George Morrison owns M15 #319. George measured his mast and boom and came up with the numbers on the drawing he made (at left), click on photo to enlarge. These measurements are for the early M15 only. The cut off year is not known at this point, but the newer masts are taller, and it's suspected the booms may be longer as well. The right photo is the difference in size for the main at right and the jib on the left. These measurements were made after studying the information on the Dwyer mast Web Site, on their measuring page.

Note: The middle photo is blank (no measurements). If you have a late model M-15 print this and the first photo, take your measurements, write it on the blank sheet and E-mail them to me to add to this page - Billamicasr@gmail.com
