Hi Luffed, a few thoughts from a TheMightyHobie18 (and previous Hh16 owner). I love my TheMightyHobie18... but it is a HEAVY MONSTER...
The mast is also a beast! Perhaps i am a whimp (I don't think so) but I can barely lower it alone (no chance of raising it alone). I either have to have a friend help or use an E-Z mast system (GIN pole)
The dagger boards are a constant worry that you eliminate with the H16. I sail in Clearwater Florida and it is pretty shallow in the Intra-coastal (except for the hour of high tide) so i am CONSTANTLY worried about hitting bottom (that’s a VERY VERY VERY BAD THING) Without them fully lowered i have other issues...
If you get an 18, try to get one with post 1986 rudders (the old system stinks, and the upgrade is very expensive and not fun to install.)
Lastly ... there may be a little more room onboard an 18 but unless you plan to sail in deep waters are very strong, don’t mind the extra weight.... i would consider the 16. It’s a good boat, lighter, less parts, and performs very well.
Personally.... hehe i want to upgrade to a Nacra... <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
Enjoy!
