Cold-Molded Hulls?
I'm considering one of these - a 26-ft not-too-young sailboat - and
I'm curious re its prospects for the long haul, incl what to look for/ at in a survey. Any surveyors around specializing in this? Any insurance issues known? I can't avoid the impression that they might be difficult to repair well after some physical damage. Any experiences, pointers, etc. will be appreciated. Thanks, all. -AS |

Thanks, all. -AS An excerpt from Good Old Boat magazine: http://www.smaalders.net/yacht_design/gobboatconst.html Wooden Boat Construction Repairs to cold-molded hull planking are carried out by laminating new wood directly in place, having beveled or stepped back the edges of the damaged area. If the damage is extensive, temporary internal framing may be required to help define the shape of the hull, and to support the new planking as it is being glued and fastened in place. If a cold-molded hull has many internal stringers and these are damaged, they must also be repaired. As with the repair of frames on a carvel planked hull, gaining access is often the most difficult task. With cold-molded hulls damaged frames and longitudinal stringers can be cut back and new wood laminated directly in place. Backbone repairs on these hulls generally have the same complications as do those on strip planked hulls. +++++++ A Google search will turn up other references. Good luck.

Cold-Molded Hulls?
Cold-molding covers a lot of ground, so it would be nice to know what
you are looking at. The two most common techniques going by that name are diagonal planked veneers and strip planked timber, but there are others. These are one off or small run construction methods and the results will vary from builder to builder but when well done the results can be lighter, stiffer, stronger and more durable than conventional glass construction. Things you need to look for depend on the construction method. As with any boat you should sound for voids and look at the bulkhead/hull joins, engine mounts and so on. Cold-molded boats are typically built using epoxy glue. The chemistry of epoxy is critical and I've seen master boat builders make bad batches. There is no easy way to tell if the glue hasn't gone off inside the laminate so you have to trust that the builder kept track of this when building. You may get a clue about the level of care that the builder took by inspecting the detailing in the normally hidden bits of the boat -- take a mirror and small, but powerful flashlight and look and feel everywhere. Also, check for rot, particularly in any parts that are pierced by fasteners and in plywood bulkheads. In a general way, repairs in wood are easier and more pleasant than repairs of glass, but YMMV. Since the boat is built with glue and wood fiber (and typically a man-made fiber covering) you can call it "composite construction" when talking with your insurance company. -- Tom. |

On a recent episode of "Shipshape Boating" John Greviskis toured the Boston Whaler factory where they proudly displayed how they construct their boats -- mostly with chopper guns. But even that is a durned sight better than the modern putty boat. I met a couple of the local chopper gun operators from a couple local boat manufacturers in Charleston. They just spray it on like paint. That CAN'T be as good as several layers of real fiberglass, whos mat gives it real strength. One of my friends commandeered my little Sea Rayder jetboat when I went to visit them on their Hatteras 56 motor yacht at Ashley Marina. The clothes dryer had clogged up its overboard vent and it was not accessible from the deck to get the deflector off it to look down its gullet. So, we stood on the bow of my jetboat and took it apart. The deflector had made a fuzz plug completely blocking the flow down into the hose. While the deflector was off, about 6" below the main deck line, I pointed out to Dan how THICK the hull of this real fiberglass boat was even way up at the deck level. I stuck my forefinger in to measure its thickness and the hull was actually THICKER than my forefinger is long!....SOLID FIBERGLASS with lots of layers you could see because this hole had been drilled out with a hole saw. I'd ride that boat in any seas....I can only imagine how thick it is at the keel! No wonder it weighs 55 tons! I watched the hauling crane struggle to lift it out of the water, creaking and groaning, at the boatyard. I felt a lot better after it was on terra firma. The straps they lifted it with looked just awful worn out. A Hatteras sport fisherman got loose from Buzzard's Roost Marina in one of our recent hurricanes, floated out of the marina and headed out to sea down river to crash up against the pilings protecting the old swing bridge. It bashed those pilings for hours in pretty big wind waves, tearing the pilings to shreds. The Hat lost its bimini top and some above deck hardware....but the hull was unscathed! THAT'S Fiberglass...

@sp12lax.superfeed.net: Wooden Boat Construction If you want that boat fixed, we got that covered in Charleston: http://www.seaislandboatworks.com/ Mark Bayne and the other shipwrights do great work, most impressive. Take a tour around the website. They're are also heavily involved in the building of the Spirit of South Carolina, our new state tall ship. It's easy to spot Mark's sport fisherman yachts in the pack of plastic burning up the diesel to get to the fishing in the morning. The lighter wooden boats are the ones passing the plastic ones....(c; The parties they throw when turning a new hull over with the help of us locals is not to be missed! It makes YOU part of the process and is great fun....a throwback to much older times.

"294578" wrote in message ... What does "Cold-Molded" mean? It refers to boats made of layers of wood bonded with glues (generally epoxies) which do not require the application of external heat. Differentiated from the old plywood construction method (for example, WWII PT boats) which used glues that set only when pressed and heated. Cold molding can be done with strips of solid wood, such as cedar, or with plywood. More often than not, it is finished with an outer layer of fiberglass cloth and resin. |
