    I went icebreaking in my GRP last winter-- seemingly unscathed from it! Then again she is a bit of a tank and I'm sure there has been thicker ice in the past

    how much

    I would have thought Redhill would be the cheapest on the Soar. Sounds about right price wise

    Scruffy Dawncraft 25 project boat - Should I buy?

    There's a Dawncraft 27 that's just become for sale on the Dawncraft Owners Facebook group that seems to be a really good bet. There's also a 25 on Apolloduck for £250 that would be a serious project.

    what happens to abandoned boats?

    On a steel Hull with Ply topsides it'll pretty much always leak from somewhere as they expand at different rates. Ply Hull is doable but surprisingly expensive and you would havd to design rubbing strakes carefully as wood really suffers against concrete banks and locks. Go GRP, they're great!

    Transport Boat River Soar to London

    I do indeed if its the 57ft blue semi trad that was for sale in Barrow last week. I speculatively went to look at it as the owner was considering a part ex and thought I might be able to be cheeky and swap my cruiser for a narrowboat of roughly equivalent value. The engine was very low on compression and produced a lot of blue smoke- pointing to a worn bore. Of course, it could be a completely different boat and the engine could last the journey no issues at all, I'm not a boat mechanic. Anyway, whatever boat you've bought OP, welcome to boat ownership!

    Transport Boat River Soar to London

    It's not the blue one with the Lister single cylinder engine is it? If so, absolutely no waaay will that make it to London under its own power.

    A genuinely silent generator

    I do have 340W of solar (not massive I know) and that does do almost all of my charging in summer but struggles over winter (as all solar does). I could, but I work long hours (own company) so running engines between the 8-8pm curfew can often be tricky. Seen as i'm only aboard for a small portion of the day my electricity usage is very minimal so one of these batteries (or similar) combined with my solar and occasional running of engines should work for me. I've made my converter circuit and i'm just about to press go on buying one. Not the case for a lot of people, I know, but should work for me. I shared a lock with the people who bought yours! They were just off to have a rubbing strake replaced. We compared notes... They are superb boats

    You can charge from 240v, I believe you can also charge from 12v (dunno though) and you can definitely charge direct from a solar panel with no charge controller required. I probably wouldn't usually charge off my inverter when cruising but no reason why you couldn't.

    A genuinely silent generator

    A KISS guide: The "Lithium Generator" as in my link (and in the links of others) has three outputs; USB (5v, for phone charging etc), 230V AC ( limited to 150w so not especially useful) and crucially 12v. The device is effectively a big battery with various protection circuitry on it that enables it to be charged up safely from mains and to output the three voltages. Into the 12v output of the "lithium generator" you would plug in a boost converter. This is a little gizmo that takes 12v and transforms it into 14.4v for battery charging. I would then propose to plug this into an Anderson plug (a type of high current waterproof plug often used to connect winches) which would be connected to the same terminal as my alternator, so to a battery monitor it looks like the engine is running. It wouldn't be permanent, I plan to disconnect the "lithium generator" when flat and take it into work to charge. It's not very big so will easily sit in a rucksack. In my charging routine it'll basically do the job that solar would in summer. Hope that helps!

    Hang on, two lithium batteries in parallel each rated at 150wh gives a bank of 300wh, which is (with losses chucked in for good measure) 20ah at 14.4V isn't it?

    A genuinely silent generator

    Had already clocked that, but it's that last 5% (or 10% with two of them in parallel...) that's the most elusive as I know you know.

    Multi-fuel Stove

    My boat currently has a machine mart 8kw stove in it which is : A) ridiculous overkill for a 32ft narrowbeam Absolutely deadly in my opinion as its so poorly made. Boatman stove on order and hopefully coming next week so I can scrap the hideous poorly made death trap

    A genuinely silent generator

    Evening all, I've had a bit of a brainwave... One of these popped up as recommended for me: https://www.amazon.co.uk/Portable-Generator-220V-240V-Flashlights-Emergency/dp/B07H3X4MLL/ref=sr_1_1?ie=UTF8&qid=1541017601&sr=8-1&keywords=lithium+generator It's a sizeable (but portable) lithium battery pack, a bit like the ones many people have to recharge phones only a good deal higher capacity (claimed 150Wh) and with the all important 12v output. I'm able to charge it up at work no bother, am I right in thinking that if I connected a boost converter set to 14.4v to the 12v output (along with a volt meter and ammeter) I could do a tail current charge on my batteries? If my batteries were below 80% ish discharged i'd give the engine a run first to do the heavy lifting, but rather than sitting with the engine running annoying all my neighbours it would be ideal to top 'em up with this. (should add, 220ah battery bank, low electrical usage, on mooring without electricity hookup)

    Lithium battery project.

    https://www.alibaba.com/product-detail/Rechargeable-12v-100ah-lifepo4-battery-for_60215699754.html?spm=a2700.7724838.2017115.44.211c117fVbOfw5&s=p If the cost of batteries for lithium is off putting then you could always go Chinese. While completely different I've been very impressed with cheap LiIon 18650 cells from Chinese manufacturers, and almost all of the safety concerns with (potentially) poor quality cells can be mitigated with thorough control circuitry, much like the OP is doing.

    More GRP Cruiser questions

    When I bought my GRP boat (Highbridge 32) I asked myself "what will a surveyor actually find that I don't know already" and opted to not have a survey. Touch wood all still OK!
