Re: What Type Of Corrosion?

Hunter, I'd guess this was crevice corrosion where water could enter the paint film edge at the rivet perimeter and by capillary action fill the tiny void where the paint didn't seal the rivet edge to the sheet? This small but common void is covered with a paint film but.... with hull use there is o...

Re: Help selecting boat for San Francisco bay

I’m looking for a deep V about 20 feet But... Then, in winter, I want to be able to put a blind on it to hunt the wetlands in San Francisco Bay so the draft can’t be too deep. Imhisnibbs, can't help but notice you're describing two separate boats?- Not a "multipurpose" boat- as there is no way to g...

Re: Fuel tank design / pick up tube

Boxboy, couple of remarks, hopefully of some help? First, unless a plastic draw tube (downcomer) is secured in some way? just a little slosh/wave/roll or the hull will allow the fuel to push it back and forth (side to side or fore and aft?) and then decouple at the fitting/top. So, if you're using t...

So while we've had a few riveted, super thin scantling skiffs before, not that much expertise in the riveted joints here- we tend to want to weld anything where metal touches metal. If the skiff w...

Re: Aluminum Anode - Please Help

pop, if the anode is to protect from stray current (as in flow of electrons !!) then "conductive contact" with the hull is probably a high priority order! Anodes should be mounted so there is no electrical insulation from the hull. Many builders bolt them on- but that connection can, and does, devel...

Re: Looking for a 17-20 foot boat design or manufactured boat that is a little unique

KJ20, not seen a C-dory design in welded aluminum but no reason the lines can't be taken off and a set of plans generated? Not very inexpensive process if not already a 'stock' design somewhere? The trunk cabin and fore deck of the C-dory do help to break up the too-tall cabin line, so does the shee...

Re: Looking for a 17-20 foot boat design or manufactured boat that is a little unique

KJ20, Welcome to the ABB.com Forum, here's a couple of remarks about the class of boat you're describing. First, that short a hull with a full standing cabin is not regularly designed by many designers because they're "homely as h*ll"! Here's why. A 17' to 20' LOA hull usually has sides that are les...

Re: 14 foot alumicraft

general, I think the USCG placard on your skiff puts the upper limit on HP for the hull's wt and load? So in general use 35hp would be pretty much more power than you'd use regularly unless you're in the racing frame of mind? Then I'd be more concerned keeping the bow down, not flying (!) with 35hp ...
