Maritime Skiff Casting Platform Replacement and New Pilot House

Hi Everyone,

I am doing a small repair on my skiff. I am replacing a casting platform that was made out of plywood and adhered to the hull with 5200. I tore out the old platform made a new one out of 3/4 encapsulated foam core panel. The bulkhead is made out of 3/4 marine ply encapsulated in glass. I am using vinylester resin, cloth tape and mat to tab the platform to the hull. Can I use epoxy to adhere the bottom of the platform to the hull and to the plywood bulkhead and to also make fillets? Or is there a more suitable product that I can use. I am also going to be adding bulkhead type rod holders to the sides of the hull. I plan on epoxying a 3/4 piece of plywood to the hull and then trough bolting to the outside of the hull and thoughts on that idea?

Thanks.

cloth vs mat

I would not use cloth tape I would use matt cloth is not strong enough mat would be a much stronger bond just my $0.02 but everything else sounded good and the pic look like nice job........

You've got some grinding to do to that hull. I'd install to vertical piece first - fully floating on polyester auto body putty. Make your fillets with the body putty and then glass both sides. I'd make the platform top from some cheap stock and then cut the bulk of the center out leaving a piece that look s like a fingernail clipping except that it has a uniform width of about 6". I'd then treat the under surface with wax, PVA release, wax paper or some other agent that will ensure that you can remove this later after the resin cures. You want to use this to create a flange around the entire perimeter of your platform. Once the resin cures, pull out the temporary mold, lay down a bead of 5200 and fit the finish platform deck. Again, use the auto body putty to create a fillet; let it cure and then glass it in place. I don't think epoxy has anyplace in this project and I don't much care for using an ester resin over epoxy.

Thanks for the replies gentlemen. This is my first time working with fiberglass and so far so good. Joe from Merton's has been a great help.

I thought about making a flange as well. Would you put the template up against the hull to make a lip or just make it on the template and curve it up when you wet it out?
I already have a template made out of osb, and i do have some peel ply.

I am planning on installing the vertical piece first and the grinding starts tomorrow.

Thanks Again!

My suggestion is both strong and very easy on one with limited f/g skills. Take it easy on the grinding as you want to just go through the resin and expose glass fibers in the area that you'll be glassing to. Good luck.

The First project went well, so now I decided to build a pilot house. I will be using foam core panels again but my question is how many layers of mat would you use per side on the core. I was told two, but I don't know if it is going to be enough to give it the strength I am looking for. Any suggestions would be great.

Started the house! Just have to wait for the weather to break to get it installed on the hull and finish putting it together.

Hello, Is that an 18' Maritime? I have the same boat - mine needs a new deck, it has some delamination...... The older boats have plywood decks with glass overlay, but the transoms are all composite. The new ones are completely composite. One thing, watch the weight of the new pilothouse, you don't want to lose the self bailing aspects of the boat. (I am sure you already considered this, but just in case). Looking good so far. I will be doing the deck and a full resto on mine, will post it up here when we get into it. What kind of power you have on her?

 

[Med Sun]

The house is pretty light it is all composite except for the console portion. I am offsetting the weight by putting in a slighlty larger fuel tank in front of the house. The skiff is a 20 footer. I am thinking of putting a bilge pump set up that I saw on another maritime just because at times when you are fishing you get some water in the back.

Finally got her done, windows are in, just have to add the steering and controls and electronics.

Nice work MEDSUN looks great
