We are fortunate to have a staff of highly skilled carpenters, mechanics, electricians, painters and fiberglass specialists in our shop. Their common goal is to build the best.

Our Philosophy

For over 30 years Coecles Harbor Marine has been dedicated to building some of the most unique and admired boats in the Northeast. Our meticulous attention to detail guides us through the building process resulting in boats that are of unparalleled quality and beauty.

Perhaps our determination for perfection in every aspect of our craft helps explain why the majority of the boats we’ve built are still in the hands of their original owners.

Our Materials

Each hull is built to last using vinylester resin and gelcoat, KEVLAR® fiberglass cloth vacuum bagged with a Corecell foam core. The hardware, system components and machinery we use have all been selected for quality and longevity. If it's a little more expensive so be it, we won't compromise. Only the finest teak is used when building a Shelter Island yacht, each piece being selected for grain and color. Then it is painstakingly hand crafted into the beautiful pieces of brightwork found on every boat we build. For example, the windshield on a Runabout is truly a work of art, a fine piece of furniture that’s built tough enough to withstand the chance encounter with a cresting wave crashing into it. The exterior teak is finished with a traditional tung oil varnish, applied one coat at a time and hand rubbed between coats for a finish that must be seen to be appreciated. The process doesn’t end until our varnisher is satisfied that the grain is filled to perfection, usually requiring upwards of 12 coats. It’s no wonder these Downeast style boats turn heads in every port.

Our Craftsmen

"It's in the details." That's what you'll hear time and again about CH Marine's reputation for building distinctive yachts. From the custom made type 316 stainless steel chocks which are hand polished to a mirror finish to the unique folding cockpit steps, it takes a trained eye to spot the hundreds of small details our craftsman build into every boat. CH Marine craftsmen and women take immense pride in every classic boat we build. It's not uncommon to see a few watery eyes when a new boat leaves the shop. Such is the dedicated nature of our artisans. Because we build each boat on a semi-custom basis new owners are welcome to stop by during the building process. Many of the unique features found on our boats were born from the requirements of experienced yachtsman.
