A period that I still look back upon fondly. It could be argued that I spent most of 1975 to 1987 sailing offshore on a cav 32.
You have any issue in a following sea with her little backside? There is some foreign designer / builder that lives down south island, that says some less than savoury things about the following sea capabilities of Cav 32's & Contessa 32's .... but I think he also doesn't believe in drogues, so maybe a crackpot

Calling BP...think he went offshore in one years ago
Edit: I have magic powers! -
Another question: Why do you think someone recommended in this thread that the athwartships structural floor beams that will span my bilge and tie everything in post removal of the glassed in integral water tank -- why should these be solid wood over plywood? I am going to glue and glass them in, so I am interest why they should be solid would. A boat-builder friend, albeit a DIY boatbuilder rather than a commercial one, reckons plywood will be fine and actually stronger, and it is going to all glassed in, so no need for solid wood.
It is a GRP constructed boat from the the early 1970's btw
Thoughts Crew team?
ps. I went with Meranti 18mm for the bulkheads, and Okume Joubert 9mm for the rest of the interior rebuild.
Cheers

I don't feel so bad about my old fashioned transom hung rudder on pintles and gudgeons.

Very interesting article, thank you sir.
The last paragraph:
"AllDone’s story highlights the unseen but ongoing role of human workers on the frontiers of automation, and it demonstrates why it’s too soon to forecast a future of full automation or a world without work. The interdependence between generously compensated software engineers in San Francisco and low-cost contractors in the Philippines suggests that advances in software automation still rely not only on human labor, but also on global inequalities.
While this may be true - for this particular company - as at April 2024.... that will not be true in April 2034. AI will definitely be advanced enough by then to work better than any 'human algorithm'.
I also have a moral repugnance against hiring workers in 3rd world countries denying home country workers a job because you can pay the offshore worker $2 per hour -- but probably not something to explore in this thread as I could see it going political very quickly, and political threads are no longer permitted on this forum and fair enough.-

AI is real though - your grandkids kids are going to live in an unrecognisable world in short order -- I am talking 15 to 20 years from now or less.

The same question asked a couple different ways:
________You
A yes or no answer only please. Is there a chance that all current "sit at desk" jobs could be replaced by AI in the future?
ChatGPT
Yes.
You
A yes or no answer only please. If it is true that there is a chance that all current "sit at desk" jobs could be replaced by AI in the future, then is there also a chance that physical and trade labor jobs could also disappear as well because the rest of the population do not have jobs and therefore do not have the money to pay for those trade services?
ChatGPT
Yes

I put this question to the AI system called ChapGPT . Make of it what you will....
--------You
A yes or no answer only please. Is there a chance that AI could cause the world's economies to collapse in on themselves as there is no longer enough humans working jobs to pay for goods and services?
ChatGPT
Yes.

Is it possible to drive north of the Brynderwyns?
Or is it quicker to go by boat to a coastal harbour, like the pre-colonial trading days?
(PS, semi serious question, I never know if the Brynderwyns / SH1 are closed for maintenance or not)
Brywnderwyns are currently open for Easter.... after that you are back to going the diverted route/s to Whangarei I guess

Any 64gb Android will do the job, but I have found this couple give a very good run down of pros and cons, and cost v effectiveness...
https://sailingkerguelen.com/en/best-gps-tablet-navigation-android-apple/
Edit: If you decided to go IOS over Android, pay careful attention to the difference between Apple wifi v cellular. You always want the cellular option if you are prepared to pay the Apple premium, because they have GPS, and Wifi only models don't. Android models (as far as I am aware) all have built in GPS whether it is cellular capable or not.
BTW, I use the term GPS in it's broadest sense - there are many satellite providers these days, but I just band them together under GPS in my brain to save having to remember names like Galileo, Beidou or Glonass. -
That's three options now - who knew! thanks very much lads.

Thanks K4!

A closer look at those outfits, shows they sell the gudgeons -- I am after the little spacer / bushing
-
Anyone got any idea who could make me a bespoke set of these ? A google search shows off the shelf ones sold at various marine outlets, but surely there is an outfit that can make the exact OD and ID that you need for particular rudder's gudgeon's?
Cheers in advance for any info provided. -
Rather than stupid xxx xxxx the country can't afford -- put a couple hundred $million into building a dozen of these machine and just go to town on this caulerpa. It sure beats trying to enforce stupid anchoring bans which no ones takes notice of anyway https://www.rnz.co.nz/news/ldr/508904/70-boats-illegally-anchored-in-bay-of-islands-caulerpa-ban-area-over-summer

