    Mono Heel fatigue vs Catamaran SLAP, oh to dream canter keel cruiser

    in MarineTalk

    Posted

    Wheels im not sure I get you here. Are you saying the boat actually lifts to windward and the bow is pointing lower than it actually is heading?

    I think it's the opposite. The bow pointing up but the boat sliping sideways to leward. Leeway. Course over ground is lower than the heading.

    Or is that what you are meaning?

     

    All the cats we cruised with offshore were pretty comfortable by all accounts but slow. We were rolling alot downwind (which is all we ever did..) but going generally much faster. Any boat is bloody uncomfortable going upwind!

     

    All Mono Hulls, Canting Keel included, heel unless going down wind. That is why the Hull has such a shape as it does. It acts as a wing in the water, along with the Keel and Rudder, to give the Boat "lift". If you have ever watched a Sailboat coming toward you, you will notice the Boat actually sails slightly side ways. Apart from down wind, no Sailing Mono hull points directly in the direction it is headed. It is in fact being "lifted"in the direction it is headed and the Bow will always point slightly down wind.

    Has to be one of the most successful boats ever.

    Won the volvo race, Sydney Hobart, transatlantic, Caribbean 600, and now the fastnet.

    Thats all i can remember but there could be more.

    Really interesting cockpit/cabin setup. I would love to see how that cockpit area works under the cabin with sheet leads ect. I guess the idea is to reduce windage and maximise shelter. These guys are pretty sharp with concepts and love pushing boundaries.

    If it holds together then this boat will most likey win the vendee.

    I don't think it sounds like the rigging screw failing.  On a lot of those Euro production boats the lower end of the rigging is connected to a rod that connects to the hull behind the saloon seats.  "A steel rod connecting a metal plate at the base of the mast to the boat's superstructure snapped"  sounds to me as though they had a failure in that rod, or more likely one of the ends.  This would be backed up by their fix of running a line under the hull.  If a rigging screw had failed their fix would have used the existing chainplate/rod.

     

    This would also explain why a rig inspection would not have picked up an issue with the connecting rod - it would be a reasonable expectation that this part of the rig was fine, and you most likely couldn't inspect it unless you pulled the entire assembly out.

     Yeah for sure it doesn't sound like a rigging screw and your suggestion makes more sense than the mast post. Scary stuff. That same thing happened to a local race boat a few years back. it was messy....

    Sounds more like a mastbase/compression post issue than an actual rigging failure?

    Quite common in these older production boats with deck stepped masts. Either the posts fail or the deck delaminates when the wood core rots.

    Usually a rigging check will probably not pick this up as its a structural boat issue and regardless rigging checks are pretty limited to spotting anything thats actually already broken. 

     

    I would not go offshore on a boat with rigging older than 10 years even if it had a satisfactory rigging survey/check.

    On our trip from france, 5 boats we cruised with (including us) had rigging either completley fail (one dismasting) or broken strands at the swage.

    We broke 5 strands in our D1 stay between Suwarrow and Nuie and were lucky not to loose the whole lot.

    One of our friends was not that lucky and lost the rig just out of Tonga and insurance will not pay out due to the fitting that failed being over 10 years old.

    Interesting to note that in this case the stay had been replaced but not the rigging screw and it was the rigging screw that failed so no insurance....

     

    Sounds like these guys did have a well setup and maintained yacht and knew what they were doing. Glad no one was hurt but they have lost their yacht which was also their home I believe. Sad story and I hope they have some luck with a salvage or are well insured.
