I was planning a stitch and glue boat myself but, considering the bargain prices for second-hand sailboats where I live, I picked up a nice old girl when it came time. My brother, on the other hand, built his houseboat from marine ply and epoxy.

He didn't bother with the WEST system. I think any epoxy will do these days, and you'll save plenty. Really, it's just a chemical recipe and everyone knows the ingredients now, unlike 25 years ago.

I was looking for alternatives to West Systems locally but they seem to already mixed with a filler. I have used Pioneer and will probably use that for the joints but need raw expoxy for the taping and the cloth. Actually considering not doing the external fibreglass cloth and use plenty of expoxy primer instead!

The most expensive part of the build (other than the outboard motor) is the fibreglass cloth and the epoxy resin. The recommended resin is “West System” 105 and I will apparently need about 10 gallons! I have managed to track down a supplier in Mandaue but haven’t got the courage to enquire about the price as yet. I’m expecting upwards of USD$1,000.

I bought epoxy from Polymer Products, Mandaue....maybe that's who you've tried. I wasn't constructing from scratch, just stripping and restoring a banca with epoxy base coating and some repairs. It was about 5 years ago, but 2 gallons and a bag of filler (which I didn't use), and a gallon of reducer, and a couple of metres of cloth came to about 7000 peso. It did the job fine. Then epoxy paint. Boat's still good...used daily by a local fisherman. The epoxy was slow, a day to lose tackiness. but the odd insect mark etc didn't matter as its a working boat, not a shiny white wonder. They were nice people at Polymer.

If your quantities are well calculated, I think it's worth opening a can when you buy it. Someone else might advise here, but it seems that, and not just the Philippines, the "gallon"cans are sort of partially filled. maybe something to do with the nature of the components. And don't really make a full gallon volume when mixed.

Don"t forget the pharmacy for a box of surgical gloves!

Thanks for the info Trthebees, Polymer Products is exactly who I was going to contact so will look at the options after taking to them. 

This is a bit of a toe in the water project and if it goes ok them something a little bigger next time. One of the problems I have is lack of boat ramps in Northern Cebu so needing something I can manhandle from the beach.

Is there a specific reason why most are using epoxy instead of polyester or vinylester in the Philippines? Is epoxy easier to find or what? Vinylester should be also a good option if you're using fiberglass. Even polyester should be enough if you use a good topcoat.

In this area (Duma), epoxy is everywhere, the rest are nearly non existent and expensive.

Really dig that boat Larry, wish it was in the budget right now. Great design, pretty and seaworthy.

Update and photo’s on my build progress.

Because I didn’t have a suitable flat area I had to build the base frame to hold the bulkheads on a sloping area. Very important to get everything level and aligned at this stage.

I tracked down the Epoxy and fibreglass cloth at Polymer Products in Mandaue as one of the members suggested and they were very helpful. the epoxy is p2,100 per gallon and I got 2 gallons to get started. Also got the fibreglass cloth and tape which is not exactly the product that I wanted but as you know you need to improvise in the Philippines.

The scarf joining of the plywood panels was time consuming but seems to have worked out ok. each panel is made up from 2 full lengths & a 1/3 length of ply.

Was looking at Outboard Motor options and considering a second hand unit however a friend put me in contact with ALS Marine in Manila and they have brand new 25HP Yamaha four stroke for p147,750 which seems like a good deal to me. many of the second hand units I saw where not much less than that. The plans state that 30HP is recommended maximum.

I cut out, assembled and stitched all of the panels over the last week and it was fast and very straightforward. This is where all the time aligning the base frame & bulkheads pays off. lots of measuring and level checking but it all seems aligned and straight so time to begin the glueing process.

Costs so far:

9mm Marine Ply p9800

12mm Marine Ply p9600

Framing Timbers p3,800

Epoxy Resin (2 Gal) p4,200

Fiberglass tape and cloth p500

bolts, screws & misc p1,000

Plans p2,800

Total to date p31,700

I have not included the tools, circular saw & jigsaw that I purchased because I needed them anyway and will use them on other projects.
