Re: Twin engines vs motor plus kicker

AM bite, twins offer a smaller torque load on each crankshaft- relative to the entire load being moved. So a little longer service life is gained by twins- due to top speed/displacement loading per engine. Twins offer a natural offset between the two wheels so harbor steering in a breezy afternoon (...

Re: Hull corrosion in bilge area

Re: Hull corrosion in bilge area

PNW, I don't believe I've seen that particular corrosion 'growth' or type before- so all I can do is speculate! First, if this is in the battery compartment, perhaps the acid/water/mixture isn't correct and you've been evaporating some higher acid content vapor? (Speculation only) If you're charging...

Re: shore landing and deep V

AM bite
that sounds more conventional- not sure of Pacific's deadrise angles but 18 deg sounds like something we've come to expect.

I think you're following a good path to see if you can organize a test ride/drive/outing before making a decision.

Re: shore landing and deep V

AMbite, is that 18" of deadrise or 18 degrees? 18" would be a pretty steep bottom and likely to roll over on one chine and float from keel to chine instead of chine to chine with the keel down? if the builder will help? finding existing boats, or owners who will consider giving you an on the water t...

Re: How to repair areas of corrosion & electrolysis

mlt, some remarks in general about the photos in your blo-boat hull.

Re: Corrosion on anode

OceanTrvlr, The anode is aluminum (1/2" 6x12 plate I cut in half and drilled for mounting), and I think it's working wonderfully. Is the plate an aluminum anode alloy? Or is it just a piece of 6061 or 50series? Just curious, surface action is odd looking for sure. I think the actual anode alloys are...

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?

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...

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...

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?

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?
