    Default Build & Rebuild Log Marblehead Esterel LE

    Hi,
    Here I will try to best show the build and continuous rebuild of my Marblehead Esterel LE based on Claudio's design.
    The design was originally called Esterel Diamond (due to it's shape) but renamed afterwards, since somebody else used the "diamond" name for his design.
    LE stands for Lardis Edition, since I did not build the boat, but my very good friend (and benefactor) Christos Lardis, got tired of my constant nagging and various proposals and said "you have it and let us see how can you race it"
    I'm not sure which exact version of Claudio's design did Christos use and to tell you the truth I'm currently looking for details about keel-bulb-rudder since I would like to 3D print those parts.
    So let me begin with whatever pictures we managed to find from the original build.

    After coating it with glass-epoxy, the boat was cut from it's supports and the deck was created.

    After coating and sanding, it was spray painted with filler and sanded again.





    And from the finished model a mold was created. Christos created a port-starboard mold instead of body-deck to get an obvious center line and join the two parts easier.



    Then he found out it was quite a task to internally reinforce the joints, through the deck openings, but he finally made it.
    The keel was made by pressing foam boards around pre-shaped plywood so the carbon would take it's shape and stick with almost no bubbles.



    The first boat was made of a very lightweight glass-epoxy combination and was quite see-through.
    Since it was a test build, it was set only for swing rig sails.

    In the following video you may witness that boat's maiden voyage. The high dock, trees and parked cruiser always made it very hard to find the wind direction and that was one of the reasons we stopped racing at the specific point.
    Another was that, now that our "M" fleet has grown, we need much more space.

    Following the success of the first build, a carbon version was created using the same mold.





    And a third one:

    During his search for the best material-weight-toughness ratio, Christos built a Kevlar version that was (hypothetically) a bit heavier than the rest but potentially unsinkable. Later on it proved to be lighter than expected and that beauty, was destined to end up with me.





    Here is her maiden voyage.

    The boat had a small problem with the keel-box and was taking in lots of water. I strap some, fishing net string, around it before using a light glass cloth and epoxy, to make it as strong as the rest of the boat.
    Then had to make her ready for classic (shroudless) rigs.





    I also had to cover my fear of getting any water on the electronics. You see, 99,9% of our sailing is done in salt water which is disastrous for batteries and receivers. So I always like to have those in a sealed container to rule out any possibility of contact.
    Also I like to be able to quickly turn everything on/off with no switch and change batteries between races.
    Usually that means adding much weight but I found a solution that covers me for now.
    The top part is a urine sample cup, cut to about a centimeter from the bottom of it's cap. The cap is sanded to the very point where the screw begins in order to save weight and height over the deck.
    The bottom part is from a bottle containing rubbing alcohol. It was heated to shrink on the cup and then I added glue to seal any holes.
    The whole part was then glued, with silicone, on a piece of glass-epoxy with which I covered the left opening.

    Abi,
    very glad to hear about the finalization of the Class M Esterel.
    From the pictures I would says that the model's design used is the Esterel "Ruby" ND-RB. ND stay for "Narrow Deck" and RB for "Reverse Bow".
    Pity that from the video is not easy to appreciate the effect of the Reverse Bow versus Nose Down.
    Any appreciation about the speed is welcome.
    True that the name 'Diamond' was abandoned because already used and replaced by the 'Ruby' with some design changes. Both PDF data are still available on this forum.
    Thanks a lot !

    Cheers

    Oh! It is very simple Claudio....i did too many changes, with no testing in between. I also added much weight at various points without checking the balance. It was a disaster waiting to happen and I am to blame 100%
    Also (after some research) it seems I was having problems with my transmitter or the receiver so I will have to check those too.
    Now I'm waiting for Christos to come back from his summer vacations to continue the Rebuild.

    Thanks again for a fantastic design,
    I'll be back soon with more pictures.
    Abi
