this was a metaphor to say, just cause you can get a 5.8 (a rather large powerful race cat).. it may not be the best first boat...
One suggestion that was not explored here is.. if i recall correctly, there is a pretty active group at lake lanier... and some racing. it may be very worth your time to meet the locals, ask a few 100000 questions about the pros and cons of each skippers boat, ask their opinion about the boats available, and ask for demo's (rides) and get a bit of a feel for the different cats.
Heck maybe even offer to crew for a race or help run a race (they often welcome help) to meet the locals.
To me scows don't count as monoslugs, more like a "connected catamaran" most have two rudders and two daggers! They are pretty cool lake boats, an e-Scow is a beast!
I'm pretty sure I could take a Thistle (500lb 3up spin boat) with a Getaway around a triangle course, my local lake has mostly Lightnings and Thistles, some pretty good sailors, and I can sail circles around them with my H18.
The only time they have an advantage is direct downwind in very light air with their big round chutes.
My first twenty years of sailing was all dinghies and small keelboats like the J24 and San Juan 24, once I got on a cat I never went back!
I agree with mummp. Hobie liked their H17 and H18 designs so much they replaced them with the Nacra F17 and F18, er, the FxOne and Tiger. :)
I like all cats but Hobie is like the microsoft of catamarans. Mac(ra) is about 10 years ahead of the game while Hobie(soft) waits a long time to change things up and in the mean time they make a 'penguin' kayak!? :) Hey at least they are still in business and relatively successful. I guess I'm just bitter because after 30+ years you still have to hang off the back of an H16 to keep it from pitchpoling in a stiff breeze. Aside from that they were definitely responsible for making me catch the cat bug!!
I thought ATL76 really should know what this group is all about.
Some of you know that I have falling in love with another boat, it ain't a NACRA, and good Lord forbid it ain't Hobie.
