Definately 2 fleets. We've been dealing with this in the GT for years and now are running 2 fleets. The Portsmouth numbers don't reflect the performance accurately enough for the conditions usually found in distance racing. The year that Team Tybee came to the GT, an F18 still corrected over them as well as Alex Shafer and John Tomko. Imagine if they had 2 more days to rack up more time on the water. The F18 would be even farther out there. You'll see, when we get reachy conditions, the good F18's will be able to carry the chutes much longer than we can on the N20. With the spinns up all together, you wont see much difference in speed, if any, unless the wind is super light. About the only range that you see the N20 actually reflecting the time difference between the two is light air going to weather.
