Could this type of boat be converted to a junk rig ?

    I draw a rapid draft with a theorical weight 5300 kg and a 70 sqm sail area...

    She doesn't look fantastic but it's just a study case...

    Yes, displacement and draught are wrong.

    I am going to investigate...

    Sorry, the meanings were so familiar to me that I forgot to translate them.

    GTE is for "grand tirant d'eau":  deap draught.

    I suppose that there are two versions one with a fixed deap draught and the other with a shallower draught and a center board or a lifting keel.

    Hi Renaud

    Could you let us know the basic numbers of your boat, length, beam, displacement and ballast weight (and type)?

    Arne

    PS: Is it a centre board trunk I spot on the profile drawing?

    Arne, I found the information on one of Eric's links:

    Longueur de coque (m) 11.8  - LOA

    Largeur de coque (m) 3.54  -  Beam

    Longueur de flottaison (m) 10.13    - DWL

    Type d'appendice Quillard GTE    - Keelboat  (GTE= ?)

    Matériau Bois   - wood

    Tirant d'eau (m) 1.8   - Draught

    Voilure (m²) 88 sq m   - Sail area 

    Light displacement (kg) 5300

    I see that she is actually rigged as a gaff cutter, not a two-masted lugger, so it would make sense to try and put the mainmast in the current mast's position, wouldn't it?

    I had the opportunity to buy a 12 meters plywood boat, built in 1996 (she is very cheap). She has traditional shape (initially with balanced lugs).

    What's she inspire to you ? She can be converted to junk rig ? The result will be elegant ?


    Thanks and sorry for my poor english...

    Renaud



    I think she would make a most elegant junk-rigged boat.  She has the same air as Peregrine.

    This beautiful JR is a Hasler/McLeod JR ?

    Renaud


    Grace Ellen, as this boat is called has standard Hasler McLeod sails in profile, with conventional camber (as in bermudian, gaff or lugsails), and uses hinged battens.  The boat sails like a witch (I've been for a sail) but the battens do not have positive batten stagger and the sails require luff downhauls to set properly.  Gary, her skipper is happy to pay that price.  I prefer less performance and what Hasler called automatic handling, you let the halyard go, if the wind is forward of the beam, and the sail neatly stacks itself with just the right amount of positive batten stagger.  I was eventually able to get my Arne-style cambered sail to do that, using fixed luff parrels (although Arne gets away without them, I couldn't, perhaps because of my shorter yard and/or forward-raked mast).  My new, flat sail is also a modified Hasler McLeod type (three fanned panels instead of two and a shorter yard).  It sails quite well to windward, even in light winds, provided the sea is flat, but is a lot slower to accelerate out of tacks.  For inshore sailing, some form of camber is probably best, but for open water cruising it does not matter so much.  I try not to sail to windward offshore, picking my weather on long coastal passages, or changing my course if further offshore. I motorsail if I am trying to make a landfall with an adverse wind. 


    I like the look of this boat you are considering, though the aft rake of the masts is not really suitable for junk rig.  Is it possible to step them vertically?  Good luck!

    Bonsoir

    I suppose that the boat is that one:

    http://www.bateaubois.com/fora/viewtopic.php?t=3263

    The centerboard can be seen on a view.

    The general description may be found on:

    http://www.voilesetvoiliers.com/fiche-technique/ship_id=23116/

    or

    http://www.hisse-et-oh.com/bateaux/avel-abenn

    but be causious because, for example, the centerboard is not documented.

    As the architect was working in the boatyard they may have done some local improvements.

    Ah, I see now that the motor is offset to starboard, because of the centreboard. That means that the mast cannot come further back - unless it is offset as well, which is quite possible.

    Hi Arne,

    The boat is not mine yet.

    The kind saler know little bit about his boat. He bought her many years ago but never sail her.

    So I don't know all dimensions.
    LOA : 12m    LWL : ?
    Beam : 3.45m    Displacement, weight : ?

    I am trying to contact the architect of the boat to know more about her.

    So I don't want to waste your time !

    Now I will study documentations on JRA website and books.

    Yes, there is a centerboard.

    Regards
