    Hello all, I'm considering plans for a Carolina style sport fishing boat. It has nearly everything I'm looking for, except there is a small cabin forward (v berth and a head with headroom for sitting on the berth) that I would like to make a little larger, height wise. On the drawings, the sheer is continuous from bow to stern. I was thinking of maybe sweeping it up as you move forward and raising the foredeck some (I've seen this on a bunch of "Carolina" style production boats). Is this something I can just "do" by adapting the plans myself, possibly using a software program, or is this something that I really need to have looked at by a professional designer. While all of these changes are above the waterline, I guess I'm concerned about the addition weight this might add. Thanks for any help you can offer.

    If the designer is still living you could discuss your ideas with him/her. If not, making the cabin taller sounds a lot easier to me than messing with the sheer and possibly tampering with the appearance of the boat. I don't mean to imply that the taller cabin won't change the apperance any, it just won't harm the shape of a nicely designed hull.

    Pericles, thanks for the links. Actually, the CX25 link will maybe help explain what I want to do a little better. The plans I'm considering are for a Carolina Angler 31 on the Glen-L site (it's a Ken Hankinson design and apparently they just bought his plans and web domain)

    https://www.boatdesigns.com/products.asp?dept=729

    What I'd like to do is make the bow of the CA31 look a little more like the CX25. On the bateau web site there is a non-cabin version of the CX25

    http://www.bateau.com/studyplans/CS25_study.htm?prod=CS25#options

    If you scroll down to the options for that boat, there is a jump cabin option. That's what I want to do with the CA31. Is this something I can easily do to the CA31?

    Thanks again

    nhmtnbkr,

    That Carolina Angler is a smart looking boat. You can increase the flare by reshaping the temporary forward bulkhead frames, so that the slitted ply fingers splay apart a little more, before fastening to the frames on the jig.
    See the study plans for the LB26. http://www.bateau.com/studyplans/LB26_study.htm?prod=LB26

    That's the first part of the hull shape created. Then, diagonally cold mould two layers of marine ply to finalise the shape like this. http://powerandmotoryacht.com/boat-tests/jarrett-bay/2005-jarrett-bay-32/gallery.aspx

    For further help you should purchase this book. https://www.boatdesigns.com/prodinfo.asp?number=12-447 and read all the how to tutorials here. http://bateau2.com/content/category/5/78/28/

    Everything is possible.

    Best of luck,

    Pericles

    Can't see just how much flare there is but it seems like quite a bit. That means that raising the forward sheer would really cause problems with beam of the deck up near the bow. Berth space on this kind of boat is never meant to be more than a hidey hole in bad weather. Fishermen are supposed to be tough. You might be better off with another design that offers what you want. The Bateau design with the belt might be better for you. Changing the sheer is not as simple as it might look on 2D paper, especially with a lot of flare.

    I am a builder of Custom Carolina boats.and I do not want to be the one to point it out but none of the boats listed in this post are true Carolina Boats. If you are interested in a true Carolina boat I have one for sale It is a 36' Express that is under cont.in my shop.the boat is all framed up and ready for planking. I am asking $10,000 for the boat and the materiel to complete the planking. I will also throw in two full rolls of fiberglass and the epoxy. contact me at the email below.
