Continuous: without interruption Cruise: cruise So yes. Interestingly, whilst most CCers remain static for many days, we met a live aboard chap on the KandA who was a bit like us - got itchy feet if he stayed in 1 place more than a day and tended to cruise every day. And he is the only person we’ve met who has lithium batteries! so can you point me to where it mentions anything about continuous cruising in the waterways legislation? No I can’t, because it doesn’t, as we both know. I am unclear why you are throwing waterways legislation into a conversation about batteries, seems entirely irrelevant. Oh well, unless you have a massive chip on your shoulder/bee in your bonnet/devastating feelings of guilt and lack of self-worth I suppose. continuous cruising is a term I use for someone who cruises continuously. Obviously! Which is what we tend to do when we are on the boat, ie we cruise typically 7 or 8 hours every day. As opposed to other people who might cruise 1/2 hr every 14 days. For the former, lithiums don’t present that much of an advantage. For the latter, they do.

A Canadian company has also sorted out the overheating problem as well and at the same time trebled the capacity! If true it will be my buy of choice for the bathtub. Interestingly the Fisker electric car uses Graphine batteries which they claim are far better than Lithium. What I like about all this stuff is the speed of advance for a couple of hundred years we have gone nowhere and now batteries that might last us a lifetime with rapid charging are within reach Could that be ReliON they have solve the overheating problems etc www.relionbattery.com/The small (7 to 10AH) LiFePO4 batteries one can get for gliders these days have a thermal shut off/safety device inside. If the battery core temperature reaches 80C, it releases a chemical into the electrolyte which neutralises the battery. Of course this trashes the battery completely, but that is better than a fire!

From the little I have been able to glean it is done by the BMS that comes as part of the battery not an addon, when the temp rises too much the battery ceases to take charge until it has cooled down. They have also restricted the maximum charge rate on the battery to 100A. Which probably does more to stop the temp rising than anything else. Thus the battery is not trashed.

The batteries I’m thinking of have a built in BMS, but also the ultimate protection of the neutralising device. I suppose additional safety is a good idea for aviation use since the consequences of a fire are so serious. Of course the BMS should prevent overheating, but presumably BMSs can ultimately go wrong. Plus of course it looks good to sceptical people who have heard about lithium battery fires (nearly everyone considering buying one, I suspect). www.navboys.com/products/batteries-and-chargers/lifepo4-batteries/

So "proper' continuous cruisers cruise everyday do they? Isn’t that what continuous cruise means? No. Continuous cruising does not require daily movement. "Continuous" means "without interruption" and on that basis could be interpreted as requiring movement 24 hours a day. However "cruising" means "to move in a desultory manner without schedule or destination" and movement according to the CRT guidelines on such matters satisfies both the legal and grammatical definition.

Continuous Cruising is merely two words put together by BW with the intention of causing confusion, and consequently promoted by people with very tiny dicks.

It find it amusing that one can say “cunt” or “twat” on here and nobody bats an eye. But woe betide anyone who says “continuous cruising” in a way that the great unwashed find inappropriate!

So I wonder why you did that?

I prefixed it with the word "proper" because many people who refer to themselves as continuous cruisers, are anything but that in any normal sense of the phrase. The people who are continuous cruisers who are for example static for 13 days and cruise for a short period on the 14th, are the sort of people for whom lithium batteries would hold a big advantage. I used the word "proper" to differentiate between them and continuous cruisers who cruise continuously (ie every day), as for them the advantages of lithium batteries are significantly less. So "proper" in the sense of more closely resembling an everyday interpretation of their chosen terminology.
Lets say you asked the man on the Clapham Omnibus which of these two groups, both of whom called themselves continuous cruisers, were in fact the "proper" continuous cruisers: The chap who cruised for a couple of hours 1 day every 14 days and remained static the rest of the time, or the chap who cruised every day for 8 hours. What do you think the answer would be?

I think anyone who asked that question to stranger on a bus to Clapham would probably get stabbed.

You aren't half long winded you know Nick. Far to many words, your so full of yourself you have to let it out is that it?
