If I measure the foot of the jib and the distance from the headstay
chainplate to the mast base, will that give me the jib size (i.e.
150% vs.175%)?

From the Neil Pryde web pages, here's what they say about headsail
sizes:
Overlap-(L.P.) Luff perpendicular expressed as a percentage of "J"
(the distance from the bow to the mast) this figure indicates the
size of a specific genoa. Standard sizes are:
- #1 - 150%
- #2 - 135%
- #3 - 105%
- #4 - 80%
The LP is a perpendicular line measured from the luff to the clew.
So for the R22, "J" is 8.8 ft. The standard 175% genoa has a LP of
15.4 ft. A 110% jib would have a LP of 9.7 ft.
Hope this helps.

There is another way to go for your 1972 boat. Call Bacon & Associates,
Inc. 116 Legion Ave, PO Box 3150, Annapolis, MD 21403. Phone
410-263-4880. They have an enormous stock of used sails, many raced
only one season. They might the largest sail dealer in the USA, but
even if they are not, they are still well up there.
Use these parameters for your mainsail:
- I = 25.50
- J = 9.00
- P = 22.00
- E = 9.00
You can get a serviceable used sail there at a fraction of the new sail
price [like 1/2 or 3/5, those type of fractions.] This may be just the
ticket for your older boat, unless, of course, you devote your entire
waking energies to retrofitting it and making a custom vessel.
You will have to ask them how to measure for the jib. I'm sorry, I lost
that information when my computer crashed. Naturally, you might not get
lucky on the jib, so you might have to have the local loft sew the proper
tape on the luff of the jib to match your roller furler. Again, if the
boat doesn't have a roller furler, you can save the expense by having a
normal hanked on jib, and a jib storage bag. It will still sail fine,
but then you might want to also invest in a working jib.
Hope this gives you another line of thinking.

Luff = mgf dimension 21' 4" max, Doyle = 21' only
Foot = mfgr. 8.5 max, DOYLE = 8' 2"
