Hi, I am pretty new to cat sailing, though I have previously sailed small monohulls for many years. I was wondering if i could get some advice from some of the experts on this forum. I have been lurking for a while and have learned a lot, and have been entertained even more.

Here is my situtation. The vast majority of my sailing will be single handing. I purchased a Wave and this is my second season sailing it. I really enjoy it in higher winds (15 plus), but it has quickly become a bit "tame" for me in lower winds. I have been sailing the Wave mostly solo, but have also been taking my 9 year old daughter out on it with me, and she has been learning to sail it as well. I don't take her out in the higher winds (my bet is after our first capsize my wife, who is a non-sailor, will put a stop to her sailing with me - but we'll see.) So, it works fine for the two of us in lower winds, for the time being, as my daughter is learning. It is also a blast for me, solo, in the higher winds. But now I am looking to add a second boat that I could single hand in the lighter stuff that will be a bit more excitement in the lower winds - ie, hull flying, etc. I should add that I weigh about 160 pounds, and am not interested in racing. Since the second boat would be just that, I am looking for something used that would not be too expensive, would be faster and more exciting to sail than the Wave in 7-15 mph winds or so, that would work well for single handing, and that i could right myself. I would also prefer a unirig, as that is what I have always sailed as a monohull sailor. So far I havent had too much trouble tacking the Wave's unirig, even in pretty strong winds/ waves. I did at first but all of the helpful suggestions on this forum have made a big difference. I am fortunate in that I could store the boat mast up at my cottage on the beach at Delaware Bay. I would be interested in any suggestions as to what boat or boats might fit the bill for my situation.

On a more specific note, there is a Nacra 5.0 listed for sale that is located pretty close to where I sail. I see that nacra used to make the 5.5 uni. The 5.0 looks like it is a sloop rigged cat. Is it possible/ feasible/ desireable to sail the 5.0 as a uni, or would this be a problem due to boat design or other factors?

Sorry for the long message. Any and all reactions, comments, suggestions etc would be much appreciated.

Many thanks!
