When did common sense become an "extreme view". what use is a boat that can only do 30miles from one specific location. I feel like I'm living in some bizarre Utopian dream where all common sense has left reality when I read this thread.

I can fuel up the fishing boat in my backyard and go further than 30miles. And that I can fuel up anywhere in the world. This is just nuts.

What they should be doing instead of criticising EVs is praising them. They should repeatedly post on social media that EVs are the greatest thing since sliced bread; that they are vastly superior to ICE vehicles and that driving one makes you irresistable to the opposite sex.

They should be encouraging everyone to get rid of their ICE vehicle and buy an EV.

Every time they persuade someone to convert, that reduces the number of ICE vehicles on the roads. Fewer ICE vehicles means less demand for petrol and diesel. Less demand means lower prices and less likelihood of fuel shortages.

Petrol/diesel lovers are shooting themselves in the foot by criticising EVs. They would serve their own interests better by convincing everyone else that they should buy an EV.

How long have I been saying this! Every EV is more diesel/petrol for everyone else. And more pressure off for emissions reductions! Leave people with old cars to suffer!

I've been questioned in here as to whether I'm delusional about how many SUV/ DC's make up brisbane traffic. Riding home from work and I thought perhaps I might save this for you all.

There are still cars in brisbane - but not very many of them. The proportion of DC utes is far less than my street. Might be a more wealthy area.

But can your fishing boat carry 2100 passengers and 225 vehicles from one country to another at 25knots 4-6 times a day across a very shallow water body (less than 2m depth in some places) for the next 30-40 years?

This water crossing which this ferry has been designed for carries several million passengers a year. It saves doing a 500km trip by road and only takes 1 hour 15 minutes.

The actual range of the ferry is about 90km, but it only needs to do around 55km per trip and can be fully recharged in the turn around window between trips. There is no benefit to carry extra weight to go longer distances.

Comparing your fishing boat with a 14,000 gross tonne ship is a pretty extreme viewpoint.

Not at all. Its nuts that a 14,000 tonne ship only has a 30mile usable range. What a pointless useless piece of junk. It can never be sold when they realise how useless it is as you can't just fuel it up and move it .... and anywhere it goes, needs massive charging infrastructure to get the junk even off the docks.

Just nuts... laughable... every other ship in the world would be capable of travelling the entire world quite easily.... It defies belief that anyone thinks this is a "good" thing and the future of anything.

It is purpose built to do just that job,nothing else.

What happens later on if they want to get rid of it who knows.They probably haven't thought of that,maybe by the time end of life appears it will be scrapped.

There are many EV rigid trucks around similar,just built to do short trips around town.

Interesting as Rottnest is just 19 km off the coast of Fremantle or about 22 from Hillarys.


The ferry is purpose‑built for Buenos Aires ↔ Colonia (~50 km) and Buenos Aires ↔ Montevideo (~200 km) I think. The cost to run would be a faction of the fuel cost even pre-Trumps new April fools day events Assuming 100–200 nautical miles range Rotto may see some quickly or tickets will be MUCH higher?

That is right. It is purpose built to replace the last ferry which has operated the same route between Buenos Aires and Colonia del Sacramento for the last 34 years (also built by Incat). It is either 6 hours by road or 1 hr 15mins by ferry.

Also as it needs such a small draft, there is little to no traditional RORO passenger ship of the same capacity that could make the same crossing without running aground. Most would be too heavy and have at least a 5m draft. Incat specialise in light weight low draft ferries ideally suited for this specific route.

Short haul high capacity high speed ferry routes are quite common in Europe so they could easily find a new buyer for it. A Denmark ferry company has orders for 3 from Incat, but there are many more ferry companies that could use the same type of ferry.

The other option if the owners did need to sell is it could be converted to be powered by Diesel Hybrid or LNG gas turbines using the same electric propulsion system. The current battery rooms would be converted back to engine rooms which was the original design. It would just lose some dead weight carrying capacity and cost a lot more to operate, but when then give the extra range if needed.

Incat are also leading the way in designing and building diesel hybrid electric propulsion ferries which can later be converted to full electric when battery technology improves for longer range, all based on the learnings from Hull 096.

Within in the next 10 years they expect the range potential to increase to over 600km, which would then make it possible for longer range Diesel hybrid ferries to be converted to full electric - probably around the same time the diesel engines are due for their first major overhaul.

To not be proud about a Tasmanian manufacturing success story which is creating employment opportunities in a growing global market is pretty sad.
