    Before I start this thread I would like to add a list of common acronyms and terminology for doing boat fibreglass work and repairs, you will see them used ocassionly throughout this build... Thank you

    Fibreglass Defined

    CSM =(also known as chopped strand mat and fiberglass mat) has short strands of fibers held together with a resin binder. The fibers are randomly oriented. Mat is only compatible with polyester and vinyl ester resin. When resin is added to the mat, the binder dissolves and the fibers can be moved around. It is easier to conform mat to tight curves and corners than it is with weaved fabric and is made up of 25-50MM long fiberglass strands.

    Binder = typically styrene-soluble that acts like glue connecting the fibers. The binder is designed to dissolve upon contact with styrene in polyester resin or vinylester resin.

    Fibreglass = Chopped strand mat or CSM is a form of reinforcement used in fiberglass. It consists of glass fibers laid randomly across each other and held together by a binder. ... Because the binder dissolves in resin, the material easily conforms to different shapes when wetted out.

    Fillet = A fillet is a continuous bead of thickened epoxy or polyester mixture applied to the angle created between two parts. It increases the surface area of the bond and serves as a structural adhesive and brace.

    Tabbing = Typical construction (called "tabbing") involves bonding stringers and bulkheads to the hull with strips of fiberglass cloth wetted with polyester resin. Done correctly, these tabs give an initially strong connection that seems permanent

    OZ = For example, if an application requires 3 square yards of a 4 ounce-per-square-yard fabric (total fabric weight is 12 ounces), 12 ounces of resin will be needed. However, if 3 yards of 10 ounce-per-square-yard fabric is chosen (total fabric weight is 30 ounces), 30 ounces of resin will be needed.

    1708 = 1708 indicates the weight of each layer. The biaxial weave cloth is 17 oz. per square yard, and the chop strand mat backing is 8 oz per square yard. Total of 25 oz is required per yard of 1708, 17 for the biaxial weave cloth + 8 for the chop strand mat.

    Schedule = This is a list of the individual layers and orientation of the plies

    Boat Structure Terms

    Stringers = Stringers are support members bonded into boat hulls, usually oriented parallel to the long axis of a boat hull.

    Keelson = a longitudinal structure running above and fastened to the keel of a ship in order to stiffen and strengthen its framework.

    Bulkhead = A bulkhead is an upright wall within the hull of a ship, other kinds of partition elements within a ship are decks and deckheads.

    Transom = A transom is the flat part which forms the stern of a square ended boat.

    Hey to all, I just wanted to post an update to the 1977 23' Hourston that I started this week, I know its just another build thread but thought a few may be interested...

    I had 3 layers of 3/4" plywood to demo from transom and yes it was quite rotten :eek:

    So i'm told this boat was redone a number of years ago, if in fact this was done correctly it should have lasted another 30-40 years before any repairs would be needed. Buyers beware, just because someone tells you the the stringers, transom and deck had been redone, don't be so fast to consider it bonus. This boat was a mess, it literally had ants crawling out of the rotten wood, LOL

    Below is a before and after I sanded and cleaned up the starboard corner...

    Nice work. Your moving along on cleaning the transom area quickly!

    Have you done this before?

    I found the grinding of the fibreglass to be the worst part of the project.

    Thank you - I haven't really done much fibreglassing, I am grinding double the material as the person who, so called "redone" this boat looks like he literally poured resin in the bottom, bilge area. It is definitely resin rich! Haha :)

    ... and this is what I'm talking about! layer after layer, see how flakey the edges of the cloth/resin is? If I were to not do any prep and just layer over what was there it could potentially be catastrophic and cause failure, also see how thick the resin layers are without any cloth... UNBELIEVABLE! :eek::mad:

    Hey 23Hourston, the keel on this boat seems to be perfect, i need to expose a bit more but so far, all good! I'll post a pic in the next few days...

    O and yes on the orange, I love it but my better half would like to change, not sure how it will play out, LOL, this is the only 23 orange I have seen to date...

    Looking good. Tuff work. Especially with all that extra from the last person... I'm curious as to whether you'll be using epoxy resin or polyresin

    Hey 23Hourston, I will be using a combination of both, I will either document and/or video the process...

    Thank you bigbruce, I plan on using a bit of coosa on other areas, but for me, plywood will be the ticket for mounting the pod...
