The JMS Naval Architects


Experience Built In

We believe our unique “sea-going” attitude, that places our employees “in the field” and “on the sea” on a routine basis, produces stimulated minds, real world experience, and very practical solutions. We know our customers benefit from this and especially by having access to our wide range of expertise and experience level. We know this because our customers tell us.
