Customer Comments:

We respect your boat as much as you do ! Established 1997 and we care.

“I have a Sealine S28 at Conwy Marina near Deganwy and unfortunately we had a recent issue with engine failing to start. MES came out to view the boat and within 2 hours had it up and running again which was a huge relief as I was expecting a huge boat repair bill. The weekend continued and we now have MES service the boat every year ensuring its in fine working order.”
