About Us

Stephenson marine has been in existence (at the time of writing) for over 25 years and in that time has become synonymous with Kingswear, Dartmouth and the river Dart.

Now run and owned by Rob Hingston, with assistant engineers Dave, Matt and Poppy the dog - we're standing by to assist you with your marine engineering problems.

What Our Clients Say

After an unexpected engine failure we flagged down the patroling Stephenson Marine launch. Within 30 minutes our engine problem was diagnosed, fixed, and we were underway again.
