R-N-R MARINE

Armus Marine visits Maryland to train the RNR Marine team and coat a flats boat for better performance, protection, and shine. Capt. Ron Coyne, Jr. of RNR Marine saw the value of Hull Pro and put it to the test on a Hewes Redfisher 21. With careful prep and expert application, this flat-bottom boat now glides faster, stays cleaner, and turns heads thanks to a gleaming gelcoat finish.

Flat-bottom boats like the Hewes Redfisher are built for shallow water performance—but even shallow drafts need deep protection. When Capt. Ron Coyne, Jr., a longtime industry pro at RNR Marine in Maryland, saw what Hull Pro could do, he wanted to try it for himself. Armus Marine headed out to RNR Marine to provide hands-on training, and together they coated the underside of the Hewes with Hull Pro. The result: better fuel economy, higher performance, and a gelcoat protected from UV rays, water intrusion, and abrasion. This case study shows how careful prep and expert product knowledge make all the difference.

TRAINING WITH R-N-R MARINE

As a growing community of certified Hull Pro applicators takes shape, Armus Marine continues its commitment to hands-on training. RNR Marine in Maryland, under the leadership of Capt. Ron Coyne, Jr., welcomed the Armus team to their shop to get a firsthand look at the coating process. Ron, a seasoned veteran with years of marine experience, was immediately drawn to Hull Pro’s performance and protective benefits.

The training included surface prep instruction, application technique, and long-term maintenance guidance. With decades of boat handling and repair under his belt, Capt. Ron knew immediately that Hull Pro wasn’t just another coating—it was a game changer for the gelcoat below the waterline. The Hewes Redfisher 21 flat boat became the perfect candidate for their first install.

PROPER PREP FOR PEAK PERFORMANCE

While Hull Pro does not require sanding to bond, sanding the gelcoat before application improves surface adhesion and maximizes durability—especially on vessels that see tough use. The RNR team sanded the entire bottom with 600-grit sandpaper and wiped down the surface with acetone to ensure a clean bond. This level of care in the prep stage sets the tone for a successful coating.

With the hull prepped and dry, the Hull Pro application went smoothly. Applied in a single coat with a roller and tipped for even leveling, the coating locked into the surface and began curing within hours. The end result? A slick, ultra-clear finish that repels fouling, reduces drag, and leaves the gelcoat sealed and shining.

GAINS ON THE WATER: FUEL SAVINGS & PERFORMANCE

Hull Pro isn’t just about the gloss. On this Hewes Redfisher, performance improvements were immediately noticeable. Reduced surface drag thanks to the hard, slick finish allows the vessel to plane faster, cruise at lower RPMs, and enjoy longer range per tank of fuel. These small performance bumps are especially valuable in flats boats, where efficient planing and speed in shallow waters are key.

Flat-bottom vessels are particularly prone to friction-based drag because of their broad contact patch. Hull Pro smooths that contact zone, allowing water to glide over the hull instead of grabbing at it. That translates to both measurable and felt gains for any boater—and on a vessel used as frequently as this Hewes, those benefits stack up over time.
