    Like the sharpie, even with high cabin profile.

    I think I would still prefer the pop up plan for better cruising visibility, however.

    I would think without the pop up plan you might have a tough time moving forward quickly in a pinch

    Total windage of a low hull with a cabin is almost certainly still less than higher freeboard to make the cabin look smaller.

    And although the cabin looks high, it's a matter of proportions. A helmsman sitting with his feet in the footwell would be able to see over it. This is Southern California and Arizona, not the North Atlantic; I don't need to snuggle him down out of the wind.

    I need to go to an art supply house, and pick up one of those articulated, wooden artist's mannequins. Sitting him at the tiller would give a lot better picture of the size of the boat; it really isn't all that big.

    Question about those headrooms you're citing, Angel. Are those at the cabin sides? Or are they maximum headroom in the center of the cabins, under the crowned cabin tops?

    Once upon a time I had all three Woodenboat books of study plans. I'm not sure where they got off to, but I suspect one or two may have wandered off to Oklahoma with my nephew. I've worked away from home for most of the last ten or twelve years, and you'd be amazed how things get strung out and lost.

    I should bite the bullet and replace them.

    either that or you should use the bullet and get your stuff back


    thats kinda standard in most architectural models
    stick in a few people and cars to give it some scale and perspective
    works like a charm with customers to
    or did before I went broke and the wild world of contracting went to ****

    You can go cheap on the manny with a cardboard cutout.

    That is 4' 8" headroom. I think that's still to much for her.

    It's more headroom then for example in the Mystic Sharpie and the Two-Lucies which are both bigger than your boat.

    IBIS in post#315 is much, much bigger*. You can't compare that with yours. It was just an illustration what color and finish would do for the looks. (BTW, I've added and changed some pics in that post) *51' 4" LOA, 10' Beam, 2' 6" Draft (7' 8" Board Down), 42' LWL.

    I would say go for 4' headroom in the center of the cabin and build a small pop-top on the middle of the cabin. Thats the only place where you need to stand.

    See the Presto 30 pop-top.

    This drawing was in post#106 before.

    Good Luck!

    I was citing the headrooms from the WoodenBoat books. Two Lucies is in 'Fifty Wooden Boats' and the Mystic Sharpie is in 'Forty Wooden Boats'. It doesn't say where but I guess it's measured in the center of the cabins where the headroom is max.

    Cheers!

    I don't have my camera handy, but I've cut things down to about 4' 2" max headroom at top of crown.

    I'm in the process of closing that in now, and we'll see how she looks. I can probably get away with the low headroom since it's going to be a weekender, not a liveaboard. If I don't like the cabin on the full-sized boat when I get it built, it's wood -- I'll grab a saw and change it.

    Good news on the financial end though: I just stashed away the first bit of money for materials. How soon I can build depends on how fast I can grow that stash....

    I would be praying for sunshine in a 4' space although I've spent weeks camping in a relatively small tent
    course I was jammed in there with just the right girl
    usually

    find that camera and lets see the new design

    If you don't like the cabin height, when you saw it off, salvage the roof and try the canvas method using the original cap. Stainless steel zippers and snaps may be worthwhile to investigate.

    Well, it isn't like I'll be living indoors. Most of the tiime inside the cabin will be spent in bed, or setting down inside for a nightcap before heading to bed....

    I was worried about a pop up with an offset companionway but that Presto pop top seems to work.
