Looking to get my hands on a BROKEN/THRASHED NACRA 20 second generation rudder and a dagger board.

You have one laying around let me know.

2nd generation??? I heard those rudders were barely useful as a paddle...

I have the broken off head of 3rd generation rudder and I'm fairly certain I also have full, 100% working condition, pro-tuned 3rd generation rudder lying around.

Looking at making molds?

Dude, step away from the bowl.

Dude! Didn't you tell me you prefer the first generation to the second generation rudders?

I like the third gen rudders myself. But that probably just means I'm ham-handed on the helm and can't appreciate the joys of ventilation from the first gens. You interested in parting with the one you have laying around?

There are 3 generations of N20 rudders:

1) 1st gen, narrow blades
2) 2nd gen, fat blades that no one has great things to say
3) 3rd gen, properly designed fat blades. Also in use on the Infusion Mk1.

My boat had Phil's foils tuned 1st and 3rd generation rudder blades. We used the 3rd gen blades for most of our racing until one literally disappeared from the bottom of the transom down in the Tybee. Then we switched to the 1st gen blades, which worked fine for distance racing, no real ventilation/cavitation issues. We used them for 1 or 2 buoy racing deals afterwards, and I didn't really like them for that style racing-at slow speeds, aka on the start line in light air, they didn't have the authority I experienced with the Gen 3 blades and am used to on other boats (those monohulled things).

Keith, PM sent.

I have a new 2nd gen rudder - still in the plastic that I'll let go for $100

Wonder if you could "3-d print" foils like that?

Possible with SLS technology. Could possible use a normal (ABS Plastic) 3D printer to make the male on which a female mold is pulled. Normal ABS 3D printed foils will not stand up to the loads.

that's what I was thinking - use it to make/modify a mold for a cheap(er) way to tweek a design...?

2nd gen rudders never could be tuned quite right. Dig up a set of first or 3rd gen blades if you can.

John,
My boat came with a bunch of 2nd Generations and 2 sets of 1st Gens. I sailed with the 2nds for a few years before I even tried the 1st gens. Being used to the 2nds, I hated the 1sts. They seemed to cavitate too easily. I did on GT with the 1st and went back to the 2nds. Would like to switch to the 3rds but now that you need a tube of KY to buy them, I may not.

I have a 1st gen rudder sitting in the basement. It's not usable in current condition, but could be fixed fairly easily.

I have four 1st gen rudders and three daggerboards that I need to unload.

Jake, I'll buy one or all of the daggers. I tried to pm you but your box is full.
