    What to use for drain tubes?

    I have three drains in the transom; splash well, deck, and bilge under deck. When the transom goes back in, what do I use as drain tubes? Originally the boat used brass (?) tubes in the deck and bilge. The splash well used a plastic tube. Where can I find replacements?

    Removable fishing deck design

    Here is a picture of the bow area of my tri hull. If you fish this area of the boat you have to stand in the narrow area between the bow seat boxes. My 70 year old father likes to ride up front. I would like to make a removable deck for this area for him to fish on. It will also need a...

    Grinding with a belt sander

    I am looking to speed up the grinding to prep a hull for new glass. I have allot to do. I have been using a 4 1/2" grinder and flapper discs but it is kind of slow. I have a larger grinder, 6" i think, but it hate using it. Has anyone tried a belt sander? I do not want to invest in one if it is...

    Epoxy to laminate cores Poly to cover?

    I need to build my longitudinal stringers and my transom by gluing two layers of ply together to get the proper thickness. The transom will be two sheets of ply glued together then glassed into the fiberglass hull. My main center stringer is 12 feet long. I will need to scarf and laminate two...

    Transom core Overkill?

    I am finally getting some supplies together to put my little tri-hull back together. I have my resin. The glass is on the way and the wood for the transom and the stringers. A question about my transom came to mind. The original transom was built using a single 3/4" piece of plywood. The upper...

    Timber lumber

    My little tri-hull project has three main stringers under the deck. The center stringer along the keel runs the full length from bow stern. (about 12 ft. long) It is a single piece of lumber that was shaped and glassed into the hull. Originally I intended to replace the center stringer using...

    Epoxy And CSM?

    I heard somewhere that chop strand mat cannot be used with epoxy resin due to the binder used to produce CSM. I have a tight turn I need to lay up. Is this true? If I cannot use CSM what should I use for my repair? I need to repair an outside corner.

    Paint or Gelcoat on trailered Boat?

    It time to make some decisions about the finish I am going to put on the bottom of my tri-hull. It is flipping time and I need to make some repairs to the bottom. Originally I intended to paint. I have since become paranoid.:eek: I am concerned about the durability of the paint on a bunk...

    Which is the best resin roller?

    I know I need a resin roller to remove bubbles from the layup while it is wet. Which type (or kind) of roller works best for general layup projects? (grooved, un-grooved, length, plastic, metal?) Are the handles made to accept a paint stick or a screw in handle? I may need to get to an area from...

    What weight fiberglass do I need?

    Can anyone recommend what weight fiberglass roving and mat I am going to need for the transom and stringers of a 16' tri-hull? I was thinking 1.5 ounce mat and 18 ounce roving. But that is a total guess.

    Stringer contact and Hard spots

    OK, explain to me again how bedding stringers in peanut butter is different from bonding stringers to the hull? Seems to me it is the same thing....just thicker glue. Shouldn't the stringers be sitting on something more pliable to prevent hard contact? Ok, disregard this. I found an excellent...

    Great info on resin and glass selection

    My tri-hull transom replacement w/ pics

    Ok folks I am joining the ranks of the unfortunate. The tri-hull needs a transom and here's how it goes so far. After getting over the shock and dismay of realizing the transom finally had to go I started by de-rigging. The engine was first to come off. She's old, but she's a runner. Next I...

    Controlling Shrinkage

    I have to replace the transom on my tri-hull. :mad: I plan to remove the cap and possibly the inner skin of the transom to access to old core. I plan to replace the old wood with new marine ply and replace the inner skin. I may either totally reglass the inner skin or glass the old skin back in...

    Stress cracks vs. gel coat spiders

    Here is a good example of stress cracks in gel coat in the first pic. This is a corner at the splashwell of my transom. Notice how the major lines parallel? When ground into, I will find the cracking probably extends into the laminate underneath the gel coat. If you look closely in the next pic...

    A home build stand that works

    I built this outboard stand from some plans I got online. I can't remember where. (in here maybe) The design was done by D. Hayes Jr. I made it a bit larger than the plan called for and added a shelf. It is a good design if you are looking for one. The pics make the base look as if it is...

    Transom Repair- Capping vs. skinning

    OK folks its time to revisit the rotten transom repair subject. I have to replace the transom of my tri-hull. If I were opting for a complete restore of this boat I would remove the cap and cut the floor out, replace all the wood cores and coat everything. This is not that situation. The floor...

    Engine lift details w/ pics

    I finally got it done! I have been working towards this for a long time. Finally things came together. Here is how things went. First I set the gantry to height. It is a scary 12 feet from the ground to the beam! After removing the canopy, un-bolting everything and rigging the leveler and chain...

    Stringer Pre-prep

    After a thorough cleaning, I need to start removing the cores of the stringers in my old tug. They are 40 years old and look to consist of wooden cores covered in heavy roving. I intend to cap the stringers, remove the cores and re-core them. Hopefully I will do this by re-coring the fiberglass...
