Re: Small trailer re do

Not sure why to isolate Matt? Zinc is pretty close to aluminum on the galvanic scale- and usually corrodes first! That's why we use it on the hull - to protect aluminum. That said, zinc chromate primer paint? thin sheets of plastic film? some bottom paint? I'd say corrosion would be as low a rate as...

Re: Shrink wrap concerns

Mac, if the wrap will see wind- then it tends to shift, flutter a bit and 'shine' the sheer/rub rail where the plastic turns down over the rail. We usually see a shrink job, with straps under the bottom, where the plastic ends just below the sheer-rub rail. That is where we see some wind effect if t...

Re: Custom 26' Bell Craft

Sdenison, Just a general question about the paint work? it appears from some of the construction images that a zinc chromate primer may have been used as a bonding agent for the paint primer? I'm referring to the pea green paint images. Just a question about prep? Was the entire boat, at the metal w...

Re: 250's or 300's???

t;Trout, I'm not suggesting the hull's pitch, roll, or yaw will be different in a given sea- the shape and size and displacement will remain the influences there. The hull's movements will be more easily overcome by power when the higher power ratio is used. Like the difference between the extreme e...

tTrout, another location for tanks that works fine, but isn't as commonly used - is under the gunwales along the topsides, above deck. These tanks can be 20-30 gal each and easily locating 4 tanks helps with roll, if they're full, adds to a use of under the guard deck/sheer clamp/walk around deck sp...

In D'ship Pro there is a plate/panel/surface utility that shows areas of high strain/"un-developability" (areas that require more shaping than a flat surface without deformation) which is a colo...

G&R, I do understand that 5200 might not hold well in the bow stem area where there's some possible pressure or wash but.... I'd say it was the 'stickiest' and most flexible for small holes aft on the running surface? There, is no pressure there- at least not impact or bow wash. So small holes shoul...

About the existing holes, what would be the suggestion for plugging these? expoxy? durafix soldering? The holes shown in the bottom of the V, rolled into the bottom panel/hull sheet of the boat could be fixed/repaired in a couple of ways. First; If you can clean the metal around the holes so there ...

Re: Fixing severe pitting and holes on alu boat

This post is a speculation about the photo of the interior bilge corrosion shown in the OP.
