[quote=texastuma][quote=Edchris177]We have an N5.7 & a 5.0. Both have Diamond wires. Keep looking around, you should be able to find a 5.2 mast cheap. Quite a few of old/wrecked 5.2’s around. I had a spare 5.2 mast from a wrecked boat, but that was 10 years ago, I gave it away.
The Hobie mast, (I broke the pivot on my H18), is very easy to break if you let the mast swing sideways at all while raising.
At the top of the page, to the far right, is a FAQ section. There is a link there that will show how to load photos. Make yourself an album, & load all your photos there.
As mentioned above, if you see a single frayed wire in standing rigging…replace it.
There are some good albums here showing what people have done with the 5.2.
I have one on early Nacra rudders & how they are rigged. Also an album on the 5.7, much of the boat parts are the same or similar enough that you can figure out how yours should go together.
The 5.2 used two different mast balls. Early ones were smaller, IIRC 1.25”, later ones larger, along with a larger diameter dolphin striker rod. I have an album in TECH, how to make a new striker rod for cheap.
Yours looks like the early model, it has the Center bar dividing the tramp. It’s there to prevent the front crossbar from rotating with mast loads. Many don’t like the “shin basher” effect & remove it. Easily done, but you MUST rivet the crossbeam straps to prevent rotation. There are several threads/albums from those who have done it.
Pressure test your hulls, look in TECH albums, I built a tester for $1. You want to find out if your dagger board trunks leak, (or any other part of the hulls). Also make sure your mast is sealed, lots of threads on that…if not, it will take on water when you dump it, & be nearly impossible to right.
Near the end of TECH albums, Damon has a couple of assembly albums from the early Nacras. You can download the entire manual as a PDF.
Lastly, don’t get wound up on making it pretty. Lots of threads here of new owners want8 g to paint/gelcote/decals etc. Get it in the water, & sail the hell out it. It’s way more fun than working on a hangar Aueen
I’m pretty sure I have an extra Nacra mast base in my spare partsEdited by Edchris177 on Aug 07, 2023 - 12:55 PM. [/quote]
Very good points on checking for leaks. I took an old hatch, cut a 2" hole where a 1" shop vac hose loosely fits. Soap the hulls very well and place the vac on exhaust. I have seen it done with one person simply blowing into the drain plug. You only need 1 lb of pressure. Typically, the back end of the board trunks will leak. MarineTex works great there.[/quote]
