    Im just trying to get advice and make sure the plan I have is good to go before I order my materials.

    I will be using Epoxy resin, is two layers of 17oz biaxial on the stringers with a layer of 6oz "S" glass on top good enough?

    Also..
    can I just use the 17oz biaxial or do I need to alternate layers of different glass when fixing cracks and filling gauge holes?


    Thanks in advance for any tips or advice.

    where is your crack/s ? check out my thread (turbo wogs project) in jet boats. i might have enough info for you. i did wrap one stringer in good shape with 2 layers of nitex.(matt on bottom & weave on top) & called it good . but i did have a crack & ground it out realy good from the bottom & did alot of glassing. pm me if i don't get back here . i am definaltely not a pro but you can see what i did. holes i ground out really wide & all the way to the wood & drilled out larger till wood was clean ,not rotted ,then elmers exterior glued. cut wood dowels a little long ( buy all sizes, make it tight going in) grind dowels flush then glass, over layer then sand down. reglass if not flush. when all holes are done ,wrap the stringer 2 coats of nitex. that is what i was told to do & i did. as for the crack ? where ?pics ? don't bother doing it if your not gonna go ape sh*t on the cracks & get in there deep. my hull was cracked when i bought it & i paid two times for the repair & re-cracked. then a friend helped me.......cracked again. then i ripped the f''er to the wood from the bottom . still holding together & hit some rough stuff so far. 1 gallon doesn't go far on a big project. i kept running out . i finally bought 5 gallons of vinyl ester from "composite one" for low $100's .composite one was recomended to me from outlaw boats,so was the vinyl ester

    Sorry I should have been a little more specific I will be replacing the stringers. I have already cut them out and was just wondering if 2 layers of 17oz biaxial with a layer of 6oz S glass is good enough when putting the new ones in.

    And the crack is in the corner of the transom I have ground it out almost all the way through and I will be fixing the inside then doing the same thing for the outside. I am just wondering if I can layer the 17oz biaxial to build it back up or if I have to alternate it with another type of glass.

    Thanks

    RBC , the 1700 bi ax will work well , and will fill all the needs in any phase of your project and two layers of 17 oz , and one layer of 6 oz finish fabric will be more then enough material although i normally go with three layers of 17 oz & 1 layer of 6 oz ( for stringers) which on my end may be a little overkill ( beef ) which is something i have done for years and a very old habit that is hard to break but non the less you will be just fine and if i was you i would make ply plugs to fill in the old gauge holes filling in the perimeter of the plug with a thickened putty made from cabosil & resin ( peanut consistency ) grinding a bevel on the edges or perimeter of the plug & hole itself glassing in both sides .

    RBC ,just a quick mention , and that is i think you will find using the 6 oz S glass , finish fabric , chesse cloth , surfboard fabric , will leave a very nice smooth , and clean looking layup that is very pleasing to the eye .
