There are several blocks on the boat, and they're otherwise perfectly serviceable.
The closest I've come is McMaster Carr, but they don't have metric sizes.
Any source would be much appreciated.
Mcmaster Carr does have some metric sizes, like these:

and Drug Administration (FDA) Compliant, National Sanitation Foundation (NSF) Compliant, U.S. Department of Agriculture (USDA) Compliant
Look here for more sizes, etc: McMaster-Carr
