The new MMA training vessel, due in 10/24, will use electric power to run its engines when its on the dock.

Uh, it’s got 4x Wabtec V16 diesels that are allegedly setup in a way that they burn clean enough to not require typical SCR or urea emissions equipment which saves quite a bit of space plus doesn’t stink like shit.

Those are all bolted to Cummins generator sets; the propulsion itself is all electric but you need a way to produce said (fuckload of) power to spin the prop and run everything else on the ship

It’s going to be vastly more efficient than the current one but I don’t see how they’ll be using electric power to do anything non-standard on it

You know if it'll still have Variable Pitch Propellers?

I still feel like biofuel is the way to go for boats/planes and heavy machinery.

i’d be interested to see how long an electric boat could last

The US currently dedicates~40% of corn, and a similar fraction of soybean oil to biofuels already. So there's limited room to expand biofuels to support all the applications that we currently use liquid fuels for. My expectation is that shorter-range boats, intended for single-day travel, are likely to be electrified.

This is all true. It seems like ferries would ideal for being electrified, considering they don’t go too far and are on a set course.

I’m still hopeful that we can manage to build a better biodiesel infrastructure to help support machinery/boats/planes. But everyone may keep pushing electric-powered transport

Agreed- the endurance of a 36’ lobster boat depends on the energy density of diesel

About halfway through their traps then they'd have to for a real boat to tow them in 😂 (joking I have no idea)

outboards? I wonder what the battery would cost to produce all of that torque for 10 hours. Boats are heavy with lots of friction.

It would seem to me that hydrogen is more likely. I wanted to convert my small sailboat to electric and it’s still a tough sell, even being not that expensive. I will say I love my electric dinghy motor.

I could not imagine being the first guy to pull up to the wharf in a electric lobster boat. You would be roasted to a crisp!


Chessie-System t1_j8ekjf3 wrote

Lobster boats can use hundreds of dollars of diesel a day. If electric is cheaper, I'm thinking they'll be ok with some teasing.

Electric boats arent gonna be popular for a lonng lonng time. Huge strides need to be made.

It’ll be like 100% autonomous driving, “five more years away” indefinitely

Well in cali its already happening but not in maine which is awesome for us
