What a great idea.  We would love to be involved.  Let me know when it is happening if you want to include me in a Skype chat.

Erutan,

  I've been pondering this for a week now and think it could possibly work out.

  What's interesting is that I can't think of anyone agree with more, and also agree with less, than you.  That probably makes for a good design mix in the end.

  You've done more to revitalize this group, and bring up good questions about materials, than anyone in recent years, and you've definitely been much more useful than I have.  My comments mostly summarize the past, and/or say that I now agree with Rob's choice of X after Y years of doubting it.

  No need to outline where we disagree; we both know it.  If we had sister boats, they'd likely have different cores.  ;-)

  I also would want to work out most of the details in person.  I think I'd enjoy spending time with you, and that we could accomplish a lot over a few beers, coffees, seltzers, whatever.  On the other hand, trying to work things out through email or a discussion forum would likely be stressful.

  How about this as food for thought:

    - If you happen to be in or near Maine next summer, or would like to take a trip, I'll pick you up at the airport, host you for a long weekend.

     - We could go sailing on our current multihul and I could fill you in on all the reasons why the harryproa designs have convinced me to sell it.  You could also experience for yourself some of the pros and cons of "traditional" lightweight catamaran designs.

    - Weather permitting, we could go out again the next day and start hashing out the details.  Or go to a coffee shop, pub, or cabin in the woods, and start settling on the broad strokes.  And/or coming up with areas where we agree to disagree, and the plans would fork.

    - Once we're happy with what we have, we see if Rob and Steinar are wiling to modify the ex40 into an ex48 maxiTrailer if you and I chip in together and purchase a set of plans jointly.

    - We wouldn't actually get plans, but the design would be there, we'd have some nice renderings, and then either of us could get actual plans by paying his remaining half.


  Of course, this would be completely dependent upon what Rob and Steinar would like to do.  It's easy for me to propose that someone else put the cherry on top of what already is a design that's basically my dream boat.

  That said, it's possible that a certain amount of funding could coax the design into at least a basic renderings/vaporware stage.  I wouldn't dream of asking someone to design, for free, the "perfect" boat for a single person, but if the design were paid for, and were for more than one person, it might make sense.

  If not, I'll stick with my current plan of buying a full set of plans sometime in the next few years and asking the questions then.  There's no point in requesting design alterations if I'm not ready to start building.

This is probably exactly my desire. I might add quick set up and take down. But that speed might come from refinement through experience.
I am hoping I can tag along with your mods to the EX40. I think it would be great for HP's to have a pair of sister HP's. Also, I don't know enough about sailing to know what I want, or where I want it, or why.

Perhaps Robs telescoping masts makes sense, as the masts can fit on the trailer. Also the shorter mast is perhaps easier to wield.
