Boat

RJ 28 and RJ 34

Based in the Netherlands, Alumax Boats builds strong aluminum vessels widely used in both professional and recreational boating.

For the RJ 28, Alumax selected a hybrid configuration with a 170 hp Mercury engine combined with a WaterWorld WW10.0h hybrid drive. With the power of the two WW48-6800 batteries, this setup allows quiet, emission-free cruising when operating electrically, while the Mercury engine provides extra power when needed.

The larger RJ 34 model features a Mercury engine combined with a WaterWorld WW20.0h hybrid drive and three WW48-6800 batteries — offering even more electric range and efficiency.
