Hi,
I am busy building a model of the Bluenose and in Jenson's book the blocks use in the running rigging are all listed as "13-inch triple", "12-inch double", etc.
I would like to know which dimension the 13-inch refers to: sheave diameter? Something else?
Also what proportions should I use to determine shell height, width and thickness for each type of block? Are Monfeld's proportions also applicable to blocks from the early 20th-century, or is there a better resources for that era?
Thanks in advance for your help!
Cheers,
Simon
