So today I had to visit Johnathon Wilsons yard in Sheffield, is Son in law Richard runs Finesse boats from there, Richards other business [Racetech] had been making up a sump for me out of two alloy sumps.
Whilst talking to Richard and Johnathon, Richard mentioned that 9 out of the next 10 builds were electric boats, he showed me his drive system which is an inhouse built 48 volt system, it was very impressive and very neat and tidy. Its a direct drive running at 1500 RPM its 15KW constant and 30 KW max,, its a liquid cooled motor with Winston Lithium cells, On one of the boats it was installed with 10KW of solar bifacial for higher efficiency. It seems that rather than waiting for 2025 when inland boats have to be carbon free they have decided to go for it now ie jump rather than being pushed, Richard knows that I have an electric boat so he was speaking to the converted but its nice to know that his customers are forward thinking as well.
The mix of boats was NBs and WBs/very large Briganteens as well

Seems the Sheffield area is a bit of an electric boat hotspot then. 10kw of panels on a boat?

It seems that rather than waiting for 2025 when inland boats have to be carbon free Where did that come from? Presumably that also means no fuel fired heating ie no solid fuel stoves and no diesel or kero systems on inland boats. Brrrr. And no petrol outboards. And no diesel engines. In five years. Hmm.

New boats read this Maybe more people should see this - I'm 'pi$$ing in the wind every time I try and talk about the Marine 2050 Plan
By 2025 we expect that:
i. All vessels operating in UK waters are maximising the use of energy efficiency options. All new vessels being ordered for use in UK waters are being designed with zero emission propulsion capability. Zero emission commercial vessels are in operation in UK waters.
ii. The UK is building clean maritime clusters focused on innovation and infrastructure associated with zero emission propulsion technologies, including bunkering of low or zero emission fuel.
By 2035 we expect that:
iii. The UK has built a number of clean maritime clusters. These combine infrastructure and innovation for the use of zero emission propulsion technologies. Low or zero emission marine fuel bunkering options are readily available across the UK.
By 2050 No non-zero emission boats can be used in UK waters (coastal or inland)

Do you have a link to the source of this Peter, I’m not being pedantic. I’m interested and would like to read the source.

Sorry, cross posted with Peter.

Thanks Peter, I’ll give it a read.

Slightly different to saying "2025, when inland boats have to be carbon free".
I know there are changes afoot and I am the first to welcome them but in five years time most boats will still be propelled by dinosaur oil engines.

I know there are changes afoot and I am the first to welcome them but in five years time most boats will still be propelled by dinosaur oil engines. If you read the original document, ( which I am doing slowly and bit by bit.) They are only expecting a 50% take up by 2050 and fully adopted by 2100. It is mainly dealing with commercial shipping as well, which is funny as most commercial vessels are registered under a flag of convience. So surely any changes implemented would need to be global in reach to be effective.? It has some really interesting reading about the different tech being preposed. Electric boats are only one of the options and the limitations and drawbacks of electrical propulsion talked about are quite telling.

Yes I know what's happening I was just taking up peterboat on his inaccurate comment.

"That's a concept being explored with the Oceanbird, a ship capable of transporting up to 7,000 cars at a speed of 11mph" Never mind boats I reckon if they could explore the concept of limiting the speed of cars to 11mph we might be onto a winner

I did some trials of alternative props on my electric MK 40lb outboard which may be of interest to anyone looking to drive a small boat with a trolling motor.
Magnetic fellow had recommended model aircraft props, so that was part of the trial. I was also interested to find out how increasing the pitch of the manufacturer's prop might affect the power and speed, because when cruising at full power the motor only draws 80% of its maximum rated current. I set up a large circular kids' paddling pool so that I could produce a circular flow, replicating as far as possible the dynamic conditions when pushing my boat. At half and full speed on the controller (an aftermarket Chinese 100A PWM - anything less than 100A burns out rapidly) I measured the speed of the flow using a weighted pendulum suspended away from the motor, and checked how far from the vertical it was pushed. The distances measured are relative and not even proportional - they don't represent anything more than that. The results were interesting: Manufacturer's 2 blade 10" prop ................................... at 15A pushed 6.5, at full power 29A pushed 8 Manufacturer's 2 blade prop with slightly increased pitch .. at 15A pushed 6, at full power 32A pushed 8.5 Aftermarket 3 blade 10" prop ....................................... at 15A pushed 6, at full power 29A pushed 7 Model aircraft prop 10x6 ...............................................at 15A pushed 4, at full power 36A pushed 7 I conclude that the manufacturer's prop is nearly ideal, and a slight improvement can be gained by judicious twisting of the blades under a heat gun to increase the pitch, but hardly worthwhile. No advantage to be gained from the 3 blade prop. The model aircraft prop with very narrow blades surprisingly draws more power and produces less thrust - it is highly inefficient. Sorry, Mr Magnet.
There are many American websites where improving the speed available from an MK is discussed, and the suggestion is always that MK (the world leaders in trolling motors) could do better. In my case they have got it just right - slightly on the conservative side of ideal, and probably allowing the motor to perform reliably for longer.
I may try a further experiment with the pitch increased more but with the prop tips trimmed down to 8", just for fun, and I'm waiting for another aftermarket 2 blade to arrive.
