    Hi-Viz mast top

    Perhaps also the places where chafe and damage from gear was more likely, and paint is easier to touch-up than varnish. As to the original question, I tend to think that it's all a bit irrelevant to my typical cruising around the South Coast and occasionally cross-Channel in reasonable weather...

    Bernie The Bolt

    In my experience the engineers would like to make the thing as easy and accessible to work on as possible, and then the project manager says there's no time and the accountant says there's no budget. Pete

    Boat advert pictures

    Some people are just bloody thick, no more or less to it than that. Pete

    Calling all NMEA experts

    Yes. The previous paragraph says that each interconnection should be its own two-conductor (plus shield) cable, which again isn't very convenient for a typical leisure device that wants to have multiple input and output pairs, plus perhaps power and some special-purpose signals, in a single...

    Calling all NMEA experts

    There can be and indeed is an official colour code - it's just that hardly anyone follows it ? Pete

    Replacing C80 raymarine MFD

    Assuming you mean replacing it with the modern Axiom equivalent, the Seatalk instruments will work via a small interface unit to STng. The radar will not. Pete

    MCB panels

    Agree. I fitted a fusebox that uses automotive blade fuses and am very happy with it. In ten years I’ve had to replace precisely one, when I forgot to turn off the power to the instrument circuit before fiddling around with the Seatalk wiring and shorted the positive and negative together. Pete

    Height of radar above waterline ?

    There will be - but modern solid-state transmitters emit so little power that it’s no longer relevant. I believe my Raymarine Quantum says the safe distance is “within the radome”. At work (where we also encounter some bigger stuff) people sometimes call these modern small leisure sets “huggable...

    Yes. The VDM sentence is what you want. Pete

    Hand-held VHF radio suggestions

    Sure. I'm not saying it will be no better, just that it won't be I think some here assumed the OP had a mast to put the antenna on top of. Pete

    Hand-held VHF radio suggestions

    On a 21-foot speedboat a fixed antenna isn’t going to be all that much higher than a handheld one. Pete

    Onboard Defibrillator

    I did the four-day first aid at work course a couple of months ago; it had a heavy emphasis on CPR and within that a lot of emphasis on AEDs, using training models with a remote that allowed the instructor to simulate different behaviour. As you say, nobody should hold back from using one...

    Hand-held VHF radio suggestions

    Another vote for Standard Horizon as a brand, though I’m not familiar with their DSC handhelds as I prefer the simpler kind for my purposes. As the main radio on board I can see the argument for DSC although I wouldn’t consider it mandatory. Pete

    Placement of Rope clutches

    Yes, of course. But lining them up with the middle of the winch as Tranona suggested would work against that. Pete

    Placement of Rope clutches

    I disagree. The rope does not meet the winch at its centre. The natural line of the rope out of the clutch should make a tangent with the left-hand (in this view) edge of the winch drum. Pete

    Why does everything have to break???

    I was just surprised that you've never even glanced at your own rudder stock, quadrant, etc. There isn't a "ram sensor". There is a rudder position sensor, which is completely separate. But you described the problem as "autpilot heading misaligned with compass", which I take to mean that the...

    3GM30 vs 3GM30F (former spares for latter?)

    I don't know for certain. But my understanding is that the only difference between the xGMxx and corresponding xGMxxF engines is the freshwater circuit and associated parts. I would assume that stuff like the oil and fuel pumps is the same. But if you want to double-check, just find the spares...

    Could an old ammo box be used as an expired Flare storage in my shed? Any thoughts?

    I was once at a back garden fireworks party where some idiot produced and without warning set off an orange smoke float. It was definitely extremely noticeable and unpleasant, and quite a lot of stuff (and people) ended up with an orange tinge. Pete

    Hurst Spit changes

    If you attend the cricket matches you can see considerable change in just one year. With the same height of tide in adjacent years I’ve seen a huge expanse well above water, and a few square feet awash surrounded by people paddling. Pete

    Why does everything have to break???

    You said the autopilot’s heading display ends up disagreeing with the compass. That’s clearly a sensor issue and not anything to do with the ram slipping on the rudder stock. Although if you have no idea how the drive unit is arranged on your boat then, as a separate issue, you should really go...
