Re: Any Can-Yak Builders Out There?

OK--all four frames (we're building two boats) are glued up. First step in this exercise was to make masonite patterns so that the mahogany bits could be finished with a pattern-following router bit. This has exceeded my expectations. While there are some very minor issues related to paper stretch, ...

Any Can-Yak Builders Out There?

With our Zip pretty much down for the count due to lack of water in our local lake, I decided I needed another boat-building project while the lake (hopefully) fills back up this winter. I've always liked the looks of the Can-Yak, and bought the plans a few years ago. It should be a relatively quick...

Re: Structural role of gussets

Without gussets, you have a face joint that is relatively weak. Gussets distribute stresses in this area into shear loads that are distributed over a larger area. Cutting them back so that you have a sharp corner will create a stress riser in this area. Will it fail? Who knows, but if it were my boa...

Re: Brendons Zip Build

We had to shim the chines forward of Frame 5-1/2 on our Zip as well. We think that laminated the chine logs from two pieces caused them to lie a little flatter in this area, than they would have if we'd made them in one piece. It's not a big deal; just add more wood than you think you'll need, and p...

Re: Skeg vs. Fin

Mark I also thought of going with a fin but decided against. I'll have to take measurements of my current skeg setup to compare. My boat currently handles well under full power with no cavitation when making tight turns and is responsive on gradual turns also,you need to hang on for those high spee...

Skeg vs. Fin

While our Zip was under construction, we debated whether a skeg or fin would work best. The argument in favor of the skeg was that launching and retrieving would be easier, and it would allow beaching of the boat. While the hull was still inverted, I installed a 54"-long mahogany skeg, that tapered ...

Re: Motor mount holes

On our Zip I did what Garfield did--just drilled the holes oversized and sealed the wood with epoxy. No other sealants were used and I've never had any water come in. If water intrusion is a concern, you could probably just apply a blob of non-hardening caulk over the nuts on the inside of the trans...

Re: Mercury Mark 55 advice please

I paid $750 for our '56 Mark 55, with controls and some very tired cables included. The price was probably a little high, but I got it out of Kansas City, where salt water is as rare as unicorn f*rts--much better than the salty dogs we find here in southern California. If the motor is complete and h...

Re: Outboard Bolts

I used two stainless carriage bolts to secure our 1956 Mark 55 Merc (115 lbs) to the transom on our Zip. The square portion under the head indexes nicely with the motor mount, making it easy to tighten the nyloc nuts from inside and without a helper. Rounded heads just look better as well. I did dri...

Re: Working on old outboards

We've had good luck removing bolts from old outboards, using PB Blaster penetrant. Warm the affected area, apply the PB, and let it soak overnight. This stuff works much better than Liquid Wrench or any of the other penetrating oils.

Re: What is it like to pilot a Zip??

Our experiences with the Zip are pretty much like everyone else's. With a 40-horse Merc Mark 55, the boat gets on plane very quickly, and gives about 30--32 MPH with the right prop., which feels pretty quick in a small boat. With its minimal deadrise, it's at its best in protected water and you'll w...

Re: Zip Transom Advice

The Zip transom as designed is pretty strong. A percentage of the load imposed by the motor will be transferred to the keel batten via the transom knee while, as Jeff mentions, the motorwell will also stiffen things up. If you deck around the 'well, this will "close the box" and add even more stiffn...

Re: GERONIMO'S bottom planking

When we planked our Zip, we used some panhead wood screws in conjunction with some 2"X2" plywood blocks as cawls to prevent the screws from pulling through the planking. Since this was during the Santa Ana wind season (<10% humidity), we also kept the plywood wet while bending it into place. It's a ...

Re: Squirt transom help

The trouble with most exterior, or shop-grade, plywood is that it has voids in the inner plies. This can cause problems in highly-stressed components, such as the transom. When used for planking, you can run into all sorts of trouble when bending it into position, particularly if a void happens to l...

Re: Ski king build Tasmania, Australia.

Your build is looking nice, Tom. The Ski King is a really pretty boat, and a V-6 should be a nice choice for power. Being shorter than an inline four or V-8, you should be able to fit everything in there without having an excessive shaft angle. Wish I'd had your shop space when we built our Zip! -Ma...
