Can they Re-Invent Motor Yachting?

[Portofino]

Those SL SX 88,s are popular, there’s one in Antibes and another here in Loano .
The Loano one is floating summer house / water access / toy shed .
It’s the hull form , the dual role that’s the game changer .
Sunseeker and I think Princess with there around 40;m upwards stuff do the same ........
It’s being able to semi D efficiently mid range teens speed economically with the reserved ( hardly used ) ability to exceed 20 knots + always in the back of your mind .

Obviously 10 to 12 knots or lower the fuel savings are massive for the SL , S/ Sker and big Prinys .

Technically they are all planing boats .

With the SL Sx88 the IPS halves the total engine displacement and the twin prop thingy reduces the Hp needed so its carbon foot print is hugely lower than say a Pershing 80 on Arnesons or AB 80 on jets cruising at 37 knots .
No Pershing or AB owners gonna cruise at D speed that conscious decision was made at the buy .

The fuel bills will be lower too for the newer generation of hull form .
This has range implications for the slower boats designed to go mid teens can go 1000 ,s of Miles on a fill up .

Unfortunately, Greta (the darling of the ban everything brigade) made a special point of showing the world that fossil fuel burning boats are a bad thing

so, looks like the solution is cat(ish) hull form mobos doing D speeds only with lots of solar panels, smart generators and el.engines...

Greenline still about or died?

PS. 3full weeks on board my 43ft 12t planning hull mobo, we did circa 380nm and burnt around 700lt of diesel on lowish D speeds (due to either fishing at 3.5kn or blocked watermaker prefilters - had to do 5kn max from one anchorage to another in order to make water...). Did anyone mind, nope!

Did she ?
I did not pick up on that .
Sure land vehicles , ships with food miles and deforestation, eco homes , energy wastage and stuff like that .
You have like I tried to explain strip out red herrings .Leisure boatings effect = negligible .

Here zero emissions ,in every marina .

I don't know, V.
For those of us who aren't teens anymore, the final solution might well be provided by mother nature.
I have a funny feeling that I will be long dead before needing to give up boating for fuel reasons alone...

Exactly and while I go out this morning and do a couple of hrs today with 13 L twin s there’s maybe over 1million VAG com 2,0 TDi engines in the EU in Audi , VW , Seats , etc of which more than 1/2 will have had a run today 1/2 of those in city’s .
I wonder how may 2876 s in marine use are used today in the EU ? Less than 100 boats if that .
Meanwhile on land the same block is in trucks , coaches , and rail cars so 10,s of thousands “land units “ smoking away killing kids and punching a huge hole in the atmosphere = global warming .

Can’t see or feel my 2 hrs worth is influencing anyone or anything.

very true Porto,
however a nicely worded (and pointless) argument will be fired repeatedly against boaters for various reasons among which is jealousy, ease of attacking a small rich market, support from the general public as it sees a badie that wont affect them, etc

When Tesla makes their big electric trucks a success then there will be the ability to have the drivetrains marinised

Don’t bet the family silver on this. With current battery technologies, most of the payload will disappear, replaced by batteries

One of the challenges for emissions on coastal boats is who enforces? In the U.K., and I guess EU inland fuel is 5-7% bio. Coastal and offshore is not. Sovereign countries can enforce in their own waters but not beyond. In any case U.K. has limited resources for enforcement. Currently mostly focussed on patrolling Dover for illegal immigrants. I think we have 2 or 3 patrol boats?

I really like the works of Luca Santella but I keep wondering; how are you supposed to bring the mooring-lines from the stern to the bow on the BGX70?

I would suggest the point she was making was more about aircraft than boats. Logically banning pleasure flying would make much more sense than pleasure boating as far as the environment is concerned.

When she got towed out by electric ribs I think the point was made

Well on a boat of this size and cost, I expect you tip the marineros €50 or whatever to come out in their RIB and hand you the mooring lines at the bow. Failing that I guess you need 2 crew and a boat hook to get the lines past the bulkheads aft. This isnt the only boat which has these issues

Indeed; at least two crew for one mooring line. If picking up the mooring line, without passing it, I assume the boat hook must at least be 4 meters long? (the point from where to pick up the mooring line seems at least 12 meters away from the dock). At least the idea behind the BG62 was not to have crew around; it just seems odd for a product pointing at its practical design.

And yes Greenline are going stronger then ever, but are less hybrid then as @ launch.
I think they sold about 10 of the new 45 which launched in end July before Cannes opened, and it has a hybrid option.

I will add that the batteries thing is a total waste and very bad for the environment, production and dismantling wise. Not during use but to produce.
This a whole marketing B/S and a way to make people spend money. I saw quite a few reviews where producing a mid-size electric car did more harm to the environment that a BMW 5 series with a 3.0 liter diesel engine after 500k mark. The report included damage to the environment for the production the use and the scrapping of the car. The diesel car did less damage.

Hydrogen is the real solution but somehow the bureaucrats in the Western World do not want it to make it work for now....

.

The reality of hybrid boats is that you can only cruise a few miles at dead slow speeds and then, if you want to go faster or cruise for any distance, you have to start the diesel engines. So, at that point, all the electric motors and batteries are doing is adding weight to the boat and increasing fuel consumption. So, if you want to do a bit of green willy waving to your mates in the marina, you leave your berth under battery power but as soon as you're past the breakwater and out of sight, you switch your diesel engines on
