Comparison testing of split junk by Karl Fuller video

    Hi Jan,

    The quick answer is no. Not to my knowledge.

    In my limited experience there are two or maybe three types of model boat sailors. 1. The sailboat racer who will have a boat (or a lot more) all within class rules. They tend to take the racing quite seriously so you need to be on your toes after the one minute gun! They don’t play outside class boats. 2. There is probably an equivalent motor boat racing group as I have seen the odd verrrrry fast powerboats, but I would keep well clear as I’m a sailor, not a petrol head. 3. The other group tend to build scale boats which vary from modern navy types and submarines (yes, really) down to pleasure boats with little dolls sitting having afternoon tea. Some even are Henry 8 type square riggers! As you can guess I stopped playing with dolls houses many years ago. (I’m going to be in trouble if anyone reads that comment).

    There was one SJR model, the first SJR as I built it, and it ‘sailed’ in a little circular pond with a fan blowing air out from the centre. It was used as a display at the AYRS stand at the London Boat Show for many years and as I helped on the stand for some years I got one of the moulded cat hulls and put a crude split junk profiled rig on it as a conversation starter. There were usually 4 or 5 boats in the circular trough and tied to tow each other round. The SJR did seem to pull its weight but more importantly did start a lot of conversations. I can’t find the photo I have of it at the moment, but I must remember it as the ‘original’ prototype SJR.

    Cheers, Slieve.

    Hi Slieve!
    Encouraged by your comment on the adjacent, equally interesting thread (The position of maximum camber), I wanted to ask you a question that's been bothering me for a while:

     I know you're into model yachts. Has anyone ever compared SJR (split junk rig) models with UJR (unsplit junk rig) models? Don't you think it would be an interesting comparison? And if not, why not?

    Best regards, Jan

    I understand there are more than 50 with splits, but not all to the Poppy formulae.

    I think Slieve told me there are now over 30 SJR’s.

    So, the trend is upward! 
    And that's good! Because it's a good rig! 
    It just needs to be properly measured and tested!
    And described.

    I looked through the list of members that appeared when I typed in the word "split."

     It turns out that not all of them are owners. Some were owners, and some are only interested.

    In fact, the number might be only slightly higher than the one you provided (14).

    So, the approximate ratio can be: 15/300

    I don't think that is correct. 

    I don't have an up-to-date database but it can be checked. 

    When I last looked a few years ago there were about 523 members or thereabouts. 

    335 had junk rig boats, (including 57 converting and 14 proposed).


    188 had gaff, bermudan or "other".


    (Of the junk rigs, 14 were SJR. That was a few years ago).

    Hi Eric !

    That's also very interesting. I suspect that if we were to estimate the proportion based on forum activity, for example, more than half of the active members would be SJR owners ;-)

    Regards - Jan

    1) a SJR with proportions decided by experienced SJR users, not by those of us who know the theory but not the practice. 

    I entered the keyword "split" into the members list and got 23. There are 584 members in total.

    23/584 = 0.04.

    I might be wrong, as there's still a language barrier in my case, but it's not easy to sew a SJR sail based on materials available on the forum. I know a thing or two about this, as I sewed one this winter.

    I hope that once Slieve finishes his project, the ratio will improve significantly!

    Slieve, please!

    Edit: If you don't do it, someone else will. I hope not me!



    Bonjour

    Most of the JRA members don't own a junk rig or even own a boat. 

    Most members are "interested" in junk rig.

    So that ratio is not realy relevant.

    Well said, Slieve
