Transferred to the Pacific fleet in 1943, Massachusetts participated in the Solomon Islands campaign and the Philippines Campaign, and in the latter campaign took part in the Battle of Leyte Gulf. ĭuring World War II Massachusetts was initially assigned to duty in the Atlantic Fleet, and exchanged shots with the Vichy French battleship Jean Bart during Operation Torch. Among the ships armed with 16-in (406 mm) guns during World War II, Massachusetts stands out because it is believed that she fired the US Navy's first and last 16-in (406 mm) shells of the war. She was the seventh ship of the United States Navy to be named in honor of the sixth state, and one of two ships of her class (along with her sister Alabama) to be donated for use as a museum ship. USS Massachusetts (BB-59), known as "Big Mamie" to her crewmembers during World War II, was a battleship of the second South Dakota class. For this specific repair I 100% disagree that marinetex can be used alone.Massachusetts off the coast of Point Wilson, Washingtonīethlehem Steel Corporation (Fore River Shipyard)ĩ × 16 in (410 mm)/45 caliber Mark 6 guns Also don't forget that this is the area where the bow stop rests on the boat. To say ther is no load there is ridiculous as there are going to be loads applied any time the winch is hooked to it. The are in question is right next to the bow eye. But those repairs were not structural, they were only leak plugs. I've used it to plug screw holes in fiberglass boats and a small tear in an aluminum hull and it worked great and I would consider those repairs permanent. Heck yes if it is the right kind of repair. Even Ondarvr came to this conclusion and he is one of the most respected on this site with regard to composite repair.Ĭan MarinTex be used for a "permanent hull repair" as they say in their literature. If it is structural, the repair MUST include glass fibers to compete the composite matrix.
How is this NOT structural? We are not talking about simply being worn through the gel coat here. His picture I looked at looks like his description is accurate.
The original poster stated that the hull was worn almost all the way through. Layup a 1/8" thick laminate with the same epoxy and glass cloth and you won't be able to break it without using tools.

Then remove this coin after full cure and throw it down on a concrete sidewalk. Well pour an 1/8" thick layer of epoxy in a waxed cup and let it cure. The same epoxies with fiberglass fibers can have tensile strengths to 40,000 psi, 60,000 psi or even higher if the fiber directions are carefully controlled. The strength of a fiberglass laminate, whether epoxy/fiberglass or polyester/fiberglass comes from the matrix which includes the glass fibers. Despite what you want to believe, marintex is not strong. Sot MarineTex has a lower tensile strength that plain old epoxy. Typical plain epoxy resins by themselves have a tensile strength of around 8 to 10,000 psi. MarineTex has a tensile strength of 4,000 psi from their own website. However, the engineering specs don't lie. MarinTex is a good product for the right applications.
