I did a search for Topaz and saw a post that was similar, but didn't hit all the points and wanted to run it by the group.
My wife and I are sailors of cruising cats and are both in our early 40s (no kids). We have a home on Lake Gaston in North Carolina which can see fairly decent wind. (15-20 knots) where we are located on a decent basis. Normally when the wind is up, the motor boats are less frequent, and you are generally battling small wind whipped waves and an occasion monster from a wake surfing boat (which is still nothing compared to an ocean wave).
We have zero experience on a small cat. As a kiteboarder, I am looking fun to getting the boat up to speed, hanging out of the trapeze and flying a hull. My wife is open to those things, but not quite as keen on them. So we need a performance boat, but not one that is going to punish beginners from small mistakes (boat can also not be fragile).
The cost of a Topaz 16 CX with furling jib and furling Code 0 with just about all the other extras is around 13k. The cost of a Nacra 500 with a similar setup is around $17.5k. The used boat market in our area seems to consist of old junkers, and I just don't have it in me to drive around a examine the slim pickings that are out there.
Is it worth up-spending for the Nacra? From the specs, I don't see a huge difference. Nacras do however have a much bigger and established dealer network. Topaz seems to be pretty new in the CAT space, but I actually love the idea of a plastic virtually indestructible hull. Our cat will be on a PWC lift on the dock. Our dealership would be East Coast Sailboats which is about 3.5 hours away from us. They sell both brands. The try before you buy is going to be difficult for us, and to be honest, we wouldn't have a lot of knowledge to really judge what will be better in the medium term.
Thanks for the advice.
