Ribcraft Number 4 “Thumper” was completed and handed over to us in May 2019. Although an identical hull to Grumpy and Ariel, Thumper has a shortened cabin, to facilitate More aft deck space for diving and ROV projects. She also has twin Yanmar V8 inboard diesels coupled to Duo Prop Yanmar legs.

A dive ladder, umbilical horns attached to outboard of the transom and large davit arm all lend themselves to dive and ROV ops.

75% of the seating is modular and can be removed to facilitate different scenarios inside the cabin such as work stations etc.

Thumper has daughter craft capabilities and can be slung and lifted onto mother vessels.

Coded to Cat 2 / 60 Miles from a safe haven, 12 passengers and 2 crew, IMCA/CMID compliant.
Thumper is Road Transportable on our specialised articulated Truck and trailer and requires a movement order.
Traveling Hoist, or Crane Deployable, from Transport to water.
