Would you guys ever consider a hybrid performance boat?

**Chaz** · 06-16-2021, 08:40 AM

Maybe they can make one with a speaker that goes ..... Vroomm-Vroooooooom ..

Instead of sounding like my wife's blender ...Whhhuuurrrrrrrrrr ..

Would I consider an electric boat? mmmmm (about 10 seconds time gap) OK, no thanks, don't want one...

...hybrid performance boat is an example of an oxymoron...

Also, as for the arrangement, the big Duffy had a big 96 volt motor on a standard inboard shaft arrangement. The smaller 18's and 22's have the Duffy power rudder... a rudder with a prop coming out of it. The lower leaks water in, it's $4500 to replace..... no fixing it. All pretty much 6 - 8 mph boats......

About 5yrs ago there was a surge of these stupid things putt- putting all over naples Bay and ft myers. Every yuppy lib HAD to have one because it was healthy for seagulls....or some crap. Now I don't believe there is even one of these retarded things left running.
No, I wouldn't consider an electric boat....I won't even get on board with fly by wire

Wait... you don't ever go on airplanes?

What I'm driving at, is that fast boats are rad, but... if you look at the amount of time actually spent going fast... versus how much time it's on the water, it's probably not that much. At least in my situation; I'm sure some people are driving hard for hours at a time.... but I'm wondering if you looked at stats from all high perf boats, what percentage of the days they're actually being used, are they even using WOT. 5 minutes? 10? 30?

Idk.

Batteries cannot compete with gasoline in terms of energy storage per pound... but maybe they could hold enough juice to satiate high speed bursts, then rely on ICE for gradual charging in between runs?

Not similar , an exact copy .. sans , you want to charge on gas .. they did it with diesel . Get stuck in the Gulf Stream on 0 volts in a "summer squall" and yea , you'll think someone is tryin to kill ya ... Too bad you don't have enough battery to call for help .. Mayday coast guard station Ft.Pierce .. this is the EV Dip **** idea , I lost track when our battery died .. I think I'm bout 18 miles off your coast .. please come get me before I crash into Savanna Georgia , up side down some time tomorrow .. EV Dip **** idea this is CG Ft. Pierce .. we are sending out our EV Helo out to rescue you ... soon as we charge the battery ..

Doesn't matter how many hour's , minutes one spends at high speed. It's that the boat will do it at the captains discretion .. as apposed to layin the stick forward of a wet noodle .

In the end , it looks like it's gonna be gas powered , with a ton of BS that's not needed ...

I see you live in Millhonkey ... I get it now

So have any of you driven an EV yet?

Why do you ask ..?

Do they carry gas generator's with them too .. spare gas cans .. ???

My cross the skreet neighbor ain't home from work yet , maybe his battery died ..

but I'll show ya the car when he gets home ...

In the mean time , take your's and try to knock my mail box down .. it's the
1.750 x .134 wall ..ladder bar in the middle .. tell me how much it cost's to fix your EV , in-bred import ..

Gee, you're lucky not to have that ugly mailbox in front of your house

I ask because I grew up with V8 musclecars and stuff, and the INSTANT TORQUE of the model 3 I rented on a trip was just insanity... obviously the biggest issue is range on a boat, since batteries are so heavy, but I see a few benefits with the hybrid model:

1. Instant torque (duh), and probably way more than most comparable ICE engines
2. You could have a direct drive, 1:1 gearcase; could be WAY more hydrodynamic without the need for neutral/reverse. Could be a gearcase like my quickie on the KG4 I'm finishing up for my hydroplane.

So more torque, less drag on the gearcase, could be a totally nutty level of performance, just... not for a very long time. Hence the small ICE to recharge while you're swimming or chilling on a sandbar or getting drinks or something.

Also, idk if you saw the news, but the new Tesla plaid runs 9 second 1/4 miles.... easily. It's now the quickest production car in the world, excluding the experimental rimac. All those carbon fiber bodied exotic cars? Not as quick. Just wild stuff... wondering how this would translate to marine market, and the only way I see how is with a hybrid/piggyback generator, otherwise the weight penalty would negate any performance.

No possible way . If it doesn't smoke and have a high RPM powerband I don't want it .

**WavetoWave** · 06-17-2021, 06:06 PM

A mild hybrid would work great. I've mentioned it in a couple recent articles. More electrics are coming on the market but they are poorly designed and ungodly expensive. Most use the Torqeedo, BMW i3 derive battery.

Mild hybrids are great because they don't cost much, have no need for charging and assist the gas motor to make more power. And, can be run on pure electric at slow speeds, around the marina, slow speed zones etc.

Yes, electric motors are insane, the power and efficiency is incredible. A really efficient hull, like an Allison or STV could run with a battery in place of the fuel tank and probably get decent range. The battery, inverter etc would cost a lot. The weight distribution would be tricky.

Taking an existing outboard and removing the powerhead, replaced with an electric motor has been done, not too difficult.

With electric you can get out of the marina, then pull the sails up till you get back to the marina and turn the electric back on
