UNC/UNF

And your pronouns are?

Bi-numeral, surely? A measurement worthy of Mr Bernard St Francis Whitworth-Socket (BSF to his friends), a famed (if apocryphal) bicycle mechanic of Sheffield. Later a Design Asst. for Norton motorcycles where his flexible approach to units of measurement led to the inclusion of minor but infuriating oil leaks as a standard feature in all crankcases and a wide range of gearboxes.

Tiller. Westhaven.

I’d be keen to have a look at the installation and have a chat about that. Whereabouts are you based? And are you wheel or tiller steer? cheers

I'd just like to compliment you on your bilingual abilities, I too am reasonably fluent in imperial and own several whitworth spanners

Bottom line... It depends on the inspector... The 2014 standard which seems to be the one most look to, states that a plate is required. It must be 0.1m2, min 5mm thick and min 20mm wide. However the 2008 standard is the one that's legally required to be adhered to. I don't have that standard and don't know what it says about equipotential bonding. I just did a mates in Westhaven in November, I used the saildrive for the bond, (with a galvanic isolator), and the inspector ewof'd it...

This is the same as the Jefa DD1. I have one I am in the process of installing. It's not zero resistance with the clutch disengaged. You're still turning planetary gears which are in a sea of grease but you're not also turning the motor.

does anyone have one of these installed in their boat? I’ve currently got a B&G hydraulic ram which makes the helm feel like you’re steering an old wooden scow. Without the ram on its fingertip light which is nice. The DD15 supposedly offers no resistance when it’s in standby mode which would be nice so wanting to know if anyone has experience with them.

@IslandTime Do you know if this is still true? My eWOF is about to expire and I'm being told I'll now need to have grounding plate. Is that a new thing?

UPDATE: Nothing unusual under the rocker cover, likewise starter motor pinion and ring gear look normal. Got on the phone to the tech at Volvo and he concludes that only a seized big end or Crank Bearing could cause it to lock up with zero lash ie all other possible culprits would exhibit at least 2 or 3mm of rotation on the crank pulley. Can't see any bad reports on the interweb with Shibaura engines in fact they are considered the epitome of rugged reliability such that even Kubota use them in some products. So its into the shop it goes and we shall see, but I will update, probably in

Yes. You have a choice, sit the unit outside and duct the cool in, or sit the unit inside and duct the hot out. You can duct the return air in or out as well, depending on which way you've got it set up. Like in a car, you can have fresh cool air in, or recycle the cool air in the cabin. Easiest way to set it up on a boat is make up a spare washboard, or board to go over an open hatch, with a hole in it of the appropriate size for the duct. It also comes with a high density foam block that is easy to mount into windows (such as sliding windows, common on campervans but less so o

Does it duct the heat outside?

PS, can offer a good deal to any crew.orgers who are feeling a bit hot and bothered right now

In your jammies? The key benefit of this isn't during the day when you are swimming or general boating, it's at night when it's hot and humid and you need some sleep. Or for keeping pets cool, say on a day like today.

Call me old-fashioned, but we just jump off the back of the boat when it gets a bit warm.

Beat the heat, have a good night sleep. Get a portable aircon unit for your boat. Comes with battery and can run and be recharged off 12v / 24v (needs battery to run off 12v / 24v) Portable Aircon - Ecoflow Wave 2 with Battery | Trade Me Motors

I too have been playing with this. Lots of plugins available to do all sort of interesting stuff, like automatically putting my instruments into night mode at night

My old metallurgy tutor called it Differential Oxygenation, ie oxygen rich at the ends (Cathode) and as you say starved in the middle (Anode) all you need then is some electrolyte as present in damp wood and bingo you have an electrochemical cell !

I've just discovered the Signal K sever option in the CerboGX. I spent a lot of time playing around with it on this holiday as there was a lot of downtime due to the weather. There is an amazing amount of info available (250+ data feeds for my boat) as it has the NMEA2000 info + all the Victron info. Haven't gotten the graphs working yet but I'll have to try that next.

Having crossed to the dark side we stink pot softies came back to 7 Line Bay now just putting a precautionary 2nd reef in the mower😀

I'm sure the forecast 35kt put a dent in the numbers yesterday. That said I was surprised how quiet things were over xmas.

Lack of oxygen causes the corrison.

Mrs Aardvark advises that BOI is busy. So busy, they shifted bays after dinner last night. Similar around Whangaroa, and crowded at Cavallis yesterday such that they chose not to stop.
