"In the US Uniform Code of Military Justice (UCMJ) it is contained within the regulations governing the failure to obey an order or regulation.

Well, there's the rust. Then there's the fact that it's not
as easy to repair as fiberglass. And it rusts. Joe wrote: You are out of your mind, Steel is much easier nd cheaper to repair and can be repaired in most ports around the world. Fiberglass can be repaired with stuff from Lowes. You don't even need to be in port. You don't need a welding machine.

Joe since you already have a steel boat, I'm not going to try and tell you it's lousy stuff. Besides, it isn't lousy, it's just not as good (ie strong or durable). Steel is stronger than wood, but there are more than two choices these days. Fresh Breezes- Doug King |

You are out of your mind, Steel is much easier nd cheaper to repair and
can be repaired in most ports around the world. Fiberglass can be repaired with stuff from Lowes. You don't even need to be in port. You don't need a welding machine. Patches or rolls of fiberglass cloth & jugs of resin are a lot easier to stow than spare steel plates, and they are much easier to form into the desired shape.

Mor reliable... depends on your perspective I guess. I've done a lot of QA work on pressure vessel welding. Most of the best welders I've worked with are bikers... don't know why that is. ...

Not sure I would ever trust it. Not an issue with steel. A weld can never be as strong as the original metal. A properly done fiberglass repair can be stronger than the original... in fact, it can be a problem if you make the patch too stiff because that throws more stress to the other areas of the hull. Looks to me like you guys who are already welders have a lot of faith in metal... that's good. OTOH it would be interesting to see your opinion after studying a text on composite engineering. I have done minor fiberglass work for many years, but recently decided to learn more about it & the best books seem to be focussed on aviation. That said, I'd still rather have a glass boat. Did someone mention rust as an issue? Why no. Is rust a problem for steel boats?? Who'd a thunk it? ![]() DSK |

If I needed to repair a holed hull, steel gets the vote for easier and more reliable. Since it takes years of specialized study & practice to become a welder, why would you say it's easier? Not if you have a reasonable aptitude for the craft. Most production welders in the yard I worked at were at the 3G level in less than four months, that is they could pass a vertical up test 1" plate cut and stripped, bent 180 degrees around a mandrel without separation of the weld from the base metal. However, there was a shortage and we were pushed hard to test quickly. I tested to 5G (around a fixed horizontal pipe) and had certifications in SMAW, GMAW, FCAW, SAW, and GTAW processes in less than a year (note, not all those processes suitable to 5G position). Mor reliable... depends on your perspective I guess. I've done a lot of QA work on pressure vessel welding. Most of the best welders I've worked with are bikers... don't know why that is. And my ASME code stamp is on quite a few pressure vessels. I was a college student at the time going to night school, however, lately I've been thinking about a Harley 883 Sporster.

Not sure I would ever trust it. Not an issue with steel. A weld can never be as strong as the original metal. I concur with Joe. It certainly can. If it is fully penetrated, properly tied into the base metal with no cold lapping or undercutting it will as strong as the original metal. (provided you use the proper filler metal). You do have to be somewhat concerned about shrinkage at the heat affected zone, but that can be handled. A properly done fiberglass repair can be stronger than the original... in fact, it can be a problem if you make the patch too stiff because that throws more stress to the other areas of the hull.

I'm not promoting steel as the best boat building material. And you're right, it is a matter of perspective and circumstance, what's in your skill bag. I've done both (although never to repair a holed hull with either) and my druthers would be to weld a repair. That said, I'd still rather have a glass boat. Did someone mention rust as an issue?

And you're right, it is a matter of perspective and circumstance, what's in your skill bag. I've done both (although never to repair a holed hull with either) and my druthers would be to weld a repair. Part of my point is that people go with what they know. I am not a welder. It also seems to me that materials & tools for fiberglass repair are much simpler & cheaper & easier to carry around than materials & tools for welding; for that matter, materials for fiberglass repair are available at Home Depot... so is some welding stuff, of course... As for learning, it's easily possible to teach people to do first-class fiberglass molding in two or three days. The problem is that they're not likely to be diligent enough once teacher is gone, and somehow it does not seem to be the type of work that most people take pride in... "Gee, it looks just like *real* fiberglass." The result is that most fiberglass workers cut corner when they shouldn't and the repair is weaker (especially if it involves a secondary bond). That's one of two reasons why I do it myself (and it also proves an old old saying). As for the motorcycle/welder connection... ain't the world a funny place! DSK |

That's a girls bike, Frank Scotty Well, not a matter of image for me and I don't want it for touring. basic local transportation with a little fun thrown in. Every morning I get in my truck and ride about 5 miles one way to a trail head and then I run 5-8 miles. Ten miles with truck mileage. The bike would be more fun and less gas. Besides, most of those so called " tough guys" that I know that have big Harleys put them on trailers or trucks and haul them to "ride ins" Now that's really macho. And they couldn't run 80 yards much less 8 miles. And it's a matter of perspective. When I was a kid a 300CC bike was considered a "big" bike. Pushing 60, I want something that is fun without busting the bank. Frank |
