problem without an eyes on.
Marina Response:
Thank you, Will! It's our pleasure to care for you and your Lyman-Morse 42. We look forward to your return north each season - and the sunshine you always bring. The cafe, Craft Kitchen & Provsions, will be open again in late May. See your for lunch!

by bonnijean on Jan 25, 2019
Excellent facility...very well managed with a friendly staff. We had complicated transmission work done and we were delighted with our technician and the results. Top notch!
Marina Response:
Thank you! Our technicians always appreciate a good challenge. Glad we could help. We hope to see you back in Maine soon!

by richfef on Jan 25, 2019
5 star marina and boat yard for sure. I stayed at GIBY in September. They put me on a mooring close by the docks. Very secure and protected. They have marine supplies and service on site and excellent amenities as well.

by misaak on Aug 12, 2018
No one there when we arrived at 8 PM Saturday evening and no combination to the bathroom
Marina Response:
Maria. We want to apologize for your negative experience at GIBY. We understand that you arrived at 8pm, after hours, and did not have the combo to the heads. We should have reached out to you when it was apparent that you would not be in before closing, as planned. Please know that the Dockwa chat option is always available, even after hours. Your experience is a reminder to our staff, that we, too, can reach out electronically. We enjoy a 5-Star rating and are sorry that we missed an opportunity to deliver the experience you should have had. Our staff had hoped to greet you this morning, but you were already underway. We hope there will be another opportunity for us to get it right.

by johnd0623 on Aug 11, 2018
Entire staff that we dealt with were friendly, welcoming and helpful. Were a big help with a repair we needed done too. Special shout out to Kristin and Graham for the hospitality and assistance!

by marinekat on Dec 05, 2017
My husband and I over the years have been in many boatyards and marinas on the eastern seaboard and in the Caribbean for repairs, overnight stops and even storing over the winter. It's safe to say we are a fairly decent judge of what makes a good boatyard. When we found GIBY, who have now looked after our boat for over 4 years we were blown away by the service, talent of team, the customer-service driven atmosphere and love of boats! They are outstanding at what they do and I personally think one would be hard pressed to find a better yard on the east coast. My husband jokes (maybe not a joke) that if they ever sold their yard that he would leave boating forever.
Marina Response:
Thanks for your kind words, "MarineKat".

by rhrubin on Aug 22, 2017
Very friendly and helpful crew. Beautiful protected cove. Clean, hot, spacious shower rooms. The whole boatyard is oederly and well run.

by kenherd on Aug 11, 2017
Kristin - thanks again for the "platinum" service at Great Island Boat Yard on Wednesday... We'll be back soon! I'll keep an eye out for your email as a follow up, as we discussed... Best regards, Ken
