I am looking to restore an Alpha cat 18 that I received from a friend. I am just starting to sail and I cannot find much information on the alpha. I recieved it last summer but got hurt and was out of commission until recently. Any help will be appreciated
I know it's an early to mid 70s design based roughly on the original Prindles and designed by the people who started Nacra (likely Geoff Prindle). Given that pedegree it is also likely a pretty solid boat! Based on the photos of a couple of Alphas on it looks right sexy also! I also looks about 10 ft wide which means that you should be able to go like a bat out of hell (extra righting leverage). You are unlikely to find stock parts that are specific to the boat for it (i.e. daggerboards, rudders, castings, etc). Things like rudder systems and mast balls etc can be jury rigged from other boats and daggers and rudders can be custom made but that can be expensive.
I would suggest measuring the existing rigging carefully, and replacing it if its original. Most sail shops can help you with that or APS or Murrays online can make custom rigging for you also. You will probably also have to send sails and tramps to a manufacturer when they need replacing.
Other than that make sure it's solid, figure out how to rig it (ask questions with pics here and some of us can help figure it out) and sail it! Looks like a hell of a cool boat!
contact me via e-mail - I pretty much have as much info as you'll get from a myriad of previous posts...
Treat it as a Nacra 5.2 early for almost all parts and rigging.

It is still one of the quickest 18's you can get for low$$ - if you update the sails and renew the rig. If not, be careful, it's old and built lightly.
