H-20 N-6.0na N-20
And have crewed on a Tornado.
So, against that - the N-20 is very responsive and carries heavy crew weight well (very important to me). It was designed with the spin so you don't have the cobbled-up engineered feel you have on other boats. There's lots of room on the tramp, and the tramp is very clean in contrast to the flesh ripping devices on the N-6.0 and H-20. The carbon stick is a very nice thing, and not just from a rigging standpoint - the lighter weight aloft means the window of recovery is much greater before you take a swim. The bows are insanely bouyant. As said elsewhere, there are things we've gotten away with due to those two things that would have induced the big swim on the other boats. Up and down wind it feels very natural and balanced. It is responsive to the helm almost to a fault, similar to my H-20, very different from the feel of the 6.0 (heavy feel to the helm). The feel of the N-20 when it's lit up with the spin is addictive, and the hull shape works very well in that mode.
Cons (as far as I'm concerned) - the bouyancy in the bows can be a detriment in some conditions where the 6.0 would just cut through. Looking over old Worrell and Tybee tapes it's interesting to see how the 6.0s go out through the surf versus how the N-20s do it. I'd like more freeboard to the hulls - maybe the 6.0 spoiled me, but I hate it when the rear crossbeam or tramp catches a wave (a behavior shared by the H-20 and T). I know, just fly the hull higher, still... I don't like it that the rudders cavitate from time to time (I've experienced it more upwind in big chop), and yes, I know there is an updated design (that nobody uses). And lastly, while the boat feels real good up and down wind, to me it feels more unsettled and twitchy when reaching, while the 6.0 feels like a rock solid freight train. There are conditions where we've gone boat for boat with the 6.0 (without spin) against the N-20s and come out on top or kept even - although usually ended when the N-20 spins could be used to best effect.
As for righting, the more difficult boats to right that I have owned have been all the Hobies - 14, 18, and 20. By far the easiest to right have been the 6.0 and N-20.
Just my opinion... | | | Re: I20

To me, seems when I am running the ropes and someone else is driving I get a better feel for the boat. Also, then i can just yell at them to "pull or push" the rudders, instead of telling them to pull the ropes.

Posts: 12,310 South Carolina | If I had a wish list of improvements for the I20 it would be first a deck that's level with the main beam on the leading edge. I can feel so much speed bleed off as water pounds the front beam as it flows over the top of the deck (usually under spinnaker in waves). Second, more height for the rear beam...the bucking bronco wave slap is A) not fun B) surprising and can make you loose your balance and C) knocks you out of the speed groove.
(the Mega Cat Playstation had problems with rear beam slap...can you imagine what that was like!?)

In all actuality, it is by far the most fun boat I've sailed. It handles anything you throw at it, from 20 knots of wind to 420 pound crew weights. You can drive it all the way up the beach, and fly a hull in 7 knots. It's easy to right, and easy to control. Once you get it dialed in, hang on!

I know the rear beam on the N20 isn't round, but you could engineer something. I took 4 inch OD al tubing and cut the tops off, basically flipped them, welded them put in a base of epoxy with filler to make up the ID/OD difference and they are nice. Went out today in chop with 20kn of winds and didn't slap but maybe once. Dunno if this screws with the one design deal though... | | | Re: I20

Posts: 1,253 Columbia South Carolina, USA | Many good boats out there, and I have sailed and owned quite a few "bigger" cats...SC 20, G-Force 21, N 20, but the best sailing and overall boat has to be the N20. Always powered up whether light wind or blowing stink, but manageable in all for crews who can push it. I remember owning the boat for a short period and going down to race the boys in Florida. Not much chute time under Jake or my belt and it was blowing 20 at the old moose lodge in Largo. We were so scared we would drop the chute 50 yards from the mark, there were 15 or so N20's flying at us from all directions, and man were we flying. Ahh the memories of the DLW....Never heard of her? Ask around.... [img] http://www.powergroovesailing.com/DLW.htm[/img]

Posts: 9,582 North-West Europe | -1- The rudders stall frequently.
-2- It is waaaay overpowered requiring in 10:1 or more mainsheet purchase that is thrightingly slow in response.
-3- In big wind you need to depower so much that smaller boats like the F18 and F16 are passing it upwind. All that depowered sailarea is just drag. The speed difference is such that halve the time you can pass them through their lee wind shadow.
-4- It is heavy overall.
-5- The spinnaker loads are very large and tiring.
-6- Its bows are so full that 20 footers with a better bow design are faster in winds over 14 knots or so. Think Eagle 20 etc. The only exception is the Hobie FOX here, but that one had other issues
And yes I did sail it more then once. Not with the new rudder design though.
Still, it is one of the best long distance race designs, mostly because of it's fat bows and long length compared to its width, it feels stable and calm which is important for long sail trips. In bouy races it is much less convincing.
Also it is fitted out well and there is heaps of space on the trampoline. I think it is a noticeably better design then its little brother the Nacra Inter 18, despite the fact that they share alot of features.
Generallly a good boat.

Posts: 3,528 Looking for a Job, I got credi... | Never sailed a I20, but have seen a few around when sailing my Hurricane 5.9 (another 20 footer), And my opinion of the Inter 20 was a very solid boat which looked like it should go fairly quickly, but never really got there in the UK; probably because the Hurricne 5.9 was a well established boat already, sailed by good sailors that could usually beat the I20 over the water and the Hurricane (at the time) was only 2 sails.
If the inter 20 had "made it" in the UK before the Hurricane 5.9, it might have been a different story; have to agree with Wouters comments on the bow shape of the I20, but this did mean it was very difficult to pitchpole.

Posts: 1,253 Columbia South Carolina, USA | Wouter, youre right about the rudder stall, but only with the old rudder design,and the boat is quite a joy to sail otherwise. Its demanding no doubt, but I wouldnt do a distance race on anything else. I love my F18, and the F16 looks pretty cool too, but I wouldnt trek up the Atlantic coast on either one in a blow, I'll save those boats for the lakes. Im not saying they cant handle big wind or rough seas, just not 6 days of it, it would literally beat you death. Not many F18's or F16's beating the N20 boat for boat in any conditions around here, but then again the boys sailing the N20 are quite good, and the F16 fleet is just getting up to speed. So maybe one day we will see that here, but for now the N20 is still the dominate "fast" boat and the only boat for the Tybee. Lunch Trey...you see how I defend your big heavy boat? You still need to get an F18....
