    I think there are a number of solutions depending on ones situation. All of us who have posted have different situations and tend to think in terms of the situation we have ourselves. I would imagine Viking Sized sailors.... from that era, almost never slept straight out but rather curled up in as close to a ball as possible. Funny thing for me is that while I tend to curl up more at home where I have lots of room, I often find myself stretched out in our V-berth... go figure.

    thanks a lot. 
    much appreciated.

    i wonder how other viking sized sailors have solved the problem…

    i have had two boats with a junk rig.

    at the moment i'm sailing a classic catboat with bermuda sail (marconi rig).

    but i would like to go back to the junk sail.

    i am currently looking for a new boat to convert.

    for instance, a marieholm 261 looks great.

    i do, however, have a problem:

    the space for sleeping is lost in the bow due to the mast, especially since i'm 6'2" tall; if the mast is in the middle of the bow berth, i can't sleep there, and the berths amidships usually are too narrow for me, and also often too short.

    how have you solved this problem, if you have it too – how do you sleep in your boats?

    maybe there are also pictures?

    the vertue ("chu–fa") by ute hildendag, for example, has an elegant solution (you can sleep athwart or across), as you can see in the pictures; i know the boat, and even the toilet is right at the front in the bow, that's a great solution!

    but when i'm looking for a "new" boat to convert, i have to look for storage space and room to sleep, too.

    any ideas how to solve the berth problem?


    You can move the mast to one side to create room or you can put the mast at the foot of the bunk and rake the mast forward to get the masthead in the right position for the sail.You could even combine both measures.

    David Tyler raked the mast on Annie Hills old boat Fantail a Raven 26 and I did the same on  Frederic Elso's Hogfish.

    I can recommend putting the mast off-centre.  I've had two boats with this solution and it was never an issue.  (What is truly astonishing is how few people even notice!!)

    thanks again. 
    very insightful. 
    also helpful. 

    now, my forst boat was a kingfisher 20 jr. 
    there was no way for me to sleep in it.
    the second one was a converted trident 24, also with losing the berth in the foreship due to the massive mast. 
    in both cases it was nice to have more stowage, but sleeping still was a problem. 
    at my age i like it to have a little comfy. 
    and yeah, yeah, i know, real sailours are tough guys and stuff… 
    but some things i don't need any longer. 

    as i already mentioned, i'm looking for an allrounder with enough room to stand (headroom > 5'8") and sleep (berth longer than 6'23", and wider than 2'6") which can be converted to junk rig without losing the space to sleep. 
    the boat also shouldn't be heavier than 6700 lb.

    the kingfisher jr was flat, the jr of the trident already was slightly cambered. 
    so the idea of a split jr sounds tempting.
    the easy handling of the jr is most compelling to me.
    so i wonder, which boats maybe suited for the split jr where you can use the original place of the mast, or even the old mast itself…?? 

    anyway — how do you guys sleep in your boats?

    George: "...but doesn't the split/aero junk has to handle more lines?"

    Len: "My understanding was that the SJR used less lines not more..."

    Neither generalisation is strictly correct.

    There is nothing magic about the split itself which makes the sail any easier or more difficult to set.

    In addition to the mast parrels and the sheeting, contiguous (unsplit) sails seem to need extra parrels to hold the sail to its right shape - sometimes these parrels are the "running" type which means they may be "handled" (adjusted) from time to time eg after reefing. Generally speaking, a split sail would be no different.

    The Amiina SJR may be a special case, not just any old junk sail with a split in it. With its low yard angle and higbalance, and the proportions of the sail which have been carefully calculated, the horizontal forces needed to hold the sail in shape are minimal and none of the normal parrels (standing or running) are necessary. The sail can be made to drape perfectly under the sheeting forces and gravity alone - almost, but not quite.

    Not quite, because the other special feature of this rig is that it uses spanned running parrel-downhauls instead of the usual standing mast parrels (either long or short) which used by conventional sails. These running mast parrels undoubtedly also play a small part in getting the sail to drape correctly. On the usual 5-panel version, two of these are needed, and they are adjusted each time the sail is reefed or unreefed. Just a tweak is needed, and it may be done at leisure. But they are "control lines" none the less, and are part of the deal.

    I guess we could generalise by saying that both a split sail and a contiguous sail will need extra control lines of one type or another. A badly designed SJR might well require both types.

    (PS it might be possible for the aerojunk or some kind of hybrid to do without any extra control lines, where there are "hard" batten parrels, in the form of wishbone battens, or the D-former or "ovals" seen recently eg Serenity (Boat of the Month Sept 2023).  I don't know about either of these types from direct experience. Generally however, there is "no such thing as a free lunch").

    By the way, George: in addition to the suggestions made by Len regarding mast placement vis a vis sleeping arrangements: it is not unusual for a junk rig to have the mast offset from the centre line. The sail itself is slightly offset anyway. Off-setting the mast by 20 or 30 cm would not affect performance in any measurable way, and may be a solution if the mast appears to close to the "heads" or a berth or a  vital companionway.

    Along with the range of mast positions fore-and-aft (by considering the range of mast-balance of the rig, from about 10% to 33% depending on the rig) you might also have a little offset athwartships as an extra variable to play with.

    I think I have not quite got that right. While the centre of area is calculated with 100% jib, it is quite common to use the total sail area of the junk sail with a 130% jib as the JR has only one sail to act as mainsail, jib and spinnaker.

    thank you very much, indeed. 

    so, maybe a split jr might be a solution…  
    …sounds promising…
    and yes, it's either single–handed or with two persons.

    but doesn't the split/aero junk has to handle more lines?
    or, more important, how do i find out which boats are best suited for the split rig?


    My understanding was that the SJR used less lines not more, however, the whole write up is here:

    https://www.junkrigassociation.org/slieve

    However, I would first find your donor boat to convert and find it's designed centre of sail area and total sail area with a 100% jib. (in other words do not include any foresail area behind the mast) Then draw out various junk rig sails of the same area to the scale of your drawing.  I like to play around with the drawing printing it out to one of the scales on my triangular engineers scale normally 1/4in = 1 foot (or the metric equivalent) so it fits on an 8.5x11in (US letter) sized paper. Most JR sails are close enough to having the centre of area half way back from the luff so line that up with your mark from the old centre of area. For preliminary mast placement, the sail can be drawn as a simple rectangle. Now draw a line straight up from various places it might be ok to stick the mast, remembering that the mast will be 6inches-ish thick. If any of those places are within 5 to 20% back from the luff, use an "Arne" style sail. If less than 5%, the mast is probably too far forward.... not likely to be a problem ;)   See: https://www.junkrigassociation.org/arne Both the multi-pdf article at the top and there is a document with 10 master sail plans ready drawn. I had thought Arne had some drawings for  larger balance sails as well with a lower halyard angle but I don't see them there, maybe I missed it. Anyway, this set includes a detailed set of articles with all the rigging, mast sizing, etc. that you may need.

    If on the other hand, you are looking at more like 25 to 33% back from the luff, a SJR might be the better option, though the author feel 35% might be fine too. If your mast ends up much more back than 33%, the sail may not weather cock when the sheet is let go. Note that with the SJR, the sail area includes the slot between the jiblets and mainlets.

    In any case changing the AR of the sail (effectively changing the boom/batten length) can be used to fine tune where the centre of area of the sail might be in relation to the the mast. There are, of course, limits to mast height for obvious reasons or boom length so that the sheet has room to work.
