Some of them.

Again, some of them - I've included his elven cutter design.

Well, in Spelljammer, a 'ton' was originally 100 cubic yards (although 
there has been some debate about this).

In the real world, the volumes of ships were also given in 'tons' but 
these were 100 cubic feet.

Hmm.. I've actually done a bit of reaserch trying to find out if there 
was a simple relationship between ship size and weight for a given 
design of ship - but I couldn't find a lot of info on the subject (so 
far) - and I can't find the notes that I did take ATM.

However, the War Captain's Guide changed that: Bith AR and MC were 
both dependent on hull material, while Hackjammer has hull points 
dependent on hull material as well.

I'll contact Static and see about getting the table posted on BtM. In 
the meantime, do you want me to send you a copy?

Well, Hackjammer uses 1,000 cubic feet for a ton, which is a 10' × 10' 
× 10' cube - which could make estimating the volume of some designs 
easier.
