    I can't understand why you would want to use a 4X8 sheet of anything to lay up glass strips or patches. Most work considered is in the order of smaller areas. Go to your local window repair Co. and buy a glass window pane to suit the size of the job. Or if you are really cheap, go to the tip and find an old mirror. Clean it up and do your layup on the face of it. (Wax it first) ;)

    Would it be worth contemplating eglass or cf laminate to replace the strength of the bolt in the DB case?

    Or is the bolt there for some other purpose as well?

    Personally, I'd take the opportunity provided to replace the DB with a CB, as it's clearly going to hit the ground again if it's done it once already, and with such destructive effect.

    That's what I'd be doing. YMMV

    Yes and maybe the glass shop will have a cheap or free work bench to put it on as well? Haha But yeah there's a million things that will release like wax paper, plastics, glass, lexan, carbon, electrical tape! (my fave in a pinch) also aluminum foil! or many others. But the mdf, or melamine even better, is also a sturdy large workbench, and can be used and cut up into useful jigs or clamps later as well. Handy if your essentially working in a parking lot and do need to. Do a large part.And can be had every 1.6 miles from depot or lowes. He's looking to get in and out fast so a 4x8 he could make and lay up all parts of board and box on one 4x8 quick.

    Side note: took a look at depot and melamine is only 12 bucks more at depot, so yeah! skip mdf go right to melamine.

    If one were to lay out 1/4 inch fg/epoxy panels and use them instead of coated plywood, would it be heavier/ lighter, stronger/weaker? Just curious, because I remember reading years ago about a boat build where you laid up flat sheets and formed the boat from them.

    Again I'm sure others smarter than I can chime in, but I would think weight and cost would nix that right off. You can calculate glass weight if you just look at cloth you wanna use then resin to match, heck most times ha just look at the jug of resin your gonna throw at it and how much that weight is. And either way 1/4 inch would be overkill I think. But the ply is easy to weigh out, as example look at 6mm 2x8 18 pound total, there's 32 sq ft in a 4x8 so 32 divided by 18 tells you 6mm is 1.28 lbs per sq ft.

    I'm pretty sure that a properly "cored" panel is almost always lighter than pure glass (grp) lay up, not to mention not buoyant at all.

    That 6mm ply you are building with is about as light as it comes unless you are ready to up your investment probably x4 or x5 to go with a foam/nidacore and carbon and vac bagging.

    Notice Gary always sticks with ply in this size range, its hard to beat it!

    So, probably the only advantage would be less chance of rot at the expense of more weight. And maybe resale value would be better with an all fiberglass boat.

    Inserting the box

    Thanks for all the advice guys. Sorry outside the box I didn't see your post offering to help with the repair until now, and I'm waist deep in it at this point.

    I have the new box built, but I noticed on os7's new plan for the vertical trunk that he moved it back to frame 5. Well I am leaving it where it is, it's only a few inches forward, I'm guessing that it will give me some weather helm, maybe I'll try rakeing the mast back!

    I'm going to be installing the box today, got some hex standoffs that I can approach from each side for the replacement bolts.

    I'm putting a second round of 1-1/4" square stock around the case and keelson so that I can screw down into the keelson.

    My phone is on the fritz so no pics right now.
    As for the mdf debate, I just put down wax paper and it's perfectly fine.

    Hoping to splash Friday but I might keep it over the weekend to let it dry further before I apply bottom paint. Extra $150 for three days!

    Glad it's coming along! And also maybe search some of Bruce's posts, I thought he said he moved his case forward or something. And hope this rain today isn't messing you up! I'll try and do a search for you if I can.

    vertical DB

    When i installed my new vertical DB-case in 2013, i moved it approximately 6" aft of the bulkhead. My B24 is glass/foam, which might be different than the standard wood version. If it matters any, i added several inches to the height, basically even to the bunks.

    You may need to cut a hole in your cabin top as well.

    I was thinking about your boat the other day, doing the usual pouring through threads.What did you ever do with your floats connection, and did you end up dropping rear of floats a little bit, and if so what's been the effect. My other thought was that so far I like the widened deck treatment on your boat the best so far, little wider for more footing and the firm ledge to walk on. Far as I see the only real effect is the higher deck to cabin connection makes a change in window shape.

    Hi Barry,
    Unfortunately, I have been spending more time thinking about selling my Bucc than sailing it as my family has grown, and "my time" is nill. But! a sudden change of plans from the commodore has me thinking I will launch the boat in a couple weeks. Lovely change.

    Re Floats: I had angle Al welded on to the beams. I will bolt through the deck to a backing plate below. Shims can be added to raise or lower the pitch of the floats.

    Re water stays: I had beefy 'eyes' welded to the beams for the water stays. I replaced my flat bar water stays with short lengths of SS wire, and will use lashings instead of turnbuckles. The only reason I am using SS wire is for abrasion, we have a pile of lobster buoys that occasionally get hung up on the stays.

    I do like the wide deck. I think on my glass/foam boat there is minimal weight penalty, but you gain considerable footing, and the spray over the bow is a non-issue. I have only noticed wave slap once.

    When I get everything back together I will post more pics.

    Best,
    Carl

    progress report

    Things are going really well!

    I got the new case in yesterday. I decided not to do the standoff 3 piece bolt thing. Too complicated. So instead I built a second ring of 1-1/4" around the case. screwed it down into the keelson and bolted through that.

    been building at yard under the boat, hanging tarps from the amas to make a little tent. Advantages of multihulls!

    I faired the case off today and fiberglassed over both, looks good! heres some pics from the process.

    Headharbor your boat looks rad!
