David, The seats that I'm building don't fit inside the beams like those you have. But you should be able to make a mold and cast some fittings, or ...

I've sanded down two of the 5.2's and one 5.8 and all had the black undercoat you mention. All also had the chalky gel that would wash off when hit w...

John, That would be me. I have built a set for my Nacra's and have mounted the first on my Nacra 5.7. The design will work on any CAT with 4" round...

Update on wings. Just picked up some new tubing yesterday to make the final proof of concept. Hope to have things welded up by Thursday and then of...

Pulp, My 2 cents. At your weight bigger is better if you want fun and not boredom. I currently have a NACRA 5.7 and a NACRA 5.2 sailing. Both get n...

Southern CAL Baby! Almost never have to stop sailing, but it will be HOT into November typically. That's about 25 more weekends 🙂

If it is gel coat and rubbery I would think that maybe they didn't add the wax in the final coat. Gel coat will not cure when exposed to air. You ne...

The daggers on the 5.5 and 18 are the same as those on the 5.2's, which are considerably smaller than the 5.8's. Don't yet know about the 6.0, but I ...

I'll try to take a look on Friday. I have a 5.8, 5.7 and a couple 5.2's. If I recall, the 5.8 had a shorter rudder blade than what my 5.7 has. I be...

I'm working on some custom wing seats for my 4 Nacra's with the 4" round crossbeams. I had designed some last year that worked out well, but I want t...

Kevin, I'd be interested in seeing a picture of your setup. You mention casting nuts, but my 4 nacras have a bolt that goes through rounded bottom c...

I've never seen a setup on the old boats with just the casting used and not straps. The casting is just a clean way to keep the beams from rotating a...

Don't let the 'V' brace scare you, they are a piece of cake to make. Simply purchase some aluminum flat stock bar (I think 1/4" thick by 1 1/4" wide ...

They told me last year the 5.2 couldn't enter, had to use the 5.7 or 5.8. It's a free ocean, so you can still make the run, but not enter the race of...

Get some round ball type polishers that will fit on the end of your drill motor. I got a bunch of different types from McMaster Carr. I kept getting...

Bob, It is something like 0.086", which you can't find. You'll have to go with 0.125" tube if you are trying to purchase new, which I did when I reb...

Haven't been able to count on a good wind here lately, but it's hard to complain when one can be out 'Paragliding' in January off the cliffs. I've be...

The water is 60 and the air has been 75 - 85, who needs a wet suit? Almost went today, but for that thing called work. Checking the weather now to s...

Let us know what you think of the purple when you get it. I have the green and the red for the two Nacra 5.2's, and I'm going to redo my Nacra 5.8 hu...

I believe that the data are for best case conditions, and parts in new condition. When I fly my planes they have a certain rating for say normal util...

Doug, I haven't had them too long, just got them toward the end of July. Although the frame is plastic, it is glass filled and seems pretty rugged....

Doug, The top hinge point on the assembly is adjustable. The piece slides up and down in a groove and there are small holes in the main frame. You ...

Buy them! I've committed to purchase 4 sets for my 4 Nacra's and have taken delivery of 2 sets so far. Installed on the the restored 5.2 (the mean g...

The crossbars are no big deal to replace on the old Nacra's, especially the rear one. They are a simple 4" aluminum tube. You don't need the slot in...

That's Euro's, which is over $6,000!!! I'll have much less than that into each of my 5.2's and the 5.8 fully restored with nearly new everything. An...

Thanks for the input so far. I did speak with Dennis today about the SNU and was informed about the bend. He suggested pulling the tip down 2". Th...

Chris, Try Uship.com , I've used it several times to move product and equipment that I've purchased for my business. You post what you need (a pictu...

Are the Prindle crossbeams 4"? If so, then there is a good chance that the wing seats I've designed for the old Nacra's will work. Time allowing, I'...
