Power busbar


One of the things important for electric drives is the power feeding the motor. The EU and US Coastguard have produced a lot of new regulations for electric boats and we have been busy reading them and developing the systems to comply with all the regulations.

Firstly all battery banks must be able to be isolated with double pole isolators. Secondly they must all break down into 48v banks. Thirdly you must not connect them to earth/ground. Fouthly you must monitor and alert the user if there is earth/ground leakage...

I must admit that to start with I thought they were a pain, but having developed them I now realise that they really help and have found none of them that are un-necessary.

End users, of course, are not really interested in complexity. They want it simple. So I have designed a PCB to integrate all the power control systems into the touch screen controller. Worked first time... well, actually second time but I was thrilled to see how easy it makes it for normal sailors.

No sailing... being a Grandpa

I've just spent the last month with absolutely no sailing. That I missed.

BUT... I have been in the UK with my son, daughter-in-law and... wait for it... my new grandson. It kind of makes up for the lack of sailing!

So when will I get a chance to teach him to sail?

Another short test of the display for the electric motor.


A short test of the display for the electric motor.

OK, I admit it we did raise the sails and sail for a very few minutes. But sadly it wasn't long enough!

And... you've learned we test on real boats not just in the workshop!
