What about forgetting the log book altogether and just living in the moment?

I used to regret not getting a bigger engine for my 57 x 12ft sailaway because the 55hp engine seemed a bit underpowered. However getting the 19 x 13" prop repitched to 18.5 x 11.5" increased max revs and made all the difference. Although the engine still looks small in the engine hole it now produces plenty of power.

Wasn't the entire goods carrying narrow boat in effect a well deck with a canopy over the top? Ok there was no raised deck above the hull unless you include wooden boards and it wasn't self draining, but you get my point. Well decks are a modern invention as are full length cabins. No narrow boat with a full length superstructure, or anything longer than a small back cabin should in any way be described as traditional.

Although this case is still being investigated, it happens most winters, usually as a result of people falling in under the influence of alcohol and not being able to get out. We had a floater come past the mooring once at Brentford.

I think most stoves on boats, which were never destined to work with such short flue/chimney lengths, often suffer from poor draw. My big Morso Panther has a 6" dia flue. I think there's a relationship between stove size, flue dia and length because when I open the doors smoke comes into the boat. I solved the issue by pulling forward the baffle plate by half an inch to leave a gap at the back. This diverts the smoke to the back of the stove rather than the front. The airwash might not work to keep the glass clean but it never worked before anyway.

Yes, that's exactly what I do. Mind you, I used to do the same thing with my old Trojan lead/acid batteries, even when they were down as low as 12.3v. Never had any problem starting the Webasto Thermotop C. As I've said before, I think the whole "vehicle spec diesel heaters shouldn't be on boats" mantra may be a bit overblown. Since you shouldn't be taking LA batteries below 12.2v anyway, is keeping them above 12.3v such a great difficulty?

Yes, there are many benefits to LFPs over LAs including the longer cyclic lifespan and enduring capacity as you've said. I'm sure if you work it out over say a 10 year lifespan, lithium batteries will be cheaper than the equivalent LAs, even with the extras for installation. The other benefits: Charging itself is more or less linear, so no drop in amps accepted by the batteries as they charge. For the user there's no need to charge to 100% SOC which is always such a bane of LA battery charging because of the reduced current going into the batteries as they get charged and which accounts for a lot of fuel wastage if stationary charging in winter with an engine or generator. At the other end you don't need to start charging at 50% SOC and can safely discharge until 20%. And because the LiFePo4 voltage range is higher, even at 20% SOC battery voltage will be around 12.8v so all your 12v onboard equipment just works better.

Yes, me too. Once I moved to a new mooring without shore power Lithium made perfect sense. For off-grid liveaboards lithium batteries are a no-er.

That was my original thought too, but then I thought perhaps lithium batteries aren't suitable for everyone in all situations, and even though LiFePo4 batteries can now be bought as cheaply (or even cheaper) than the equivalent lead/acid batteries, the installation is more complicated and expensive.

So what did you do with the 3 lithium batteries you bought?

1.69 kWh generated today with 910w of panels. These sunny winter days might not happen that often, but they happen often enough to make being able to angle one's panels worthwhile.
