  1. 5200 would do a better job - Hey, are we second guessing Rapido"s development mods here while we await news on (for me) the more important 40 footer launch and sailing impressions. 55 tons of lift in the amas on the 60 is incorrect so best not debate the more complex structural beam attachment issue, might get real confusing.
  2. It's a project - But have you ever gazed at a pile of lumber, some rolls of glass and drums of resin and imagined your finished boat - this project is actually far less of a dream but still intimidating.
  3. So if the amas have 55 tons of "float" and are 300% she weighs 18 tons?!?!?! Or at 200% she displaces 27.5 tons and then again the more conservative 150% ratio porks her up to 36 tons - OMG!! Just messing with you but you kinda asked for it
  4. But what of the 40' and 50' that this thread was created to follow?
  5. Fiery Cross was never built to F40 dimensions. Merfyn Owen designed her to F40 but lack of funds dictated the stern cut short to by 5' and the fractional rig chopped to the hound making her masthead at around 50'. She competed in the 1988 OSTAR in the 35' class breaking her daggerboard en-route. Her foam core construction used Termanto structural foam - cheap but not the best. I would guess the pictures are as old as she is but the price is cheap reflecting a project to make her half decent.
  6. So multihuller stopped by my place on his way south to his NC base with the Cross 48 and joined our late summer multi gathering. I figured we had around 582' hull length along the bulkhead. Mostly rebuilt great old 'uns looking better than today's offering of new 'uns! The Cross will sit there while he takes on the Welsh Adventure - Go Steve!
  7. $150 for the design is a steal - are there any finished, successful versions out there? If not or existing builds are dogs it might be worth shelling out the cash for the details that count in a properly engineered structure
  8. Didn't John Shuttleworth do this a long time ago. Build at or below design weight (assuming the math was done on the immersed volumes) and it will perform. Cram eight adults aboard with their gear and supplies to occupy all those berths and you will have a wallowing raft.
  9. Keep posting the progress shots - hopefully you will instruct and inspire others - keep her light a d build her right!
  10. That’s Wonderful - any pictures? I know that Volantis was at least the second example as the prototype, which we took out for a daysail when we collected the ama shells, was built by Derek’s yard, Sandwich Marine. We were later told that the prototype was abandoned, presumably lost in severe weather in the Bay of Biscay after the foreword beam fairings were smashed in by wave action while the boat was being steered from inside the stern cabin with the emergency tiller after the awful hydraulic wheel steering failed. Volantis was built with thicker glass skins and the foreword be
  11. There were two press releases put out by two of the participating skippers after the race. Both accounts detailed what each of the skippers would have liked to have occurred - sound familiar?
  12. Waiting for the owner to share his experience. He has a lot on his plate right now trying to effect salvage operations.
  13. OK - but you actually want to go SAILING, right? Sorry Steve - that one was under the belt- but I couldn’t resist!
  14. Ah - waiting on some magic from an insurance assessor - Good Luck with that one. His job is to steer the insurance company to fulfill it’s obligation a minimum cost - then the risk analysis team step up and that’s when either underwriting costs increase or the option disappears for these type and age vessels.
  15. Bob and Ira SELL multihulls, they are SALESMEN, why would they know anything about DESIGNING, BUILDING or REPAIRING them? Gee Thanks for dismissing the knowledgable, well meant and FREE advise offered here as bad council - how would you even know if it was or not, do you have any idea whatsoever of the loading, engineering and construction of that beam. Thank goodness Bunyip Bluegum did share his misfortune and "out" the inevitable as these boats age - fortunately nobody was hurt. Guess What - Insurance companies are in business to make money and they are not stupid. They wou
  16. Not thinking beams that fail like that are much of a challenge to bettet.
  17. That’s Great gspot! So if we assume Shockwave can be had for a BOGO, “The Market Has Spoken”, fifty cents on the dollar price, all you need do now is firm up your access to $350k for your share and we can get the ball rolling - ‘course the logistics of the campaign will add bigly to the final tab but it’s a start!
  18. That picture is of the totally rebuilt Godbey Systems/Newport Blue/Up My Sleeve with carbon beams, accommodation wings, inboard diesel and (I think) new amas. She was sidelined with a failed main halyard in an OSTAR and flipped and was lost in a Route Du Rhum. Etienne set the new, (1992) and still standing, OSTAR 40' class record in the much lighter and as tired as she was at the time, original build. Jim Godbey built her in Milton, Mass to a Walter Greene design, around 1986 and raced her in Formula 40, privately funded. Later, in an effort to make her more competitive, he gutted the int
  19. Small enterprise for an aspiring boatbuilder, Stateside? Renovate/update the fleet - numbers make for economy.
  20. No - how ‘bout that certain 57 year old co-pilot takes her and does his OSTAR and I trade up to Shockwave and russel up some young blood for my TWOSTAR.
  21. The laminate, particularly a structural one, is far longer lasting than the cemented flanged joint. Eliminating the flange in favor of some bi-axial will not only provide a longer lasting, stronger joint for the two "halves" it will also supplement whatever filaments are in there handling the shear loading when the bi-axial is extended to the upper and lower elements. If there are any concerns that the 30 year old laminate has degraded through resin imbrittlement or cycle accumulation and showing a diminished service factor you could add some uni top and bottom. If the beams are all
  22. The "preventive maintenance" of bolting the flanges is ill advised. I helped a friend out whose Contour 34 had been "fixed" that but, and after the chainplate parted (crevice cracking) she folded (vertically) shearing both beams. The build method and the remedy is common to both designs - grind off the flanges and externally wrap the joints the same way the hull deck joint was done (properly) on the earlier (and that) build. You don't even need carbon as the demands there are low, rather a well prepped surface to bond on to (bye, bye, gelcoat) Use glass and vinylester resin
  23. Go with Zonker - learn and enjoy, you can make it stronger than new and be confident in what is under the candy coat. Finance, insurance, lack of any practical skills are sucking the life blood out and spark of the younger generation. Write the boat off for that failure - are you kidding!
