Building the bulwurk, general use on trawlers. What kind of steel is best suited.
How big is your trawler going to be and what use, The ones you see off the Alaska Coast or a Gulf Coast Shrimper? My preference in today's economy would not make sense and that is Aluminum.....not steel at all, maybe even Fiberglass, but $$$$ talk so Steel is cheaper, but you need to know what you are doing. The designer of the hull should have specified the right /preferred grade. It today's world there are many more choices available. You use a mild steel, most often grade A or B, but some applications call for grade D. Check your blue prints and list of materials. Edit. Ok I understand. There are 2 ways to go. One is use a relatively cheep steel and use higher cost epoxy primers and paint, often requiring special surface preparation just before priming, or two, using a much higher cost steel with more chrome and nickel in it. Grades that begin with #3xxx These are weldable with rods that are available, and can be welded directly to mild steels. However these are 3X the cost. If your a Shrimper, I'm guessing gulf coast. I worked with several boat yards in the 70's installing spray urethane foam for insulating there holes. So I've been around lots of small yards from Florida to Texas. I'd call the nearest steel warehouse and ask what they would recommend. You might find what you want at a scrap yard. I've lucked out several times picking up 1/4 plate scrap$ and I'd bet the scrapyard guy would know just what you need. I know there are places to get what you need in Mobile and New Orleans. Good luck!
Best amusing on right here in a while ,simply heading to the harbour bar to look at the fleet are available ,Booboo edged for me ,preferred the Liverpool one ,probably subsequent time we ll inform Chrispen its just a pleasant raid ,however excellent ,the entire equal
