Re: Boat purchase, 40’ home built

Re: specmar 2434 plans, your thoughts

noexcuses2, I think everyone can agree that Specmar boats are drawn with very heavy scantlings? They usually show a couple of 1/2 or 1/4 buttock longitudinals that are deck-to-hull and combining these with the topsides- you're looking at a "combat vehicle" level of stiffness/rigidity in the hull. Wh...

Re: Boat purchase, 40’ home built

Sea word, not based on salt or no salt. Corrosion can be from several sources and cleaning the bilge with soap and water (first) then rinsing and seeing clean uniform surface of aluminum gives you a "go-ahead" from that worry. We've seen copper and brass/bronze fitting in fuel, water and other syste...

Re: Boat purchase, 40’ home built

Sea word, I'd make some remarks about buying a home built boat where the owner/builder's records may not be available to either interview or documenting the project as it was built? First, in my experience is to verify the alloys used; if possible? You may not know about the huge alloy scandal some ...

Re: Mounting Volvo transom shield on wavy 1/4” transom question

Eli', Chaps, readers of the AAB.Forum, the 'best' transom panel for an I/O is not a single plate of aluminum which can be, depending wholly on the design of reinforcement, subject to weld distortions and 'waves'. In 1978 I was faced with my first I/O stern and after looking at two other 30'er's with...

Re: to windlass or not to windlass??

in small boats- deck area and clutter seem to go hand in hand? So if you use a capstan head/windlass to pull an anchor rode there is a bit of clean up- even if you coil in a bucket or tote as the line comes in- you're giving up deck space to more clutter. On the other hand, winch/drum or windlass/ca...

hersh'14 there are couple of observations about your question that might be worth your consideration? What does your use of the term "deep V"- mean? Is that a 27deg deadrise as the open ocean racers use the term? is that 12-15degrees at the transom? 90to 95% of the little production run-abouts have ...

Re: Building an offshore aluminum duck boat. What material?

I need it to be 100% aluminium I think you may have answered your own question? I prefer 5086 as that is most cost effective and 'stiffest' readily available alloy in the PNW. Other areas may have 5083 which is very nearly the same material. Bending bulkheads? do you mean flanging the panels? - not...
