One group of plans I have is of "webs" that extend from Main Deck to Second deck at the outer part of the hull (outside armor)
A second group of plans is of nontight "bulkheads" that extend from main deck to third deck at the outer part of hull (outside armor).
What's the difference between a web and a bulkhead? They look the same (use the same thickness plating). The only difference I can see in the plans is the bulkheads are two decks in height while that webs are one. i can't image that is the technical difference between the two terms
