    Meritorious indeed, other than the whole foiler thing... :)

    Oh I think you know what I mean - I like the design, and better still the designer, right up to the point where the whole foiler thing starts.

    What design do you like? So you don't like foils? Or the person that thought of them or what? And why just out of curiosity??
    You seem to be having a hard time expressing how you feel-let'er rip!

    I would like to read this article, but for $20/ month I'll have to pass. Pity.
    In my next life, maybe I'll become a "pro" and feel this cost is necessary.

    Boats are so expensive without lifting foils I have much the same attitude as TomD.

    -----------------------
    I'm not sure I understand the concept of liking the design(which is a foiler) "up to the point of the foils"-doesn't compute to me. Browns concept is a FOILER concept-w/o foils it's just another heavy multihull with a very deep prop for the auxiliary.
    PS-the price of the sub for "nonqualified" subscribers is $35.95 a year.

    Dang, Doug. You aren't exactly drawing an enthusiastic crowd, are you?

    Somehow I wound up on the email list for Proboat's newsletter, and I've been thinking of buying a digital subscription to the magazine. Curiosity about the article you mention might be what pushes me over the edge to do it...

    Doug,

    Not enough information to get interested in. Yet.

    ==================
    Thats interesting. In all the years I've studied foiling design and in all the reading I've done never once have I read of a suggestion like Jim Browns. In all the possible incarnations of foilers as "cruisers" it never once occured to me or anyone I know that powering the boat up on foils and then sailing it would be viable. I've got to hand it to Jim Brown-that is certainly an innovative concept. I hope he can do something with it some day. Gives a new definition to the definition of "motorsailer".
    Unfortunately, his idea is only a couple of sentences at the end of the article on Bradfield, but I think it stands out.........

    So would you pull the prop out of the water once you were up on foils, to reduce drag?

    Either that or integrate the prop drive into a foil "bulb"? Many T-foils use a bulb at the joint to reduce drag; I imagine some mechanical guru could figure out how to do it with a folding or feathering prop....

    "Bulb" used on Mirabaud mainfoil:

    I didn't realize it was suppose to really fly. Amazing - what you can do with a computer generated cartoon.
