    I can testify to that! It seems I buy a "fixer upper" and spend my time replacing/modifying the damn things...or buying a perfectly sailable boat and then spend my time replacing/modifying that instead. And I crib about my better half having another pair of shoes hidden away. I passed my mid age crisis 20yrs ago so can't blame that.

    A boat in the water is worth 5 on the land!

    Yes, Paul, my experience is that two boats is one too many, always.

    Now you really have got me thinking! Will be giving this some thought over winter.Appreciate your interest. Coincidentally, my other boat is a Nic 32.which sits beside my Van De Stadt and 17ft trailer sailor. I have to stop collecting, she says!

    Having had a closer look at the Great Dane 28’s data, I think she deserves her own thread, so I jump from the Magazine 84 thread to here.

    At first glance, the GD28 looks quite normal for her time, not very dissimilar to my IF, Ingeborg. However, her displacement (3800 - 4200kg) puts her among the real heavyweights.
    Her Disp./WLL. ratio is around 400, which puts her in class with the Nicholson 32 (Ingeborg: 270).

    The description I find about her (in Swedish) indicates that she was designed for serious ocean travelling, but it also indicates that she is under-rigged for normal sailing.
    Her SA/disp is around 13.  This is where the JR can help. Even with a shortish mast, as shown below, the SA/disp. can be brought up to over 16, which is decent. With a camber/chord ratio of 8 – 10%, she should move well, and no doubt sail in rings around an original sister boat.

    On the sailplan below, I have reduced the boom length from 5.2 to 5.0m to bring the CE a bit further forward. In case I have overdone it, the whole sail can easily be shifted a good deal aft, to get her in balance. How tall the rig can be made, depends of available mast material. I guess I would not go higher with aluminium or wood, but a light and strong carbon mast could justify a taller rig.

    The traced hull and in particular the underwater hull has been taken from quite low-res diagrams on the web, so are quite inaccurate, but hopefully they are good enough for this exercise.
