18 Limestone Runabout



Sporty, dependable, and a lot of fun, the Limestone 18 Runabout from Medeiros Boatworks is a small boat that delivers big when it comes to making family memories on the water.

This runabout’s spacious layout makes it a comfortable boat for whatever you need it for, from fishing with your kids or buddies, to picnicking with the family, to exploring the coast on a summer afternoon.

The roomy cockpit and generously padded sleeper seats ensure everyone onboard will be plenty comfortable. And the forward storage area keeps gear organized and protected from the weather.

The solid construction and design of the Limestone 18 Runabout makes it an exceptionally seaworthy and reliable vessel. It planes quickly, handles confidently, and is more than durable enough to stand up to the rigors of New England boating for years to come.
