Sebastian,
My third attempt to get this out, anyway, the 12 x 8, the first
number refers to the diameter of the blades in inches. The second
refers to the pitch, or angle of the blades, and is the number of
inches the prop theoretically should move forward with one
revolution. The greater the pitch, the bigger the "bite" the prop
takes. Chosing the right prop for a given boat and engine makes all
the difference in performance and fuel efficiency. There are so many
variables affecting correct pitch and size that scientific selection
is difficult for the average person. Cin Cin is powered by a 13HP
Westerbeke and a 3 bladed 14 x 8 prop, and reaches 6 plus knots
easily without straining. As for the # 1 Jib, also known as the
Working Jib, I believe it was standard issue with all Vega's. It
measures 145 square feet, with a Luff of 27' 6 3/4" and Foot 12' 1
3/4" and Leach of 24' 1 3/8". It was meant to be hoisted with a 3
foot pennant, to keep the tack off the deck and keep the sail from
picking up any waves/water coming over the bow. I have the figures
for the # 2 and 3 Jibs if you are interested. Hope this helps. Frank
