Chris on the dock was the best and more than helpful. Restaurant soo much better than last time which was before Covid. The walking map very helpful in understanding where the permitted places were to walk. Street names would be helpful on the map. The lady at the inn fixing our bagel breakfast could not have been nicer. She made our morning. Good job to all.

Amazing, secluded little spot. Food and drinks at Diamonds Edge restaurant are phenomenal. The dock master Chris is friendly, helpful and accommodating. The inn is beautiful and we’ll probably stay a night or two next year to break up a long boat vacation. My only complaint is there is limited hot water if someone is in both the men’s and women’s showers. You might end up running out so best to put some time between showers.

Thank you for your 5 star review of Diamond's Edge Marina.

As always, this is one of the most pleasant marinas to pull into. They're always waiting for you to arrive and ready to help you dock. And it's such a beautiful location with great food and fun beaches!

Marina Response:

Thank you for a wonderful review of our Marina.

Great small marina with two good restaurants a short walk away. Note-No WIFI or cell service. Chris Johnson, the dock manager, is the best!!

This location is absolutely beautiful. Small protected cove, very close to Portland. The amenities are limited...no wifi, spotty cell service, bathrooms are quite a long walk. The residents of the island do not want marina guests to walk around. You are required to request a golf cart ride up to the Inn to use the pool. Chris is a very pleasant and customer service oriented manager. He does a great job! Also, skip the Diamond's Edge restaurant and eat at Crown Jewel instead where the food outstanding!

Diamond’s Edge Marina was amazing! Dockwa calculating the wrong dockage fee was our only issue.

Marina Response:

Thank you so much for your kind review. The Dockwa pricing issues, that under charged, have been corrected. We look forward to seeing you again soon.

The dock manager was very helpful and friendly. They are a little short handed, but everything seemed to get done and I got all the help I needed.

Marina Response:

Thank you Chris. It is always a pleasure having you visit. We will look forward to more island stories on your next trip.

The dock master was rude and offensive. He asked us to tip the dock hand which we already had done. He then came to our table to confirmation our reservation which we did online. He again asked us to tip the dock hand. When we returned to our boat, he asked us again about tipping the dock hand. He was pleasant enough, but was extremely rude and intrusive by constantly chasing us down for the fee for stopping at the dock and tipping the dock hand. Unfortunately, I will not return there because of him. I guess the $250 lunch isn’t good enough.

Marina Response:

We sincerely apologize for any misunderstand during your recent visit. Recalling the conversation we feel it was misconstrued that we were seeking a gratuity, but rather the options available on Dockwa. We are committed to providing excellent service to all our guests, and we will review our communication guidelines with all staff members.
