If I am understanding you correctly, the extra feet mean less agility? If so, yes!

The 16' length and 8' width seem to mean the Nacra 500 is less agile, especially in light winds. Have heard a number of complaints about turning the longer boats in light winds, not to single out Nacra 500.

In looking at various boats, I use the Hobie Wave to start comparisons. The Nacra 460 is only 1' longer than the Hobie Wave, 1' wider, BUT has 5' more mast and about 40 square ft more sail area (includes jib?).

Assume the 460 speed factor a notch or two lower than the H16. 218 sail area vs 135 on Nacra 460. However, at 12-15 knot winds the H16 is overpowered, I hear?

Plus, at 280 lbs, Nacra 460 is only 45 lbs more than a Wave, but still in a manageable beach cat weight. However, it's weight carrying spec is much lower!

There seem to be three distinct levels of boats (can I say that among all the experts around and not get pelted?)

First, the recreational, big-weight carrying capacity. Second, the moderate performance boats with more power and less load capacity. Third, all the high performance boats. Some overlap.

Lots of factors to compare but for moderate to heavy wind conditions, more comfort on the moderate performance boats in those winds -- especially for solo sailing. Plus better agility in lighter winds.

Yes, do take all this with more than a grain of salt. I live to be heckled. Heckle away!
