Re: 1995 Smoker Craft Pro-Alaskan 16 - Found some bad corrosion :(

Steve G, the photos show lots of pretty serious problems. And, absent some idea of a overall view of the boat- showing some indication of the extent and location of the rib failures? I'd say no one with real knowledge can offer you any assurance that the boat is sound enough to use "safely"; EVEN WI...

Re: Newbie introduction

bkfab, in touching on the bottom deadrise vs "performance" issue you'll end up getting to "ride" as a concept and I'll share some insight. This is a design helix issue. The design helix is a slowly spiraling upward circle of design decisions that becomes more and more detailed until the spiral ends ...

Re: Newbie introduction

Wantry, yes I'd intended to compare to ' way overbuilt ' equipment by referring to Specmar's as military grade. Their scantlings are thicker than needed - needed being a relative term. But the results are very stiff hulls. One of Specmar's kind of signature items is a pair of deck-to-hull full depth...

Re: Newbie introduction

BKFab, hadn't thought the boat as gunning skiff but if that's the way it will be used (not as a pushboat) then the bow's wider deck at the stem may well be a good idea? Don't know? The hull's lines are pretty generic for Specmar and their scantlings are usually "military grade". They do design and b...

Re: Newbie introduction

BKfab, you're remarking about the Profile View lines? Don't see the push boat bow frame on the Valco!! Of course, you don't have to add the push-boat squared off bow to the hull- you could just build her as a conventional bow. Probably other Specmar lines sets similar to the Sitka w/o the bow push b...

rob, why not just extend the stern? Seems an easier method? Are the lines (Keel rise in Profile; Chines taper in Plan?) constricting toward the stern(?) so you need to add the extension amidships?

greg,
the CG records builders (who register) by their BIN (or builders' ID #) so you may find that you can go to the CG site and look for the ID letters shown?
Just a thought about finding your boats' heritage?

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...

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...
