[quote=klozhald]They look the same, but:
Boom on the 18 is elliptical with external outhaul in the kerf.
Boom on the 18-2 is square, has internal 4:1 outhaul car and is slightly longer than the 18 due to the different sail.
The 18-2 and the 19 share the same boom.
Pin head sail is slightly bigger on the 18-2 as is the jib. The square top main that was an option on the 18-2 is a lot bigger, fewer battens and was a mylar laminate yet came with a dacron racing jib.
18 sail area with pinhead sails 218 sq ft
18-2 sail area with pinhead sails 233 sq ft
Some of the differences are visually subtle, like the beams being 8 feet vs 8.5 feet, and the crossbars were drawn from the same extrusion, just longer. The 18-2 and 19 used many identical parts (trampoline, crossbars) but they were a true redesign from prior Prindles. I had a P16 for eight years and sailed on my friends 18 when I could. Aside from local lakes, I sailed it in the Pacific (So Cal), Sea of Cortez and Couer d' Alene Lake in Idaho. They are great boats, but I had to sell the 16 to buy the 18-2.
