    Here you find more informations about the Ha'penny20:

    By the way, my Farthing is still for sale.

    Another of Mr. MacNaughton's designs that deserves a further look is his Clarsach 20. It's thrown at his design students as a difficult exercise in fairing complex surfaces. As it's a canoe yawl, it gives up some cockpit room to the Pennies. Mr. MacNaughton designed it as a coasting weekender, with bilge keels. It probably won't find much traction in the US. It would be a perfect boat in locations with high tides like the Bay of Fundy, the far North, and many locations in the UK and Europe, as it can "dry out." It's also shoal draft.

    There's a lot to be said for a pointy stern, perhaps as much at anchor as anywhere. Although the C20 is drawn with a yawl cutter rig, I don't suspect it would take much for a junk conversion.

    As with all of the MacNaughton designs, it has a classical sweetness. Part of the way down here:

    Tom's suggestion for 'below deck' steering in my case was an extended Jester style tiller that ran through the transom via a neoprene sock which could be operated from either a comfortable seat or standing with one's head and shoulders through a hatch.  The 'above deck' steering was simply lines brought forward along the deck from a quadrant on the trim tab; it was reasoned that if winds were too light for this arrangement to be effective the yacht would be propelled by yuloh.

    Yes Tom writing about The Coin Collection

    This series brings together a unique combination of traditional and modern elements to produce a range of boats optimized for offshore safety and comfort, ease of handling, excellent accommodations, and high performance of the type that is valuable to cruising people. Sheathed Strip construction is standard.

    The distinguishing characteristics of the series are:

    1.) Modern heavy-displacement hull designs of the full-keel type, for best comfort at sea, good steering characteristics under all conditions, good load carrying capacity, and consistently high speed, especially in very light and very heavy air and on long passages.  All this in family sized yachts.

    2.) Chinese lug rig for full sail-handling capability (raising, lowering, reefing, unreefing, and sheet handling) from the helm, without touching the sail, optimum sail area under varying conditions without changing sails, consistently high performance, especially on passage, and low-tech simplicity and reliability.

    3.) Flush deck design for maximum interior volume, ease of interior customization, versatile and roomy deck space, strength, and simplicity.

    4.) Steering and sail handling from on deck or from the shelter of the enclosed steering station.

    This is such a type of boat I want

    I could echo Timothy's words.  Tom helped me with plans for a 19' junk-rigged design that was essentially a scaled-up Farthing, and there was a lot of to-and-froing while I made a cardboard mock-up.  "Old Irascible' went beyond the call of duty, patiently answering a barrage of questions and supplying drawings whenever a concept was unclear.  It seems that few of his 'coin collection' boats have been completed, but those that I know of have been praised for their seaworthiness and interiors.  Tom is a vocal supporter of what he calls the 'Chinese' rig and promotes it forcefully.

    I know he has long been keen on drawing a junk-rigged voyager of around 19-20 ft; great to hear it's underway.

    Mr. MacNaughton is a great man. He can be slightly grumpy and occasionally hard to deal with, because he has an exceptionally strict sense of honor and fairness, as well as a broad intelligence that lends itself to not only yacht design but also to that of aircraft and I suspect many other things. I am a minor student in his Yacht Design course.

    My feeling is that a MacNaughton design may not get you there first in a race, as he appears to give little regard to an absolute "need for speed", but he dots all the Is and crosses all the Ts in regard to stability, comfort, and seaworthiness. Not to say the boats are slow. I suspect they are as fast as a full-keeled cruiser can be designed. Mr. MacNaughton is obsessive about fairing, and applies a great deal of science and hard thought to things like the interplay of the keel and the skeg and rudder.

    I have read with great interest that Tom MacNaughton is designing a Penny 20

    I wrote to him to hear how far he had come with the design,and he answered.

    Dear Carl,

    You should be able to buy Study Plans in a few weeks.  We are working out the Concept Drawings and an "Article" on the drawings.  The only difference between these, when they are done, and complete Study Plans is that the Article at this point not only describes the design, but also has a lot of information that later will be moved to the drawings.  Things like block sizes, suggested sources and so forth.  It will also probably not have the "evocative" section that I normally tack on the end which describes the feel of being aboard her and sailing.

    I'd say email me once a week and I'll give you a bit of a progress report.  Then, when we have completed the Concept Design, we will be happy to sell you Study Plans.

    At the moment I am detailing the rig on the Profile and Rig sketch.  I have the source model for Perspectives of the hull lines done and we'll be producing several views of that once the Profile and Rig sketch is done.  During this process we've worked out quite a lot about the Accommodations Plan.  Tick marks on the Profile and Rig sketch show where cabin soles are, where bulkheads are located, and the height of major items like counter tops and bunks, etc.

    She has a remarkable amount of room.  Rather more than I thought she would.  I thought of her as a minimum liveaboard voyager for one person, with the option of a visitor.  I think now I would eliminate the word minimum.  The only major thing she doesn't have that you'd see in a larger liveaboard is a dedicated "office" space.  I'm keeping that in mind when I design the interior as it would be nice to have some provision for comfortably using a laptop computer for extended periods so that a person could write articles, update a web site, or whatever.  For someone accustomed to working on boats there might be room for a tool box of hand tools which might aid a sailor in getting work at boat yards and boat builders along the way.
