Ultimate 420 Aluminium RIB



The Ultimate range of lightweight aluminium RIBs is perfect for anyone looking for a high quality RIB with all the advantages that an aluminium hull can deliver; lightweight, durable and extremely strong Constructed from 3 or 2.5mm marine grade, powder coated aluminium and featuring a full length keel guard the Ultimate Aluminium is the perfect recreational family boat.

Each model is equipped with a double floor which provides a flat, wide deck space that is covered with anti-slip EVA pads for total comfort and grip. The double floor also allows for cables and fuel lines to be passed under the top deck again keeping the deck space clear of clutter. All models from 300 to 420 also come with a double front box for anchor and removable fuel tank storage. Smaller models have a single locker.

The large weight savings over an equivalent GRP Hull delivers more economic running costs as well as the option to use smaller engines whilst still delivering still impressive payload capacity.

All models feature an integrated fuel tank built into the forward bulkhead locker.

The Ultimate is available in either the highest quality PVC or Hypalon fabric.

There's also the possibility to fit Ultimate Seat Pack our Aluminium double Jockey Seat Console as an optional extra.

NB: featured boat shows the Hypalon option - PVC material is one shade lighter grey.
