Cold Moulded Boats Illustrated Guide

It's a 38 feet one off project by Nestor Volker, an argentinian engineer that used to work with German Frers.
It was built in 92-93, with mahogany laminate fiber glass vennered by a well renowed wood shipyard in the very south of Brazil. The ribs (infrastructure) are all laminated with carbon fiber. The builder used, at that time, Cascofen as glue (what you can say about?), i discovered this recently.
I bought the boat 2 years ago with very little use (300 hours motor!) and she never been in salt water untill last summer (south hemisphere). It has a shallow draft with a short keel and centerboard. It's provided with a pilot house as you can see in the pictures attached.
Cheers!

Howdy Carlo!

WOW! Your boat looks very nice!

I like what I see. Show us more! Post some more photos.

I like the inside steering position (with joy stick control). I like the curved wood inside. Looks very nicely finished.

And the exterior looks like a nice modern design too.

Post more photos of her, and show us her charms.

Beautiful looking. What part of the world are you sailing now?

Cascofen is being mentioned i.a. here:

Renovering/förbättring av Ryds Hajen HT -79 - Page 25 - Scandinavian Trolling

I have never seen it before. What is it like? What chemistry is it?

The only thing I know os that Cascofen is a phenolic glue used nowadays in plywoods and that before epoxy days was used in large scale for wooden boats, as it says in this article

And here is a vídeo on a passage Back to Porto Alegre (Brasil) we made in february.

Show Your Cold Moulded Boat Sailing!

Now that the summer sailing season has started in North America, I think it is time for this thread to show some Cold Moulded Boats (CMB) in the act of sailing!

Please post a photo of YOUR boat sailing, or of your favorite Cold Moulded Boat model sailing.

Whether it is your own Pride and Joy, or your Dream Boat, let's show the CF members what makes the Cold Moulded Boats so special.

Perhaps you have a photo of your Cold Moulded Boat Boat gunk holing in the Chesapeake. Or a photo showing your boat being built. Or showing your boat's special features. Or a photo showing some of the wood interior. Show us.

Let's put in some more photos to illustrate the Cold Moulded Boat world here in this thread.

IF you don't have a photo of your own boat sailing, then do a Google image search and find a sistership. Or post a photo of another Cold Moulded Boat you admire.

And, if you have been doing some cruising on your Cold Moulded Boat, take a photo from your blog or own site and share it here, with some comments about what you liked about your boat on your cruise. Tell others about YOUR boat or your model. Post a link to your blog if you have one.

Share your love of Cold Moulded Boats.

Let's see some sails! Let's see some boats!

Steady, it occurs to me that perhaps you have not had a look at the photos posted in my profile. Showing Insatiable II sailing, at anchor and interior shots. Don't kknow how to repost them in this thread.

And re the talk of keels being ripped out of the hull... In our design, there is a massive "H" beam of Aussie hardwood that runs from forward of the mast step to aft of the engine mounts. It is tied into the floors and ring frames, and the keel is hung from it, not from the shell of the hull. Extremely strong, stiffens the whole hull and removes any thought to the keel departing whilst the bolts are intact.

When we first bought the boat, our first timber boat ever, we sorta thought of her as fragile. Fourteen years and nearly 60,000 miles later, that worry has vanished! Besides the stresses of sailing lots of miles, she has survived being T-boned at anchor by a ~40 foot old race boat. The offending bit was a stainless anchor roller assembly which consisted of two 1/4 inch thick by 3 inch high s/s plates. The boat was doing around 3-4 knots and hit us broadside, bounced off and did it again, just to be sure I guess. We were below and thought the world was ending! Total damage was two 3X 1/4 inch holes punched through the thin f/g skin and about 3/4 of the way through the cedar strakes... in two spots on the hull. The interior f/g skin was undisturbed, and there was no delamination of the outer skin around the punctures. Astonishing, really. The repair was simple enough, chiseling out around the damage, making a fairing block, epoxying it in place, glassing over, fairing and painting. Accomplished in the water by the perpetrator's younger brother who was an apprentice shipwright. The result is equally strong as the original and is undetectable inside or out. IMO, easier and better than a similar repair in a FRP hull.

We're pretty happy with our cedar boat!

That's my thought too! I'm making little repairs in wood/epoxy, and mahogany is so easy to work cause don't produce many splinters.

BTW, thanks SteadyHand to appreciate Gulliver's layout

[TeddyDiver]

My build some time back. Now the deck and superstructure are done and laminated.

[rumiko dan]

Do RM yatchts fit into this category?
Hull in epoxy impregnated marine ply

Exclusive concept - RM Yachts


Also, one other question, alluded to earlier by another poster: How fragile would this type of hull be to a collision of whatever type, and how would one do a repair?


Thanks to Steady, as always, and all the other great posters!

I would be too!

Jim, thanks for participating in this thread, and in CF in general. You and Ann add so much to the experience level of the discussions, with admirable time and miles and wisdom shown in your life cruising. .

Your example of a Cold Moulded Boat (CMB) going so far and cruising in the South Pacific is outstanding and and impressive, truly exemplary!

I think this thread would benefit from seeing photos of your boat. I know there must be a way to copy the links from your photos (in your CF albums) and then paste that link into this thread. I have not done that myself, but as I recall, that is how it works. I will look into it when I can, but unfortunately, won't be able to do that for a while. Perhaps Ann could ask one of the other moderators who does know and that will help. Photos do help others see things, and add to the enjoyment of this forum.

With Respect and Regards!
Steady

Thanks for posting those photos. Interesting.

Please post a line drawing of your boat design (profile).

I would like to see what it will look like when you are finished.

[Lance Reynolds]

Thanks for this thread .
Here is my West System Epoxy Glass Encapsulated Strip Plank Western Red Cedar "Whitehaven" 11.7m.
This method creates integrated strength by allowing compound curves in both the deck structure and hulls , with this form you can minimize the interior supports equalling a strong and light sailing Cat.
Also the stream lined deck and cabin top give minimal wind resistance even producing a foil for lift to the whole boat she is nice to sail and very responsive to pressure increases .
Two photos are from a recent refit .
This comfy cruising Catamaran is currently on the market , see CF Classifieds.

[Steadman Uhlich]

TO: Lance Reynolds

That is a nice looking cat. I do like the curves (lines) and it does look sleek.
Thanks for adding it to the mix of boats in this thread.

[longjonsilver]

Does anybody know of any resources specifically to surveying a cold molded hull? i would appreciate all links
thanks

My Disclaimers and A Few Requests

I have no financial or other connection to this boat, the owner, or the seller.
I have not seen this boat in person, nor have I sailed on it. But I would like to sail on one.
As with any boat, it is a good idea to research the design to learn about how they sail, common problems and owner opinions.
As with any boat, it is smart to have a qualified yacht surveyor perform a survey of the boat to assess its condition.
I am posting this to help others find boats. This one caught my eye, and I hope this thread helps others find a good fit for them.
I hope this thread proves helpful to CF Members. If so, let me know, as it is nice to know the time spent on it has helped others.
IF you purchase this boat, let me know (a Private Message would be OK).
IF you purchase this boat, I would enjoy seeing it, or going for a sail on it, if I am ever in your area. Or, if you own a similar or sister boat send me a PM. I enjoy sailing on a wide variety of boats and would like to get some time on many designs, including this one.

Good luck on your boat hunt!
