MtB

I'd imagine like DMR says, there is a lot more to it than just this. I'd imagine the above only applies when it increases the difference in height of the CoG and the CoB. If it reduces it, the boat could become more tender. Also inertia effects need taking into account.

Stand by for a great topic swerve here. I learned recently something that surprised me. I'm not fully convinced yet but it was from a reasonably authoritative source (though not one I can recall right now). Thinking actually consumes energy. Actual calories! Intuitively I've always felt that after a day at my desk doing thinky work (phone calls, web design or whatever, etc) I shouldn't feel as hungry in the evening as after a day out doing proper work. But I often do. Seems as though we can burn calories just by writing thoughtful posts on here. Yippee!!

Taking the old BD3 out of Aldebaran and fitting the Kelvin K1 made the boat noticeably more tender despite the engine being quite a bit heavier. So much so that it was not just me that noticed, but friends and family commented on it who you would not expect to notice. I put it down to raising the centre of something or other. Or perhaps raising the centre of gravity relative to the centre of buoyancy.

That water heater flue looks a right bodge, leaning backwards like that. And hard to tell for sure but it looks to me as though there is a gap between the top of the heater and the start of the flue! IF the flue is actually connected into the flue collar on the heater it will still work fine, but the bodgery in the photo might notbe not a good indicator of the standard of all the other work in the boat. Point of Order, its a galley when its in a boat, not a kitchen. And while I'm on, another point you didn't ask about - the roofline seems to slope downwards noticeably more to the left. The height of the join between the roof, oops deckhead and the left hand cabin side looks about 6" lower than the join with the right hand cabin side. Maybe its just camera lens distortion but the shell looks decidedly asymmetrical in the pic.

Lol I have a Renogy battery. The battery works fine but it drives me nuts to have to re-log into the app every three months, and it won't use Apple Keychain to remember the password! DIdn't realise they have a forum. I'll have a look later and maybe have a moan about this

Too busy posting on FaceBook, probably....

If they did, those spots would fill up immediately and then people would complain about THAT, instead!!

Its still out of the water having just been overplated!

I was so busy Thwacking you I missed that!!!

I'm inclined to think these days that any firm saying you are the only one with this problem un-prompted, is possibly trying to head off a "class action"!!

Pretty sure the boat is on the bank. (Hence the warnings about scope for ballasting problems.)

And in a similar vein, I've sneaky suspicion Sir Christopher Wren didn't literally build St Paul's Cathedral using his own bare hands. Happy to be proved wrong though!!

Its a curious thing, on the many (over the decades) I've had occasion to complain to a company about <whatever>, they nearly always make an effort to tell me I'm the only one with this problem. And once, on the gas engineer forum, there were several of us making the same complaint to a boiler manu and all of us were told we were the only one with the problem. This was even happening with the Postmasters scandal. All of them were told by the Horizon helpline when they first asked for help that no-one else was having any difficulty. Apols for swerving off topic....

Did you actually read the OP?

Very decent of him to answer on a Sunday, IMO. Carefully crafted wording to avoid accidentally accepting liability though!

Who's a clever boy then? Well done, pat yourself on the back. Thing is, once a thread reaches a certain length people stop reading back through the whole thread before making a helpful comment in case someone said the same thing earlier in the thread. This usually starts happening at about one page or 25 posts. This thread is up to 17 pages now, or 400+ posts!

A search using 'what'? If you were googling, its hardly CRTs fault that google isn't returning the page you want. The CRT stoppages section is here: https://canalrivertrust.org.uk/notices?page=1&tab=0 Where you select your waterway, dates and other filters to get a sensible result.

Translation: "I dunno how to use ChatGPT" 🤣

ChatGPT said otherwise! Baseplate and sides up to say, 600mm

I think the theory is the fisheyes are forming over microscopic corrosion pits filled with rust which the surface prep could not erase. Rust soaks up Vactan like no tomorrow so I'd expect rust in tiny pits to suck it up, making a fisheye.

I'm inclined to agree. When I step off my stern with the centreline in anything more than a light offshore breeze, it is near impossible to pull the bow in by the centreline using brute force. I appreciate I only have half the mechanical advantage but I doubt the average BT would overcome the force of a steady 30 mph wind.

I worked out that the 40ft boat mentioned earlier will have had 1.9 tonnes of steel added. At a total guess, there was probably about the same amount of ballast removed from that boat. 1.9 tonnes of engineering bricks is a very big pile which should be nearby.

Which mainly illustrates that overplating is not necessarily a physical need, but it only done to get insurance. Somewhat perverse given the chances are that the boat was alrady floating fine, and the gap between the hull proper and the overplating is possibly flooding and corroding out of sight.

And I'd assert in most cases of over-plating, it would have stayed afloat for another 10 or 20 years without the over-plating being done...
