Havoc Boats i beam ribs

I-Beam Longintundinal Ribs

Our patent-pending I-Beam ribs are a crucial piece of the foundation of this boat. This innovative design creates exceptional strength and virtually eliminates flex in rough water. I-Beam rib technology is one of many reasons we confidently stand behind our products, because they continue to pass every test.

RDBST Performance Transom

Performance Transom Cut-Out

Our innovative transom design channels more water to the prop for increased efficiency, reduced drag, and increased performance. This feature is found exclusively on our RDB family of boats.

MSTC Rear Seating

MSTC Rear Seating Storage Compartments

The rear bench seats each have storage compartments underneath, giving you maximum storage and organization to keep the floorspace open. Each heavy-duty lid is just as durable as fixed benches for sitting and standing on the rear deck.

RDBST Mod 40 Details

The RDBST Mod 40 is the main model we run in regional boat racing competitions. Several design features allowed us to trim weight without sacrificing durability, including 80-gauge aluminum, “hat-channel” horizontal ribs, and perforated mesh floor. B-Scott and the Havoc team tested the Mod 40 extensively during the 2021 competition season and earned the high points honors in the 130 Class. If you’re looking for a rig to run a 660 race, rip it up at the sandbars, or just be the first to the hole, then the RDBST Mod 40 is the boat for you.
