Re: First-time build Questions and thoughts

fullmetal, my remarks are focused on the idea of building "small" as a warm up to building "larger". I will say skiff sizes are as follows; 10-14' long (?) being small, mid-size being 14' to 18', and larger skiffs being longer than 18'- maybe beginning at 20' and larger? I'm trying to make some defi...

Re: Pacific V2325 vs V2600

creme'b, some remarks on the post, but not necessarily useful replies? is the ride in the 26ft hull going to be that dramatically better in small to medium chop than the 23ft hull? sorry to report the obvious problem or relativity. Dramatically better is not a quantifiable value. What does the "dram...

Re: Feedback needed on a chambered boat design

alumioforte, I'm an old marine traditionalist- so segmented hull forms are not appealing to me. The mitered sections of a press braked hull sponson is so unappealing to me that I term his entire effort "agricultural" and I mean it as a disparaging term. "If it floats it should flow"; the shape of bo...

Re: Quintrex repower? Any Aussies out there?

Will I get more speed with a doubling of HP or will the added 50lbs of motor weight cancel that out.? no you'll get more speed, but not double.... the 50lbs is well within your bait tank/well high to low so not going to make the difference to cancel the added horse/push power. Not expecting a doubl...

Re: Quintrex repower? Any Aussies out there?

Livliner, first to address a bit of "adspeak" in the misnaming of the shape of the skiff you show- that's not a dory! I know that lots of people use different terms in different locations and worse ; the manufacturers use a host of miss-used terms about boats..... but that's a roll formed skiff. It'...

yes, Krisinak, I have made more mistakes in welded aluminum boat building that the average guy since 1977 when I started building, and I have seen many fastener issues, so I "am experienced". But overall, I've seen SS gall to itself, calk up, twist off, elongate and lose torque.... and corrode the a...

Re: Cracked Trailer frame repair ideas

Tfitz, my only question is about the new liner 4" channels- did they bolt in above the repair welds- or did you have to round the outside of their web to flange corner to allow for the increased curvature of the repair welds? Not that is makes super critical difference, just curious? I'd have left t...

Re: Electrolysis

funny that you think hot dipped with zinc coating - the former "only material" used in anodes! is not acceptable for aluminum work! Why could it be used as an anode for the last 70 years? Since the Galvanic differences are about as minimal as found between any two metals? http://roofhelp.com/galvani...

Re: Electrolysis

Krisinak, generally aluminum threads- of almost all types are unreliable. I'd say that only the most rare mechanical circumstances justify aluminum thread fasteners- my experience with them has shown them to be Fragile, at best. IF you torque an aluminum bolt- it will elongate and tear at a point in...

Re: Electrolysis

Krisinak, Challenge, Chaps, another item that has come up in my recent inspection of a really new, name builders' very costly boat is the way the 'zincs' are mounted to the hull. Many believe- and I think they are in error(?) that bolting on anodes (regardless of alloy) with SS bolts is the "best pr...

That may be worth a try on the outside between the motor and the transom It won't work on the inside though as the transom is hollow and if the outside leaked it would simply fill the hull with water.

Re: 250 outboard install

tim, lots of fallacies in the idea that wood will isolate the engine! the bolts will provide a path to the hull of low if not very low resistance! So the wood may act to insulate some of the mount- that wood will be 'shorted' by the bolts! Wood is a poor choice- why is the wood suggested? Why a pad?...
