Re: Bonding and Grounding of Underwater Metals


I just looked through my owner's manual, and it doesn't refer to ABYC at all, so the systems may not be in compliance. It only states the hull plans were reviewed by ABS (American Bureau of Shipping), though it doesn't really give a clear and holistic picture of the design and construction technical and regulatory baseline. Even though ABYC is a voluntary regulatory regime, almost all major builders do indeed build to it, so I'll be surprised if PacSea is an exception.

I've spent the past two weeks on ABYC Standards, Electrical, and Corrosion certification training, so am pretty clear on what's required today. And while the standards do change over time, I'm fairly confident that the bonding and grounding portions have been around since at least my year of construction (1995), but will ask the instructor tomorrow.

Pacsea's aren't designed under the CFR's and can really only operate commercially as a OUPV (Offshore Uninspected Passenger Vessel), aka 6-pack. Anything more than that and the full force of the CFR is invoked for an inspected (COI) vessel.

So, I guess I need to modify my original question:

Does Pacific Seacraft build to ABYC, and if so, have they always? And what is the below the waterline bonding as installed on boats from the factory?

For your lifelines: double braid dyneema or equivalent have worked fine for me for the past 5 years, need minor lashing replacement, but there is no visible damage to the core and they still meet the pull/static test.

I think you know best, but when I checked the requirements that folks referred to on this list for lifeline requirements, I found that many people were wrong or were referring to old requirements or interpreting them wrongly (at least by my reading, which with respect to lifelines says that rope is still approved). As I say, I think you probably know best, but it's worth checking the latest requirements again if you haven't done it recently. If what you say was true in 2004, then Pacific Seacraft blatantly violated the ABYC requirements when building my boat. I really doubt they'd do that -- but I could be wrong. (By the way, if commercial boats are your reference, I think you may find that any Pacific Seacraft also violates the rules on lifelines there, too.)

As I said, I think this is one of those cans of worms that will be hard to get clarity on in this forum.

I'm off to the boat so I can sail it over to a rigger to get his view on replacing my lifelines. I already know that whatever he says, many other riggers will disagree with him. That's boats...
