An interesting side topic, Pogo have debuted a 32ft power boat using their sailboat hull construction techniques.
Hull is a 25mm vacuum infused foam core layup, same construction technique as their sailboats. Complete with chine!

32 ft long, weighs in at 1750kgs with motor and cruises at 12 knots using 1/2 litre per mile with a Penta 75HP.

That's a sturdy construction for a stinkboat for a minimal weight penalty. And that was due to Christian, the guy who owns Pogo being a very talented composites engineer.





A very similar story to the American MJM range of down-east (Maine) style motor yachts built by Bob Johnson of 'J' Yachts fame.

The letters stand for Mary Johnson's Motoryacht and MJMs suit the needs of a retirement age couple, Bob and his wife Mary, with a lifetime of yachting experience and utilising the high-tech production methods of 'J' yacht production such as foam cores and vacuum bagging.

Very light, ultra economical and very tasty. https://mjmyachts.com/

Most yachts are sturdier than any crew that gets thrown on board !!! The crew will falter before any yacht !!

They need to work on the ugly factor a bit!


Looking at a few of the newer boats these days it seems ugly is the new chic . They are probably onto a winner with that boat.

As a shipwright and surveyor based on some of the structural things I have seen I would not go past Sydney heads on a French yacht starting with "B".
If you want an Aussie built boat that will take you anywhere I would be looking at a "Jarkan"built yacht. Not too flashy but practical and well built.
Hope the speling iz okay????

Happy New Year everyone - Lighten up.


ztop it with that zpellin yoo! Happy New Year you too

Given the Australian males inate ability and mastery of DIY projects I am going to put up the home built ferro of the 70,s as the sturdiest vessel that a very any amount of money can buy.

By whatever definition you choose and whatever test used as a gauge the 70's home built ferro will be STURDIER than my French built Beneteau. No if no buts.
Now the test that I am going to put up as a Sturdiness index is to run the vessel onto a coral bommie head at full speed. By that measure the ferro vessel will carve its way at 3.5 knots into the coral and become a permanent edifice marking that spot for the next 100 years. At about 10 + knots my fin keeled Beneteau will rip the keel clean from the hull and shred itself onto the coral leaving as much pollution as the French nuclear tests on Mururoa

Plus one for yacht being more sturdy than the crew.

Also a lot of old ocean going yachts from all countries were massively overbuilt because not as much was known about material science, stresses, strains, etc. at the time. (and they had limited access to computers and the detailed numerical analysis that they facilitate).

Wouldn't a steel (or alum) yacht put the old "concrete coffins" to shame @ the bommies?

Was Moitessier wrong about steel?

The French ship of the line Redoubtable , sturdy in their eyes.
Before....


Aaand after.....
Less sturdy! Magic!

The poor French don't never seem to have much luck in times of war, poor souls. I do remember though that some of their French WWII ships were really beautiful... before they lost them all to everyone else.

I think this is the comment of the thread....

The old McDonald Douglas DC3 could've been almost half the weight it was if they new as much about aircraft construction then as they do now. The problem is with the old salts attitude towards modern materials and design. It is crusted on harder than the sea salt itself. in both the marine and aviation industries......

Sacre Bleu ! Shaggy. Form over function, form over function.
If it looks good it will go ok !but who cares it's French flair.
If you were surrounded by Germany , England and Spain ugh.
boring boring boring. The world would be pretty drab without the French. Actually poor old Redoubtable sacrificed herself to save the Flagship knocking off Nelson in the process.

Would be nothing left of either the steel or aluminium after 100 years. Only the mighty ferrocement vessel would display its proud heritage of Australian boatbuilding excellence.
Most of them are already over half a century old and still as good as the day they were built.

Now we get to understand why the French have the most vibrant mass production boatbuilding industry. All the boats they build keep sinking. Time to up your insurance policy shaggy.

Keep up there slowcoach. Shaggy showed pictures of French sailors under fire.. you said that human beings are fragile. I put the two together ergo French sailors are the toughest in the world.
Either you and Shaggy both off topic or mine the logical corollary.

I have personally seen the French deliver boats and they have been a total mess sheet ropes and cockpits total mess and Carnige. They don't seem to understand the word ship shape nor that they don't care.but they do deliver the end product to your door if requested.

You get what you pay for. Mass produced French or other boats make yachting accessible to many, myself included. I'm not too fussed as long as it gets me off my ass and out on the water.

G'day FR,
Thanks, I didn't realise Wild Eyes was an Aussie boat!
I still have a vivid memory off her setting off with a dozen 20l fuel containers lashed not very safely in the cockpit. Scary.

I thought she was a French open 40 ( until I did a google search that is)

G'day South,
I know what you mean, but I would argue that this is less to do with a nationality thing than an individual calling the shots. My boat was impeccably delivered by the French, though It's worth mentioning this was direct with a yard with no dealer network, I have no first hand knowledge of the bigger yards with brokers and dealerships.

Does anyone know how McConaghey's are doing? The split was awful to see, and I lost track of them after that.
