Your Vision

Knewstub Marine comprises floating pile drivers, deck barges, pontoon boats, various small craft, and heavy equipment.

We specialize in open pile docks, boathouses and boatlifts, and waterfront development.

We are able to build anything from simple docks all the way up to fully custom boathouses.

We’d love to discuss your current situation today!

See Our Work

We provide and install boat lifts for every possible vessel, from a 30 pound canoe to a 30 Ton power cruiser with roofs over, if desired, to suit the owner’s style.

When waterfront erosion is a problem we can reinforce existing or build new seawalls to keep the valuable shoreline from washing away.

Often waterfront property is not easily accessed by land so we bring supplies, materials, heavy equipment, or whatever might need to be moved by barge to the owner’s waterfront site.
