The TDB 21 SeaClass

The TDB 21 SeaClass workhorse gunning platform is back!

 

TDB’s SeaClass models have long been the favorite gunning platform for sportsmen. Olsen Marine continues this legacy using resin-infused construction to make these safe, stable vessels even stronger and more durable, for the heavy loads and tough conditions that duck hunters demand of their boats.

 

The TDB 21 SeaClass fills a need for safely accommodating a large group. With enough room to accommodate 5 hunters, dogs and gear, she is solid, seaworthy and comfortable. She draws only 9 inches when fully loaded, stays steady under shifting weight and rough seas, and is engineered to reach waterfowl in open ocean or shallow water. The flotation is molded into the hull, and the bow is Kevlar reinforced. Whether you are a guide earning a living or someone who wants more friends along for the day, this boat is designed to handle it.

 

The open floor layout makes this big boat feel even bigger. A side console and Teleflex steering are standard. The console houses your electrical panel and electronics, as well as dry storage and easy access to controls and wiring. The massive forward storage area can fit dozens of decoys, or serve as a kennel for a dog between retrieves. She has dual shelving, big enough for magnum sea duck decoys, running down the cockpit sides, with decoy curtains to keep your gear contained. The decoy curtains are made from the same 1000 Denier Cordura that the rest of the blind system, and motor cover are made of. There is no wood in the boat, and all electrical components are top of the line marine grade equipment so that maintenance is kept to a minimum.

 

Our industry-leading technology makes the TDB 21 SeaClass an incredibly useful boat for the winter or summer. The custom construction process we use afford us great flexibility for customizing this boat to ensure it functions exactly as you need it. Olsen Marine has been a custom boatbuilder since day one, so if you have special requirements all you need to do is ask. Contact us with any questions you might have about this legendary boat that is getting better with age!
