    Remember Achieng from a few months ago, the motor sailer with the old tarp sail?

    I just got an email from Nils: Here she is with her brand new professionally-made sail - looking good!

    Well, Graeme, you were asking for a comment  -  so here it comes:

    I won't address the rig, there are many different forms it could take.

    But the hull: Aesthetically, I wince. I shudder. I avert my gaze. Those vertical topsides.

    ["but SibLim has vertical topsides!" I hear you cry. Yes, but with a chine above the waterline, and a spring in the sheerline. Makes all the difference]

    On the other hand, I drooled over Rudolph's Scou all the time it was featured. Still with a flat bottom, but with flared topsides and then a tumblehome that is perfect for mounting a leeboard.

    Both boats with flat bottoms. One with a keel that negates the advantage of a flat bottom; the other with a little bit of a skeg, retaining that advantage of being able to float on wet grass, but still with the ability to bounce on a stony bottom.

    As regards those Moth-types:

    My last racing dinghy, 47 years ago, was in the International Moth class, and was a pretty little round bottomed GRP boat somewhat like your Zephyr and the Europa Moth. Not really competive against the more extreme narrow-hull+hiking-wings and scow Moths that were just coming in at that time, but nice to look at, nice to sail. The scows had to be sailed on their ear in light going, to get the wetted surface out of the water., not so fast to windward but streaked away downwind in a breeze. Then there was the British Moth, which had a bow much like your NZ trading scow. Heavy, not fast, but a good trainer for youngsters (that has now been superseded by the Topper and similar types).

    I have always liked Phil Bolger’s writing and have found his designs more than interesting. I have his ‘Boats with an open mind’ and also his “100 small boat rigs”.

    I have studied the Micro before, and now it struck me that I would give the rig a radical makeover.

    • ·         The original keel is probably not super-efficient to windward, so by moving the rig aft and adding a big, balanced rudder with a perfect foil shape, I kind of get the benefits of a new centre-board without being bothered with the cb. trunk.
    • ·         This gives access to the mast and the whole sail bundle from the cockpit. Hoisting and reefing will be super-easy.
    • ·         The sheets moves out of the way. Tacking and gybing can be done without ducking our heads.
    • ·         The rudder ensures reliable tacking, every time, and will improve the performance to windward.
    • ·         A new door in the front of the cuddy could give easy access to a most perfect anchoring (or children’s) cockpit.
    • ·         The boat will probably sit quietly at anchor with only the top panel set.

    To make this work, a big, stout rudder will have to be built and added on the stern. This can be made in several ways, but it has to be able to swing up when hitting granite. The shown one, at 0.5sqm, may be a bit over the top, I don’t know. Since it will have to share the transom with an outboard engine, it should be offset to one side to let the ob. stay on the cl. The mast is also offset to port, just outside the companionway hatch, but without interfering with the bunk. The moving of the rig this way may call for moving the ballast forward, but that should be doable..

    All in all I think this new rig would turn out to make the boat both faster, handier and safer than the original.

    Maybe its an acquired taste - to me she looks great.

    I just love these simple flat bottom hulls, which can sail quite well in sheltered waters. In fact de skou  (of two months ago) with her large sail area, ought to be a little rocket ship on the canals.

    More decades ago than I care to admit, we used to have in New Zealand two very popular 11' dinghy classes. One was a strict one-design called the Zephyr - they were the most exquisitely shaped cold-moulded round-bilge dinghies. They were built, and often varnished, as objects of beauty. The first couple of hundred all came off the same mould and in fact all built by the designer, if I recall. They were (and are) very expensive and today they are a classic "collector's item".

    At the same time there was the more open-design 11' "moth" class which came to be dominated by a crude flat-bottom, plywood-panel scow known as the Aussi Moth Mk ll. They were cheap, easy to build and plenty were built, but I doubt if any have survived.

    The two types (and their owners) never seemed to mix. 

    The exquisite Zephyr (above) and the ugly Moth Mkll (below)

    Eventually a challenge was issued, and a race set up between the Moth Mklls and the Zephyrs. As it turned out, there wasn't much difference in their over-all performance.

