The direct result of close collaboration with OceanHunter, The IS 400 Spearfisher® is the ultimate boat for Spearfishing enthusiasts.

Senator’s Spearfisher® combines proven stability plus a raft of clever, fit-for-purpose design features delivering a unique boat, fully customised for the sport.

Special features include higher sides, oversized bow rail, an extra seat along with 2 sliding removable bench seats, 4mm hull plate upgrade, swim-on duckboard, fin & buoy storage plus additional dry storage.

Custom made tie downs and holders for spearguns free up plenty of deck space.

Anchoring is a breeze, and the anchor locker has good capacity – stand directly above the anchor well and pull with minimal effort.

Pontoons add buoyancy and stability, great when entering and exiting the water.

The compact size means towing and manoeuvring is easy.

The Senator

At Senator we measure the true length of the boat, we don’t include the overhangs to make our boats seem longer than they are = more boat for your buck.
