What Harrison Dock Builders does

Harrison Dock Builders, operating under the trade name HDB Marine, is a custom marine dock design, manufacturing, and installation company founded in 1983 in Harrison, Idaho. The company builds residential, commercial marina, and government/public-access dock systems using welded 6061-T6 marine-grade aluminum for gangways, steel frame construction for dock systems, poly float dock technology, and custom floating wave attenuators. Its product portfolio spans floating steel docks, fixed pier docks, timber and cedar-log docks, boat lifts, ADA-compliant gangways and bridges, multi-purpose deployable barriers, and DIY dock kits, along with accessories such as decking options and fabric slip covers.

The business operates a project-based, quote-driven model: every dock is engineered to site-specific conditions, with revenue generated through one-time hardware sales, turnkey marina contracting (consulting, design, engineering, manufacturing, installation, and permit assistance), and recurring boatlift removal/reinstallation services. Customers include residential waterfront owners, commercial marina operators and waterfront developers, and federal/state/local government entities — the latter served under GSA Contract Holder status. Go-to-market is enterprise field sales with a 'Request a Quote' website funnel, project galleries, and testimonials as the primary marketing assets.

The company maintains its headquarters in Harrison, Idaho and a marina operations location in Coeur d'Alene, and advertises service across North Idaho, Washington, Oregon, and nationwide for government and large commercial projects. It is privately held, founder-operated, and has been active in marine construction for more than 40 years without disclosed institutional backing or M&A activity.
