Yes, but this capacity plate from a 1978 says it is US cost guard capacity information. ? View attachment 4409
The capacity plate on the 1978 Hydrodynes Said "This boat complies with U.S. Coast Guard safety standards in effect on the date of manufacture." This implies that there were U.S. coast guard safety standards in effect at the time and that this boat complied with them. The U.S. coast guard since then has changed their standards but at the time it did pass the standards in effect.