    Arcadian is in the same size bracket as Colne Spray, she is 50 feet overall and weighs 17 1/2 tons. She sets 1200 square feet of sail, 500 in the foresail and 700 in the main. When doing the conversion to junk rig I installed two vertical capstan anchor winches on the cockpit coamings, one each side. I arranged the halyard from the foresail to starboard and the main to port. Each mast had a halyard with 3:1 purchase, and a yard hauling parell as moving lines. She had fixed luff parells, a mast lift and a downhaul on each mast. The topping lifts were cleated off on the booms to provide an additional support for the boom, they rarely needed adjustment. The electric cockpit winches could also be used for stern anchor or mooring lines and were also used for lifting the dinghy on the stern davits.

    I was able to sail her on my own despite being in my late sixties and with back problems and heart issues. She ended up being faster under the junk rig on all points of sail except hard on the wind and could be sailed by one person as compared with the four it took to sail anything like efficiently under the original Bermudan rig. We made the sails which were flat cut Hasler/McCloud type, they were good when the wind was over about 7 knots. Cambered sails would have improved her performance quite substantially in light airs. The battens were wood and we broke several on the mainsail (21 foot six inches long) when doing involuntary jybes, but we had no problems with the shorter foresail battens (17 foot six inches long). The foresail was double sheeted after the original single sheeting hung up on the mainsail battens one too many times!

    my wife's mobility issues eventually lead us to sell her, otherwise we would still be happily living aboard. Her new owner happily lives aboard in the Town Basin Marina in Whangarei and sails her frequently, including winning the Tall Ships Race in Russell three years ago.

    In case the bowsprit counts, and even the pulpit on it, then I find the overall length to be 51'6".
    That makes sense  -  and the hull length of 45' and SA of 122sqm begin to look almost human...

    Good luck, Hazel.

    Another approach (same result)

    The main mast is said by the draftsman to be 15m from the deck (49.2')

    At a glance, from beak to transom, the hull length in the drawing is less than the length of the main mast..

    Hazel, are you measuring L.O.A. from the end of the bowsprit? That works (more or less.)

    Otherwise, there is something  slightly wrong with the drawing I guess.

    I’ll measure again, if I remember right it was from transom including bowsprit, the yard wanted to know because that is what boat charges were based on, Allans drawing was for a refit , re rig so it’s possible there’s a discrepancy there.

    Funny that!
    Now I had another go: I imported the sailplan into QCAD and scaled it up until the battens of the mainsail became 5050mm. The battens of the fore and mizzen followed on and came out right within a cm or two. The sail areas of each sail also fitted with Allan B’s numbers.

    The only problem is that this exercise resulted in a hull length of 45’. What am I doing wrong?

    Clearly, Colne, as built, is 52’ (Alan B says 50’ in the description).
    One way or another, the boat (and rig?) has been built larger than the plans  -  or ???


    PS: What the builder may have done, is to just stretch the hull without expanding beam and draft, just as was done with Samson. If the builder then used the sails as Alan drew them, there would suddenly be much better room for the sheets. That would be an overall improvement.

    Hi Hazel,

     I can’t wait to see Colne Spray Sailing on the Blackwater, I reckon she’ll be a majestic sight, especially if there are any Thames Barges around for you to joust with.
    I’m  in the process of converting my Sadler 25 - BooTwo  to Split Junk Rig. She’s  down at Marconi SC on the south bank.
    I believe that Poppy, Slieve McGalliard’s former  boat and the original SJR, is currently at Brightlingsea, so with Colne Spray that will soon be THREE junk rigs on the Blackwater.


    As a novice I can offer no advice, but what I absolutely love about the JRA, is that others can, and do which, you are already finding.


    As you say, wow I’ve spoken briefly with Tim on Poppy, also Richard owner of Bekanti a 40’ Spray who is close by, unfortunately he and his wife have not used her, due to advancing years, and the boat has not moved for awhile, I intend looking her over ( no I don’t want another project ) What has kept me going is as you say Colne Spray will look majestic, and being in the shadow of the EDME it will be interesting, Andy her owner has been supportive, although a bit miffed they lost the last race of the season, beaten for the first time in nineteen years, the yard was in deep mourning. I look forward to meeting up, it will make a fine display ( Battle of Britain Flight ? )
