Signals from Captain Flint

I got this in the mail today from my yacht designer:

Dear David and Susan,

Just to let you know that we have done some work on the INSOLENT-60 design. Though we're embarrassed by the long delivery of this (and other) plans, it does benefit by repeated reexaminations allowed (forced) by the delays. Extended fermentation is indeed enhancing her. We have:

  1. Made the house conform better to the main sheer, with a great improvement in its looks, now reasonably classical -- long low `knock-about' plus an airy matching house.
  2. Rearranged the design of the hinges of the end sections to be much less of a visual excrescence.
  3. Shortened the main hull slightly, lengthening the bow end to the same overall length, to allow the towing vehicle to make much sharper turns to at least an 80 degree angle of trailer-tongue to tractor-vehicle without crunching the boat.
  4. Reverted to a sharp stern, because of easier folding geometries after all, also further de-emphasizing her plywood-based hard-corner shape, improve performance with a stern overload, to keep the stern from being overloaded with friends, and to keep this end as structurally light as possible for folding.
  5. Reduced the maximum (upright!) draft with maximum keel extension to 5'6" -- more useable in coastal environs and with less shift of center of lateral plane between full down and partial up. We have adequate lateral plane area while reducing the overall stresses of ballast wings vs. keel vs. trunk vs. hull.
    The test keel's geometry has been tested in FL on the cradle and we expect any day to hear how the sailing tests went. There were some fabrication and assembly problems, correction of which will save concerns about the heavier INSOLENT keel.
  6. Worked out an option (in addition to the more casual single-hander balanced club jib) for a "speed" double jib rig on the foremast, with a loose-footed jib set to the stemhead and an overlapped and an overlapping forestaysail tacked down on the weather side to form an efficient leading edge slat for the foresail. Sheeting these sails will require a couple of winches, and their use implies at least one hand in or near her bow section. Still this option is compatible with the original balanced-club jib for use when short-handed or not that ambitious. The object was to get as much, and as powerful, a sail plan as possible within the tight dictates of folding everything for trailering. In that connection, we're also proposing to give the fore and mainsails a large roach with full battens, or possibly just very long battens, to bring the total (light air!) sail area that can be set to perhaps near 1200 square feet.
  7. Added shrouds to both masts, mainly to stiffen them against the pull of the staysails. These shrouds likely will have to have considerable drift aft and will limit the squaring-out of the booms, but since with her characteristics she will almost if not quite always gain by tacking downwind this ought not to be a problem.
  8. We have also made some alterations in the cabin arrangement with which the added breadth improve the accomodations a lot. Master'double seems to be around 40" wide/tight. Long skinny galley. Private head. Saloon for 6+ plus two reasonably sized single bunks in `tunnels' flanking the foremast. Mostly just 5' of headroom throughout with a few more some places. True spine-stretching only either horizontally, under open hatches along centerline, or `outside'. All this is a direct consequence of her being an advanced `sporting device' able to do 70 MPH in traffic....
  9. Plus this and that identifying details to be dealt with.

We are gleeful about this insolent project! Sincerely,


The good news is that it looks like I'm finally going to have a design someday soon. The bad news, of course, is that I'm going to have to suspend construction until the whole job situation gets sorted out.

The shrouds are a mixed blessing: gaining 200 square feet of additional sail area is wonderful, and having the masts not fall down is also nice, but unstayed masts would have been much more convenient, especially around bridges, if we could have gotten away with them. On the gripping hand, this materially increases our chances of winning the Chesapeake Bay Schooner Race....

And it looks like we got everything we wanted, accomodations-wise, and a maximum draft of less than a fathom should help a lot. We'll have to see whether the auxiliary helm station inside the cabin works out or not, though.
