This 12.5m aluminium hybrid electric passenger ferry was custom designed for the rivers of Kashmir in northwest India, with construction about to begin at Knowledge Shipyard, India.

The vessel meets a strict dimension specification of low draft (0.6m), length, beam and air draft (only 2.25m) to ensure passage through shallow channels and low bridges.

Propulsion is via two steerable electric pod drives, which propel the vessel to a little over 8 knots for over 2 hours on battery alone. Where charging stations are far apart, an efficient onboard generator provides extended range.

Inside the FRP passenger saloon there is comfortable seating for 20 passengers, including wheelchair access.

Jayden was recently in Tasmania and was able to visit the Tasmania Police 25m patrol vessel “Van Diemen”, which is certainly a standout in the marina.

Van Diemen was designed by us in 2022-23 in close collaboration with Tasmania Police, and built by Fine Entry Marine in Geraldton, WA.

Jayden dropped into Ali & Steel Worx yesterday and saw the Dambimangari Aboriginal Corporation ranger vessel "Manambadda" in for a refit and running repairs.

"Manambadda", meaning warrior in the Worrorra language, is an aluminium 9.3m Air Rider in NSCV 2C survey. Originally launched in South Australia as a fishing vessel in early 2009, the vessel now performs ranger duties is northwest WA.

2026 marks 30 years since we designed the 60' cray boat "En-Rybo"! These photos are from the original sea trials and are still some of our favourites.

When Jamie O’Byrne ordered “En-Rybo”, the order was definite … High bow freeboard, good beam and excellent load carrying.
In 1996, this was the first of many GMD designed aluminium cray boats professionally assembled by Fine Entry Marine of Geraldton W.A.

“En-Rybo” (being the O’Byrne name spelt backwards), raised the standard for aluminium rock lobster vessels when built in 1996. The incredible flare and deep forefoot made for the ultimate fast lobster vessel, but combining that with twin keels, she set new standards in following sea tracking and safety.

There’s not much that this one hasn’t been through, all with flying colours.
