Re: New to Board need some help

norfbay, Welcome to the AAB.com Forum.  I don't know a great deal about riveted hulls- only those I've repaired for 30-40 years but almost always welding near or on a riveted seam with a strip of elastomer as sealant made the problem worse. On the other hand rigid epoxy like castings probably will ...

34' Multi-angle Deadrise: PaPaJ Launched

Some years ago I posted, during a conversation here, about the concept of having more than one deadrise angle in the bottom of a planing boat.  I haven't found that post- had some images in it and a brief discussion of why I thought this concept would be worthwhile to build. A long time friend deci...

Re: Is this corrosion serious?

Doback, Welcome to the AAB.com Forum. Serious corrosion usually described pitting of some level.  Since you don't show pitting and you can wipe the white corrosion sites off the surface with a fingernail?  Then I wouldn't call it serious. From the photo you can see the hull wasn't etched of mill sca...

Re: Etched hull

Spark, usually acid is sprayed onto a hull from the bottom up - so the foam has already lifted scale and contaminants lower down - then when foaming acid above flows down; there are no streaks.  This method seems to be the most reliable in terms of a uniform coloration (whitish or dull silver gray)....

Re: Marinette cruiser hull extension

Mike, I'm glad I wasn't being seen as rude and that as a designer you already know that centerline of pipe is as key to pipe layout as the keel plane of a boat!  Everything depends on an accurately drawn or designed centerline to run pipe (I used to do pipe design for oil and gas offshore here in th...

Re: Marinette cruiser hull extension

Msmithabr, I'm not lecturing, just noting that we'll need to have common terminology in order to share information about your hull and the proposed conversion to articulated surface drive from the keel boat she was designed to be. The hull lines (of any hull) are very specific and need to be underst...

Re: Marinette cruiser hull extension

msmithabr, I've extended quite a few hulls of this rough size, but all were welded hull's (or plastic hull add-ons) and this one appears to be (at least) partially riveted?  Don't know that for sure as the pics aren't zoomed in on the surfaces of the hull all that closely?

Re: Squished Gregor - Last Rites?

richas, if you drill out (the rivets) and separate the gunwale extrusions from the topsides sheet metal (?) they'll bend in very different manners. Therefore if any recovery is going to happen, you might try separating the two pieces then pressing or hammering the topsides into so reasonable pre-cru...

Re: Strange discoloration on aluminium hull

tonish123, this remark is based on the 3rd photo which appears to be 'vertical up'? that is; taken from the ground under the hull looking upward? From this photo I'd say the boat was formerly on bunks on the trailer instead of rollers that appear in the current photos- and I'm basing that guess on t...

Re: What Type Of Corrosion?

Is there anyway that this could happen   That's kind of hard to answer Hunter24.  Speculating about corrosion on a few photos is sort of low quality information (as a reply). Since you know that once the internal foam is potentially involved you also know that you have to pull the deck and confirm ...

Re: Mill Scale

TinCup yes, that does look like flowering on un-etched surfaces and acid etching will sure knock down what's there and prevent it happening more deeply or causing damage. Could be said of any part of a welded aluminum boat.  Spraying overhead isn't the most pleasant work- full oil skins and full PPE...

Rock'62, Portable TIG is somewhat compromised over shop TIG due to the power supply requirements and the most common solutions to that equation.  I'd spend most of my time, were I in your shoes, working to get the skiff seen by a shop, in their own facility.   You can save yourself some of the costs...
