Will Varnish cover small air bubbles in Epoxy?

Just putting the finishing touches on my Poweryak. I have some small air bubbles on the surface of some components after I sand very smooth. Will the Varnish fill the pin holes and make them visually dissappear?? Would thinning the first few coats help penetrate into the small holes. I will be spray...

I have built a Poweryak. I have an Electric Trolling Motor installed with 50 lbs of thrust. I am going down the road of beefing up the drive system. My design will have an Outboard mounted where the ETM is with the ability to be tipped up for transport as well as beaching. The deck covering on the o...

I am trying to stay away from Electric motors. I find for the money spent gas has much more going for it. Reliability for repairs, dependability due to its simplicity.

Anybody ever put an outboard in a Poweryak?

I have finally completed the Poweryak. I have come to the conclusion that our New England windy conditions are no place for the high freeboard, low keel and weak thrust of a 55lb Electric trolling motor on the Poweryak. Has anybody ever placed a 15 HP outboard inside the poweryak, similar to an inbo...

Okuome delaminated, remove or Epoxy repair

I am making a Poweryak, 2/3 the way done. I transported it on a trailer and apparently the small mushroom anchor in the stern bounced hard a few times and delaminated the outer skin. The plywood is 6mm and it looks like I lost 1 layer of veneer after I sanded all of the loose stuff out. Question is ...

Black spots in fiberglass cloth spaces ??

Building a Poweryak over the past year and just noticed some black spots in the weave of the cloth that has been layed down and epoxied. Just one coat of Epoxy though. I have not done the fill coat yet. It has been one year since the original laying of the cloth. The spots look like mold, any clues?...

Bruce: Excellent advice. I wasn't thinking about the "rail" aspect of the turning radius reduction. Perhaps I will shorten the length of the keel strip, similar to a sail boat design?? Or I could add a hinged rudder to the end of the keel?? Any more ideas or input?? please keep it coming. I will add...

Is a Double keel on a kayak more stable?

I am 90% complete with my Poweryak. We have a 150 lb dog that does not understand "Stay still" and need to make the boat more stable. Would adding a double keel reduce the port to starboard rocking?? I would be making the keels removable and out of thin Stainless Steel strips. The poweryak is 17' lo...

I am 90% complete with the Poweryak. It has much of the features that you request. Take a look. The plans from Glen-L make a perfect boat. The instructions could be a little clearer. They leave out some FYI items that I would have added. But, I am a detail oriented engineer. In the end, the items di...

I am using the Glen-L Poxyshield. I can not find the full cure time anywhere for the "slow" hardener. The fast says 3 to 4 days, ouch, thats a long time.

How soon after Epoxy Sheathing can you get er wet?

Building the Poweryak in the final stages. We are heading out on the water in 5 days. How long do I have to wait after placing the fiberglass outer sheathing on before I can get her wet. Temporarily of course. After vacation I will haul her back home and finish the detailing and Varnish as applicabl...

A great way to apply nice and clean fillets is to use a pastry bag from wifeys kitchen. Of course she can't have the bag back. It lays a very clean uniform fillet down in some tight corners

"Bill" can you explain why so I can present the facts to the supplier?? "razopp" seems to think it is reasonable. I would think there are standards for measuring "bdft". I was always under the impression it was "net" thickness or what you received. My board foot price was $8.80. As you can tell I do...

Board foot, Did I get screwed??

Hello: great forum, thanks for all of the advise. I am building my first boat. The Poweryak. Picked up the Mahogany last night. My questions are How is board feet calculated. All of the stock is 4 quarter finished to 3/4" thickness. 14' x 8.5" and 41' x 7" = just under 26 board feet. My invoice says...

I have purchased everything from Glen-L. They supplied me with the Poxy shield. The viscosity as mixed at 5:1 appears similar to an Oil base paint. I have an electronic scale so my ratios are quite exact. I guess that is the Engineer in me. Thanks for the quick reply
