Dont sound like a large difference in the pure physical sense for real world racing? But the mental difference might be huge.
I dont want to wear you out on SCHRS Simon, but if one was to add sailarea to the main, or remove weight, how much area/weight does a difference of 0.002 make then? Just to put the question into perspective and as long as we all understand this is a hypothetical discussion.
Rolf, no problem, doing this on SCHRS is very ver yeasy.
To make it clear; I took a FULLY OPTIMISED Single handed F16 and changed the beam to make it less; this gave the 0.002.
I do not have the measurements for the Tiapan.
To take a thinner F16 and get it back up to 0.982 with sail area would require an additional 0.1sqm of mainsail or 0.5sqm of Spi.
