Wooden boats rot from freshwater collecting either in the bilge from rainfall or around the deck and cabin.
I had a plywood Hartley TS that would be around 50 yo. But that wasnt epoxy coated.
I wouldn't feel nervous about a properly designed and constructed timber boat.

RM Yachts are interesting sail boats (there you go Loosechange :).Epoxy impregnated ply construction hulls with epoxy sheathing. Light, stiff and strong. I like the concept, ply allows for big gains in stiffness for performance boats it seems.
Construction vid:
Review here are of one model:
Yes, I have liked the RM boats and French boats in general for a long time now, I find nothing wrong with ply or timber boats and in fact possibly prefer it to a lot of other material choices. But like all things it has to be designed for the chosen material and built accordingly.
It is a bit erroneous to call it epoxy impregnated ply construction because when using ply, saturation can only be achieved to the first glue line of the first veneer and bearing in mind that some first veneers can be as thin as 1.5mm that is not a lot of saturation.

Yeah I wondered about how much saturation is actually achieved. I guess that's a pretty effective 1.5 mm though. And to put things in perspective, any cored fiberglass boat is susceptible to core saturation If the skin layer is compromised, a 1.5 mm layer under the skin is at least another small line of defense for minor damage. As a boat maker using ply, a ply product laid up with epoxy glue lines and each layer of ply epoxy saturated, would be the ultimate material! I'm sure they've experimented with this and it's either been too expensive or too stiff for forming or both, what do you think?

Hi Ramona
I looking at the designers website I think the hull is ply as well
I called the owner/builder last night and he seemed like a genuine knowledgeable bloke
He said the hull and deck has glass matting over the ply as well
Probably double diagonal ply with epoxy and 'glass sheaving. If there ever was a hole the water would not run far before it came to an epoxy barrier. Lot harder outer skin than a fibreglass boat and actually waterproof. I would always prefer to see an accurate description of the hull description in ads for composite hulls.
Heres a bullet proof cruiser, for a buyer !!! https://yachthub.com/list/yachts-for-sale/used/sail-monohulls/island-packet-35/223737

Wow that definitely looks like a great deal. Some amazing buys around. As a boat owner this a bit of a worry mind you, but luckily I didn't buy a boat to make money (mad but not certifiable yet).
Amazingly I met a guy who had just bought a Chieftan 38 for $6K. (NZ built Bruce Farr design) the boat looked in great condition and had a new Volvo 40hp installed with zero hours. He had his Jarkan 34 on the hard and the owner of the Chieftan was in the next spot. The owner said he was over sailing and wanted to sell, so he bought the Chieftan for %6k and sold his Jarkan for considerably more within weeks.
I'm still stewing as I hauled out in the same yard and it could have been in a my new 38 footer if he hadn't got in first!

I'm fairly sure the Chieftain I know of isn't a Farr design and doesn't appear on his list of designs?
My apologies. I thought it was a modified Farr, but the design is attributed to the Cooke Brothers yacht builders.
Good pick up Chris

How about the first 16 odd Timber Top Hats built by Mouldcraft in Melbourne in 1965-6.
As far as I know [and please correct me if you know differently] only one has sunk [at Williamstown] being destroyed by wood rot.
A couple have been wrecked, but as far as I know the other 13 odd are still going after 53 years.

anything built in Melbourne is probably still floating ! no seriously there is another 13 ......

I would much prefer a 5 year old motor with 1000 hours on it then a 10 year old with 100. Like most things on boats they last longer being used.
You are right on the mark there. Use it or lose it.

.?????? Mates, mechanically where are you coming from ??!
A lightly used engine will glaze its bores, I'm ok with that. But if you don't turn it on how can it be less ? Good ?
We are talking diesels not petrol were engine oil breaks down from the ring bypass ( unless synthetic oil is used )

that is a missleading statement. If the engine is in good nick and there has been and there is OIL in it and no rust eats it away a 10 year old engine with 100 hours on it is still a brand new engine. Metal does not go bad like food in your refrigerator.

Nup. That 10 year old engine with 100 hours is likely to have suffered from corrosion.

yes metal does go bad . without regular oil changes an engine will be eaten away by a reaction in the oil . change the oil on time not hours use !!

Pity there aren't any inside photos, but that looks like a lot of boat for $29k!
