Proper marine plywood is extremely resistant to delamination and in the time I remember the wood was even boilproof for several hours . This is how aircraft were once constructed and the resin glues are very strong .
Will an impregnated plywood hull last as long as a fibreglass hull? Does impregnated plywood suffer osmosis? Is the ply marine grade or hold some special characteristic? What happens if you get hull damage and reveal the ply cross section.. - Will it become water sodden and delaminate? How would you repair damage? Would you just use glass and epoxy? Is the use of ply panels a compromise with respect to design cases where you would normally like to have compound curves? Is a boat built at your yard in July as strong as a boat built in December with respect to resin cure?
Dear Mr Dutton Thanks for reaching out! We are currently in the process of collecting detailed answers to your questions, together with our engineering team. We’ll get back to you in the shortest delay. Thank you for your patience. Fair winds, The RM Yachts team
@@PaulAnthonyDuttonUk Will an impregnated plywood hull last as long as a fibreglass hull? Yes. Impregnated plywood is as durable as fiberglass. Does impregnated plywood suffer osmosis? No. Osmosis only concerns polyester resins. You can’t have osmosis on impregnated plywood. Is the ply marine grade or hold some special characteristic? We only use marine-grade plywood. What happens if you get hull damage and reveal the ply cross section.. - Will it become water sodden and delaminate? There’s no specific risk of delamination. Wood deterioration only occurs after a (very) long exposure to water. How would you repair damage? Would you just use glass and epoxy? Yes, just fiberglass and epoxy. And add another small piece of impregnated plywood if needed. Is the use of ply panels a compromise with respect to design cases where you would normally like to have compound curves? The use of ply panels is not a compromise. It’s ruled by design guidelines: hard chine, elevated forefoot, etc. Is a boat built at your yard in July as strong as a boat built in December with respect to resin cure? There is no difference. We work in a temperature & hygrometry-controlled environment, so that the resin mechanical characteristics are maintained at their best level. Ask our team any question you have in mind : www.rm-yachts.com/en/contact-en-info/
What is the hull gets damaged by sharp objects? Water will be absorbed by the wood, it will expand and swell. The structure will be deformed. So what the experience with scratches and damage to the hull?
Great method of construction but not new or uncommon. I have been building yachts with plywood and epoxy since the early 1990's. These boats are still as structurally sound as the day they were built.

Always loved these yachts

@@rmyachts3298 Have seen the reply so many thanks. I have some other questions about keel choice but will use the email you provided.
Composite hemp sheets and resin are the future I believe.
We are trying to advance the hemp growing and usage here in America if there’s anyway to help please contact us
Bonjour. Peut-on commander a votre chantier naval un bateau sur mesure dans la classe 5.80 globe transat pour la course en solitaire autour du monde ?
I am leaning more and more towards RM. Question: are the plywood linings in the deck also imbedded with resin, or are they 'just' plywood?
I guess by the end everything is embedded, in this phase only the joints
What is the hull gets damaged by sharp objects? Water will be absorbed by the wood, it will expand and swell. The structure will be deformed. So what the experience with scratches and damage to the hull?
I believe the hull is wrapped in a few layers of Kevlar.
Very nice results. Would love to sail on that boat.
Relatively heavy
I wonder what kind of model this yacht is, what brand and how much fit 😏🤠🤳

Vous avez l'air fatigues les gars :) (mais aussi superbe bateaux! )

Article from a sail magazine.
Beau voilier mais esqu'ils ont une bonne longeviter? 40/50 ans de vie...
ragtime is a plywood epoxy boat and its old as fuck, check it out.
such a shame you have not discovered Plasticell foam boards .ok stay in the past I prefer to move on into the future .
Performant legé mais fragile. Oublie le nord
A comparer avec la résine, pas avec l'alu
