Custom Boatbuilding

Our Southport 30 is a custom built boat. What do we mean by a custom-built boat? We work with you, the client, to ensure your complete satisfaction.

As one client related: "We needed the boat's cabin roof raised six inches to accommodate taller pilots. We have been extremely happy with our working relationship with Doug and Sharon Goldhirsch."

Our skills in building world-class quality boats are not limited to the Southport 30. We custom build boats from the keel up (or "from the plans up"), fit out hulls made by others, and perform major refits of existing boats. We always use the finest modern materials and methods.

Southport HB Line

In 2006 we will be introducing a new line of traditional powerboats built in fiberglass. Be sure to check on the progress of our Southport Handy Billy Line.