Sometimes, what we used to think was perfectly normal behaviour, or infact behaviour to be proud of and celebrated, sometimes that turns out to be really feckin bad for you. But it takes time to understand that what you are doing is stupid.
Before rugby league cracked down on the kamikaze tackles and high shots, a little Bulldogs player was making his name as the second coming of David “Cement” Gillespie.
Kyle “Killer” White was built like a halfback, but no one dared tell him to play like one. It didn’t matter what number was on his back, he would hunt down some of the game’s most feared forwards.
In just his 11th top-grade game for the Bulldogs in 1990 at Belmore, he sprinted out of the defensive line, launched through the air and crashed into Raiders legend Dean Lance, who was the cornerstone of a star-studded team which included names like Meninga, Stuart, Lazarus and Belcher.
If that tackle had happened today, White would be lucky to play again this season. Back then, it meant instant ascension to cult hero status.
“That’s one of the biggest hits I’ve ever seen on a football paddock,” the commentator at the time says. “Have a look at the truck that just hit him.”
The truck was White.
For years afterwards – with Western Suburbs, Illawarra and later Widnes and Workington Town in England – White would play with the same fearlessness in a top-grade career which spanned a decade.
Now, nine months after his death at just 53, it can be revealed White died with the degenerative brain disease chronic traumatic encephalopathy (CTE), which is linked to repeated head trauma.
I played rugby league, and it is the toughest game on the planet as far as the toll it takes on your body, and your head area is one of the main areas of the body that is vulnerable. I got knocked out a few times quite severely, and had to give the game away due to lower back and hamstring injuries at the young age of 20 -- looking back I now count myself lucky as I had that kamikaze attitude on field where I took a masochistic joy in smashing 18 stone players in tackles.
I am still not sure though that helmets on boats are good ideas when I think the underlying issue is the way the rigs are being set up on some boats.
Anyway, good to have a civil discourse on this obviously important part of sailing.Cheers

It reduces the risk of damage, and in some cases that may be the difference between a hell of a fright and momentarily stunned, between a short period of unconsciousness and being brain dead. As I said above, once the forces get ginormous, all bets are off.
Nothing provides absolute protection. This is risk management, not risk removal.
Again, not arguing for compulsory helmets, just trying to address unsubstantiated categorical claims.
No offence, but that is not correct. Concussion is the brain rattling inside the head, and that effect does not reduce because you have a helmet on, in fact some of the new hypothesis is that helmets may add to the reverberation of the brain inside the skull as the helmet does not allow the "natural give" of the neck muscles or even worse if the helmet is not a proper fit. However, hit hard enough helmet or no helmet, you will be knocked of your feet and or knocked out cold.

Getting whacked by boom with a helmet on is not going to do anything for you other than lessening the chance of bleeding. The force of an errant swinging boom will still knock you out and / or overboard. It is the same false sense of security that some people mistakenly think that headgear in boxing and rugby provides - it doesn't.
-
Shouldn't Cat 1 - 3 be evolved then to have a look at minimising the risk of Platino like accidents that seem to keep on happening? I mean, what is more important, to make sure you have three buckets, or to have a set up which minimizes to near zero your chance of getting killed by your rigging?

Bed-it is one product that lives up to the hype.
The only thing you have to be careful about is using solvents around it...if you have penchant for walking round your deck with a turps laden rag cleaning this 'n that, just be careful around fittings that have Bed-it. -

tauranga harbour is pretty shallow everywhere. Consider actual draft. A bilge keeler would suit there really well. Jon has said it first - survey. you will need one for insurance anyway, and you will need insurance for a marina berth or a mooring.
For a cheap as chips option, Raven 26. Lots of other choices though.100% Raven 26. Cheap, Safe, good headroom, an ideal learner keeler

Cav 32 modifications for ocean sailing
in TechTalk
Posted
Found it: Eric from Nordkyn Design on the Contessa 32 and the weakness of that pinched stern in following seas:
Heavy weather dynamics: the behaviour of yachts in following seas | Nordkyn Design
These are his opinions, not mime.
The Cav gets a mention:
Hindsight is always a wonderful thing of course, but – assuming that a Contessa 32 can point acceptably in high winds and heavy seas, a very open question – had she turned it around and sailed upwind, she might have come out better off because designs like this one just won’t run in heavy seas.
Another one is the Cavalier 32, with pinched stern lines, but a fin keel this time. They become completely unsteerable in following seas and broach and I know of one that was also dismasted on the same passage while trying to run and eventually made Hobart under jury rig.
