    Three different boats by different designers ;)

    That said, the best sailor would be the v/d Stadt 34 in my view as I had built a few of them. Lightest of all three with generous sail area.

    For bad weather I would go for the Koopmans, then the Dixie and lastly the v/d Stadt in that order.

    Ease of building; only one contender really, the v/d Stadt 34. One can put a hull and deck together all welded up in 3 weeks without breaking a sweat. And it has the best set of plans to work from, period.
    The Dix has to many chines and the Koopman's I really cannot comment on since I had never built one before or seen one.

    Ragtime sailed in this years Sydney to Hobart. Google up the event, there was some photos of Ragtime during the race.

    I know this is an old thread, but I had to revive it because I believe Wynand has not done Dudley Dix's Pratique 35 justice.

    If I had to guess I would say the Pratique is the saltiest boat of the bunch due to it's robust, conservative underbody and conventional transom. Although slightly smaller than the Koopman's, the Pratique has a keel with a larger surface area and would probably provide much better handling in rough weather. The Koopman's has a reverse transom that does not protect as well against waves from behind when running. The rudder and propeller are also better protected on the Dix and the rudder also appears to be more robust and easier to service. On the downside It's almost certainly the slowest of the three.

    As for ease of construction I wouldn't say the Van De Stadt is necessarily easier to build than the pratique. Both have the same number of chines, both have similar deck complexity, both were designed using cad, and both are available in pre-cut kits.

    For offshore passage making I would personally choose the Dix over the others. It's significantly heavier than the van de stadt and probably has a more comfortable motion, and it's the most conservative design of the group.

    Captain, have you ever built a steelboat yourself??

    For the record - Dudley Dix and myself are were good friends when he was still living in South Africa andI still mail him from time to time and Im on record as being an avid Dix fan. Had built from his designs the following sizes; the Dix 38 (which I commissioned in 1991) Dix 43, Dix 57, Dix 65 - the latter two boats featured on his webpage.
    And from other designs a had built quite a number in radius and multi chine.

    V/d Stads I had built a few and believe me when I tell there is no other steel boat out there that can beat the speed and ease of that particular design and build method. It is actually build in a former jig so to speak. Nothing to do with CNC cut plate which I personally avoids like the plague.
    Also, the Dix 35 is framed, adding to the build a lot of extra work - building the frames, strongback, lining up the frames that leave room for error, adding longitudinal stringers before plating can begin.
    Now plating - more chines means more work and welding period. And all that tringers and frames must be stitched welded to plating.
    No way you can make an uninformed statement that the Stadt does not necessary build easier than the Dix...

    As for the plans - I had many plans from many designers through my hands, and the v/d Stads plans are the best in the world, period. You have to see and compare the quality of sketches, detail etc to appreciate this.

    Nope,

    Never built a steel boat, just tiny wood ones. Never even sailed more than a couple of miles offshore. I have, however, done a ton of metal fabrication and welding (more tig than mig).

    I just happen to have read a few books on boat design and I happen to like the Pratique. Super informed? No. Supremely qualified? Nah. But I think I'm making a pretty good guess when I say the Pratique is the best boat of the three for rough conditions.

    And for the record I believe you about the Van de Stadts =)

    Captain, In my view all three are excellent boats and each would excel for the purpose it was designed for. It all boils down to seamanship and abilty of the skipper in the end.

    That said, when doing and extended cruise you basically have two schools of thought. The ones that would want to get the passage over as fast as possible, even at the cost of some comfort and this is where the v/d Stadt would make sense. The other is people that do not mind taking longer, as long as the trip is a more sea kindly one and here the Dix and Koopmans would be the boat of choice. At the end it all boils down to personal choice.

    The Pratique 35 was originally built by Ankon Boatbuilders in Cape Town, South Africa in the mid 80's and was one of Dudley's earliest designs professionally and in my view the design that put him on the map so to speak.;)
