    You can design more sail area than the standard BM sail area, add 10% or more, as the JR is easily reefed. There will always a time when you wished you had more sail, best to build it big in the first place. I would think a stiff hull like a Spray could take a pair of very tall masts, whatever it takes to get the desired sail area.

    You'll need a lot of sail area to drive that hull - Sprays typically present a problem with getting enough sail area on a schooner rig that fits the length of the hull. I'd want a minimum of 1250 sq feet on that boat. More would be better.

    I have a small manufacturing company and I design in an autocad based software so dimming the sails will be relatively easy and drawing the basic hull beam view likewise.

    Thak you guys for giving me a starting point. i do have drawings but the sketch of the jr is not dimensioned. i was told by the builder of the boat that it needed two 45' masts and my plan was multi sectioned aluminium straight tube. Hence my need to be here before i do something really stupid. keith

    Hi Keith,

    On a steel boat, it makes sense to think about steel masts.

    Here's what Paul Fay reported (August 2013) "... street lamp post manufacturer Fabrikat who are in Nottingham make tapered lamp posts and are happy to alter them for use as masts. The masts on our Ti Gitu were made by them and although it took a while for them to be processed through their system the end results are great. Nice taper - additional straight section at the base - hot dip galvanised and then painted. We are really pleased with them. If you need any more info my number is on the Fay Marine website"

    If the boat came with a set of sails, I guess you are stuck with whatever sail area they offer, but the good news is that the Spray will make an excellent motorsailor anyway, and junk rig is the absolute perfect rig for motorsailing.  I've done a lot of it on my 24 foot, 5 tonne Tom Thumb design, Arion, and the combination is brilliant.  Also, off the wind, the Spray is surprisingly easily driven, and the junk rig powerful and effective, so you should have no problems sailing anywhere from 70 degrees off the wind to a broad reach.  I have no experience with sailing on a dead run with schooner rigs so will let others advise you on that (there are several diverse opinions on the best tactic there).  If you measure your sails, it will provide a reference point for JRA members to advise you on mast, yard and batten specifications.

    Hi Keith

    I assume the sails are junk sails? Do they have Yard/battens/boom?

    First thing you might do is to measure them up accurately and draw them out. You can then check them against masts drawn in the appropriate location on a profile drawing of the hull. This will allow you to calculate the required dimensions of the masts, depending on the materials you choose.

    Hi guys Ive recently aquired this boat and it was intended to be jr. it has mast housings and new sails but no masts or rigging. i have no idea what im doing but have read jr v bermudan in considerable detail and have decided jr all the way. All i need now is a ridiculous amount of help.
