      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Restoring F/C yacht

18 posts in this topic

Hi I'm currently restoring a centre  cockpit 11.52m double ender, its GRP coated Ferrocement I'm have no information on the design or the builder other than  I think it might be a Wilf O'Kell design built in Brisbane and was to be used on an experdtion to Antarctica by its builder owner, if anyone has any information could they let me know thanks

Delete the double post.

Unless that boat is in pretty good shape and won't cost a bundle of time & $ to restore, I'd get rid of it and get something in a better material.

BITD I was something of a fan of ferro - mostly due to the extent of it here as well as my own ignorance. Then it went through a phase of being an incredible bargain compared to other materials on the used market. Now with glass boats so cheap, even free, there is no reason to expend any effort or money on a ferro - it's totally unrecoverable, not just largely unrecoverable like other boats.

I don't think that "ferrocement" and "yacht" belong in the same sentence.

I've seen a handful where it wasn't unwarranted.

A single handful to be sure but more than a couple where I had to have it confirmed they were stone boats.

I'd have to take my socks off to count the ones I'd have before a BS boat. ;)

I knew a guy who was one of the preferred shipwrights for RVYC owners and he had a very nice one - few people recognized it as a floating footpath.

Thanks for your comments. My yacht has been floating around for some years I call it the orphan, it was striped of all its valuable assets and used as a floating Carravan, however there is no sign of ageing or leaks it was built with a Kevlar skin and with a polestar coating outside and in, Joe Walsh replaced the rigging (still in progress as I write) and I upgraded the chain plate bolts from 5/16 to 1/2in from 304 to 316SS which was a chore as they were impregnated in with polyester resin and the stainless steel chaneplates had to be redriled 
The mast, I was told by Joe Walsh was "the same aluminium extrusion as the light poles used in Canberra," it has internal ribbing for strength. It's propulsion system was a 30hp Diesel motor coupled to a hydraulic pump with an hydraulic motor driven propeller fitted to the stern, that was lifted out of the water when not being motored. I'm in the process of installing a 50hp Narni and building from scratch a new hydraulic leg. I've also had teak toerales  (as there were none) and 4 new hatches installed. So as you can see I'm committed to finish this

The last file was inserted by mistake but I do follow the sale of ferro yachts to gage the build quality and value.

While my yacht was being rerigged there was another double ended fibreglass yacht along side me it was getting the deck replaced both yachts are around the same age the reason was it was it was a  balas core and it was saturated as a another example was Leaser Blair she was De Masted in Antarctica when the chaneplate bolts were ripped out of her hull again Balsa cored yacht.

Are you familiar with Brent Swain? Do you like Angelmann Sea Witch ketches?

First I've heard of a cement core hull structure. Sounds a bit heavy. Kidding aside, wtf?  Why would a stone hull even need composite skin (frg, Kevlar or whatever) at all? And no, I am not a fan. Although, I did think they looked cool sitting half-completed in Half Moon Bay when I was a kid. Never saw any of them launched. But the same could be said of the steel boats around there at the same time.

Ferro cored glass indeed. Skinning one with Kevlar or glass and "polestar" would be a guaranteed heavy, expensive waste of time.

Can you spell "peel" children?

I knew you could.

Joe is (or was) a sailor - had a Leaky Teaky like a CT 41 or one of the clones.

I was told by its previous owner that it had a Kevlar skin and I found it when I was removing the toerail plates from the deck   it's a yellow mat cloth as for why I gues as this was built to go to Antarctica he wonted it to bounce of icebergs. I've herd of stranger things like concreating over timber hulls. The US navy built concrete battleship during WW2

Fort Drum, the "concrete battleship" is a fortified island. Not a ship, never was. The Navy may have entertained fc as a building material but if they did I would guess as an alternate to steel over concerns about availability of steel.  Pykrete has also been entertained as a material for ship building. Doesn't mean it was a good idea. If you want to bounce off icebergs I'd suggest steel, the material of choice for every ice breaker I've ever heard of. Or wood, worked for the Fram.  Not dissing your project but your boat is an odd duck.

They built freighters out of ferro but never a warship that I'm aware of. Look up Powell River breakwater to see the hulks of some.

Alloy is the material of choice for antarctic sailing these days - that's what the pro's use anyway.

Ok I'll check my facts. This yacht has been floating around for since 1990 and is as structurally sound now as then, even the inside fittings are in perfect order, the only major items to be installed are the motor and rewired the yacht, I've had it rerigged 95% competed, panted the hull, Installed 4 new hatches, installed teak toe rales, removed the boom traveler (it was on a convex camber that's the shap of the decker ) and straitened it out re mounting it on a teak pedestal, a new self furler and headsail, cleaned out the holding tanks fuel and hydraulic oil tank, replaced the chainplate bolts.So just a few things to sort out and she be ready for surveye.
