A Fiberglass Fix for the Foredeck

Andy Miller is back on the foredeck of his Bertram Moppie that is in the midst of it’s second (or more) restoration. Andy is an expert and he knows enough to have doubts about the structural integrity of the deck surrounding the forward hatch. The best repair is one that will last for the rest of this classic boat’s life, and Andy counts on a few layers of 1708 biaxial mat fiberglass to make sure the deck is rock solid. Using our TotalBoat Laminating Polyester Resin, Andy lays a nice, thick coat on the prepared deck and lets the 1708 soak it up, using a squeegee to move the resin around underneath and make certain that every inch of the glass is saturated. To Andy’s surprise, this method has really beefed up the foredeck and his next layer can now be some TotalBoat gelcoat which will help the Polyresin cure properly.  Check out Andy’s progress in today’s video of the week! 


We don’t attribute Andy’s success on this foredeck job to “dumb luck.” Andy’s experience allows him to think fast and make appropriate adjustments when he’s ordered the wrong gelcoat (needed wax in it so it would cure and so the Polyresin would cure…).  His near mistake points out that preparation is key before you start your project – having all the right materials and tools and knowing your process will help to ensure a perfect result.   If you’re not sure what you need to succeed with your project, the TotalBoat Tech team is available to advise you on the proper processes and products to help you get the job done right. Call us Monday-Friday at 800-497-0010 and we will do our best to help you be successful!  Thanks for watching.

  1. Thank you for making these boat repairs they are helping finding some of the products we don’t think of. I watched you reglass fordeck. Great job. I’d love to see some cures for bottom blistering.

  2. Andy, thanks for the video. Good stuff, especially curing the gelcoat. Questions:
    – How do you remove the wax?
    -Did you fair out the glass layup before applying gelcoat?
    – What is 1708?
    – What is the deck core and what is its condition…past deck/hatch leaks?

  3. I cannot wait to see you do the faring and finishing. Those are my big issues I cannot ever get a great finish it is always VERY strong but does not look like a new boat. I am currently working on a 78 mako hull that we ripped the entire deck out and replaced with coosa board and put 4 layers of that same 1708 fiber glass and on the deck where we will deck paint and non skid not that big a deal but the sides I can never get them the way I want them to look. By the way love your idea of using the large roller for putting down the resin. Boating is my hobby and I love to work on them.

  4. Andy,
    Have you seen or know about this product?
    It says it can have all underdeck compartments flow water plus add aeration too the bilge. No mechanical devices. All gravity.
    Interesting system
    This is used in conjunction with expanding foam.

  5. Definitely a “10” with the thumbs up! This gave me the tools / info I need to help re-enforce the hull on our 1971 YarCraft Yankee, which also had original “chop gun” installed fiberglass.

  6. What a great job. The Video was well narrated.
    The host of the video did a great job with the camera. I have done business with James town for years, this new avenue they have taken is a very smart move.
    I am quite sure it will set them apart from Kellogg/Land & Sea and the rest of the pack.
    Please keep me post on any new videos.

    All The Best

  7. I love watching Andy’ videos, as well as Lou’s Tips from a Shipwright, on youtube. The very fact y’all have a connection with them, possibly sponsoring them, has led me to shop Total Boat products and Jamestown Distributors even more. As an amateur boat builder/tinkerer, I have found these two guys a wealth of information, and seeing them use Jamestown product helped cement my decision to shop here. Y’all are now my go to, well, only fiberglass and fiberglass suppliers.

  8. Andy, you had the video speeded up, my question is about how long did it take for you to lay the mat and resin down. At about 2:08 you said you were adding a catalyst, 12 cc of “met” per batch of resin, how much longer working time did this give you?

  9. Hi Anthony here! I my self ReBuilt my Bertram Baron 1969 (28′ ) Baron, in 1987 thru 1990 (3.6 yrs.) and at that time the Unidricetnal just came out, and After she was totaly done I Tuned the Bottom, She was a Very Stout Boat Strong but Light. From the Shoe of the Keel to the Stringers Transom,Then added Mini Ribbs under the engines So the Strings would not sl;ip down the inner bottom, Then To TEST, Took Her Out and Let Her Run, Went around Point Bonnita In San Francisco out the G/G Bridge, 6′ Ters 40mph Then Back to Home port San Rafael Ca. Hauled the Boat and Did a Complete Inspection crawled thru the Hull PERFECT Great Job ! Anthony.

      1. Also, this is the first I ever heard that you could put mold release on top of resin for the same effect as wax in the resin. You applied it after the gel coat had cured?
