It appears that the Impex Force Cat 5* has 22.66 sq ft of wetted surface area at 250 lbs displacement (according to the Sea Kayaker Mag tech sheet). The F1 has 19.94 sq ft at 250 lbs displacement (from link below).

Surprisingly, someone has already compared the F1 to the cat 5, and lists KAPER drag numbers for comparison:

http://www.qajaqusa.org/cgi-bin/TechniqueForumArchive60_config.pl?review=68703

So, up to a bit over 3 knots the F1 should have an advantage, but the cat 5 clearly has the advantage at higher speeds. If you can push it into that range and maintain it, anyway.

* Note: I can't say for sure if the cat 4 and cat 5 have the exact same hull but overall dimensions are the same at 18' x 20.75" the only difference appears to be the deck is taller on the cat 5.

: Just looked at the trip photos and it appears to be an Impex Force Cat 4.

: At any rate, I don't need an excuse to build another boat, just want to do
: it!

I've done that, too, but only with the Guinness.
