    Very Cool. Why don't you make it an articulating prod? You can pivot on the headstay post.

    carbon fiber sprits

    Seem to be out of the loop here. But I've been looking at the Trogear A-sprit. Two tubes
    ideally coming from the bow slightly below the toe rail frpm either side of the bow. Can
    be mounted on top. The A frame legs have only 15 degrees of separation, making it quite
    narrow. Have not trialed with mockups but believe it won't go much further inboard than
    12/14", where it will have a fiberglass tube and a long 1/2" bolt from side to side so that
    the sprit canbe raised and bungeed to the stay. Has a 1/2 bolt thru holding the Sprit
    weighs 5lbs.

    The bobstay is shown in the literature is a modern guntackle - led aft to the cockpit! In
    preliminary emails with Trogear, it is possible even to have a 'simple' rod bobstay, no
    turnbuckle and chain. Don't know yet how actually it's rigged. But like the simplicity.

    My mast has what I think is a true Solent tang about 18" below the masthead fitting.
    That stay will go to the stem fitting. Think it possible to rig this stay permanently,not
    readily removable. And have reefer/furlers on both stays, or a hanked on staysl and self
    contained asymetricals or screechers with their own attached furlers...?

    Also, the top long bronze bolt of the original stem fitting that goes thru the fitting to pop
    out conveniently on deck is the strongest method I've ever seen. I had mine recast with a
    fatter five-hole fin to take pin and stay loads better. Original toggle holes were elongated.


    Those Trogear A-sprits are extravagant. Already have a self designed aluminum sprit that
    I really like. But it's too heavy for the bow, too much for the boat. Shave 20lbs first off
    on bowsprit alone. 5lbs, or more, on lighter bobstay gear. Anchor gear on deck will be
    easier and maybe lighter with the bowsprit free and not part of foredeck clutter.

    If I keep the hinge-up option for the A-sprit, the sprit can be folded up to pulpit making
    sail attachment and retrieving easy. Something recent events make quite necessary.
    "Easy does it, and if you can't go easy, go as easy as you can." Gertrude Stein

    Couple coats Aluthane will make that $$$$$ snooty black carbon tube look like a good ole
    aluminum spar!! Imco.

    wow, that is a nifty bowsprit, though I dont see what the pivot is about. The Trogear is a pretty nice bit of kit as well. However, I am making a permanent bowsprit for the forestay. Currently, I have decided to set the distance at 18" from the bow, nothing extreme. As I said, I am trying to balance the rig a bit without having to shorten the sail area... some of you all are probably rolling your eyes. Nonetheless, I work at a metal fab shop and so far this little experiment has cost me nothing.

    as a side note.. I am taking on more side work (design & fabrication) as I begin transitioning myself towards opening my own shop, so if any of you guys have some fab work let me know. For example, one thing I was thinking of making extra are some SS trim rings for the aluminum opening ports. The cast aluminum trim rings that I have are in many pieces. I am going to laser cut 12ga SS ovals... when I get a chance

    Talk about nifty. Laser cut, I don't know the machine. Is it like a CNC that you program with
    a computer / Shop here has one of those (personally don't know how to program any
    computer) but it cuts with regular milling bits. What I'm asking: can you program individual
    jobs? I had my aluminum opening ports powder coated. Because the coating is relatively
    thick the trim ring now no longer slips over the spigot. Everything could remain the same
    spec but the inside oval has to be slightly bigger, maybe a 1/32" all round. Would you
    provide the fastener holes also?

    The Troger A-Sprit can be mounted on deck, or as it happens, on the molded toerails, at
    that height. That means one can micro adjust how much the bowsprit will project out.
    They have end fittings. The preferred way is to mount the A-frame outside of the toerails.
    Because the A-Sprit 15degree angle is not adjustable, that means because it is narrow it
    is fastened pretty much forward on the bow. And down enough so the a fiberglass tube is
    glassed in thru the bow (when you look into the forepeak you'll see it). A long bolt, possibly
    threaded rod holds and hinges the spirit on, so it pivots. Or you can permanently mount it.

    I had some preliminary email discussion with one of the A-Sprit designsers about permanently
    mouinting the sprit. My thought is that carbon tubes are not really good in compression.
    So I understand. But did get qan OK to use their thicker wall tube model... at a thicker
    price. But then it occurred to me to axe the Solent idea, and use the inner forestay to rig
    that mast at higher tensions.. And use the jibstay with light weather larger sails with the
    sheet winches. Like the idea of folding the sprit up to the pulpit and attaching or removing
    sails. And paying less for footage rent in marinas.

    Best of luck with your new business!!!

    You start making S.S. port lites I might be interested in a set.

    ugh. its been a while since i have worked on the boat, even though I see it everyday sitting in my shop. Even more annoying is Photobucket forcing me to pay for 3rd party hosting of all the build images.... so lame. I was emailed by a gentleman who wanted to see some of the images of the build, I had not put 2+2 together to figure out why he was not able to view the images on the forum.

    anyone have a silver bullet? if someone can give me a good solution I swear I will do some work on the boat!
