Extra Heavy Duty Series

Electrofishing Boat
The most robust electrofisher ever made, period. The heavy duty hull will provide any scientist with a work platform that will last a career. Ideal for scientists on long field days on large rivers and reservoirs. Large storage compartments, incredible stability, and work space designed for large field crews.

Rugged V-hull boat designed for heavy-duty electrofishing operations in rough water conditions. Available in 18, 20, and 21 foot hull lengths.

Imitated, Never Duplicated

Custom-built from the bottom up, the Extra Heavy Duty Series sets the gold standard for electrofishers. With a fully integrated electrofisher, power generation, and livewell, the EH Series boats can't be equaled by boats built from random parts.

Work Space And Storage Are Standard

The center island design allows for an unprecedented amount of working space. Roomy walkways allow easy access to the full boat length on both sides and the large, stable forward work deck provides room for multiple crew members.

Built To Last

The custom designed hull is constructed from heavy gauge marine grade aluminum for a long service life. The all-welded design combined with hard rivets means your Smith-Root electrofishing boat will be on the water for decades.
