    fat coamings

    Tony, I really love those coamings!
    Your modeling is to my eye very pro (as in profound) - from the eye-pleasing fronts to curvaceous back. For instance: adding a bit more arch to the traveler 'coaming' across the back is masterful. Really.

    Ability to find a higher place to sit in the cockpit area is an important safety concern. Especially if the perch is comfortable.

    You'll remember Zoltan saying, when asked about his huge cockpit on the Commander, that it wasn't a concern for him because as much green water that came aboard in rough weather got tossed right back out of the cockpit.

    Have a similar problem with getting rid of green water with my remodel in the back of the cockpit on A338. We have to find a way to get water out quickly, VERY QUICKLY, when the water gets higher than the companionway threshold.

    I'm not sure that an OB Ariel can depend on the OB well as an ultimate scupper. It certainly is that. But as Zoltan implies: as much water enters the cockpit as exits. It is, however, those split seconds when inundated that the water getting out might also be getting below. And there are I-don't-know-how-many-stories of water getting in to the cabin. Who's to say that in the excitement the drop boards aren't also going overboard.....?


    My mahogany extra-tall coamings got screwed up when being surfaced by me. Asleep at the sander was I. So I am thinking of blatantly copying those marvelous coamings of yours.
    BUT the way I go I'd get totally focused on the problem of fabricating fiberglass moldings and it would take me another forever to come up with something at least comparable to yours! There are a lot of good curves that could indicate a relatively light molding. But then there's the wood on top and the bracing for the winches....etc...etc.

    Regular coamings that extend above the companionway, on other boats I've seen opening scuppers worked in. Deck level scuppers that only open with pressure from the cockpit side. Not at all sure if they would have enough volume capability. Or if they are really efficient?

    Water weight and height in the cockpit has to be GONE immediately.
    There's some math to figure the volume of weight a cockpit contains, it's huge. Enough probably to cause some strange and dangerous trim problems - when too many problems are coming down.


    Anyway, just tossing this in to boost your paranoia tolerance
    Looking good!
