Completely redesigned for 2021. An overhauled helm with a centrally mounted Raymarine display puts you in complete control. Slash-cut tubes make the ride look and feel even sleeker. And larger bathing platforms and extra grab handles make boarding and bathing a breeze.
The DieselJet 505 excels in both comfort and practicality. Its ingeniously designed layout offers ample room for eight passengers to relax while ensuring there’s plenty of storage space for their belongings. A sense of security carries on inside the boat, with handholds and leg bolsters to keep you firmly in place so you can focus on just enjoying the ride.
Add to that new Silvertex upholstery and space for another passenger to ride in ultimate comfort, and the best diesel tender just got better.
DieselJet 505 in Action
Flexible height
Folding helm and windscreen.
The DieselJet’s folding helm and windscreen - as well as its optional single-point lift - lets you reduce the boat’s height, so you can say goodbye to those precariously tight fitments.
Clear instrumentation
We’ve made the DieselJet’s instrumentation clear, simple and elegant - so you always know what’s going on above and below water.
A Raymarine 170 helm display, depth sounders and chart plotters make navigation easier than ever, so you can be supremely confident on the sea.
Always sitting comfortably
The DieselJet’s seating isn’t just comfortable...
It’s leg bolsters and abundance of handholds ensure you feel more secure, so even nervous passengers feel safe onboard.
Manoeuvrability in all conditions
The DieselJet’s unique hull, control system and pump deliver pinpoint accuracy at any speed.
Handle small spaces and delicate manoeuvres with confidence. Or open up the throttle and feel the thrill of straight-line speed and precision turns.
Easy boarding
Stepping aboard couldn’t be easier.
With multiple boarding points, gripped step pads, stainless steel boarding pole and optional LED deck lighting, stepping on and off your tender has never been easier.
Space, stability and control
The DieselJet offers maximum space for comfortable seating and practical storage.
Its centrally mounted engine and inflatable tubes sit lower in the water, so whether you’re taking hairpin turns or serenely boarding at the jetty, the DieselJet is always at your command.

POWERBOAT AND RIB
“The DieselJet 505 is not just built to be a workhorse, as it looks good in the process.
It is ideal for guest transportation and fast-paced water sports, while still enjoying the low draught of a jet drive when slipping onto a secluded beach.”
