Wind Surfer, there's no way I would ever have sailed Hatteras if we weren't living in the RV. We're originally from Austin, and since going to Corpus was only a four-hour drive, we could make a quick decision to go down there if the wind looked good.
I'd heard about Hatteras forever, including the part where you can sail flat water on one side or carry your stuff across the road and sail waves. I just wanted to SEE the place, but I got to to sail it because we were more or less in the neighborhood. AND I got to use my own equipment, which makes a huge difference to me.
We never would have made a dedicated trip there to windsurf. We're just not serious enough about it to do something like that. But I got to sail it anyway. That's one thing I love about fulltiming.
If we ever do get out to the Gorge, it will also give me the freedom not to sail. I'm not interested in waves or crowds, and if I'm just living my life as usual and just happen to be there instead of somewhere else, no big deal. I'll do it if I feel like it.
In Hatteras, I sailed I think 10 days out of 40. My boyfriend sailed a lot more. I spent the rest of my time waxing the RV. We both greatly enjoyed our stay.
You didn't mention whether you still have your gear. You can rent a lot of places, but part of the appeal for us is being able to sail if it's convenient. In fact, now that I think about it, the only places we've been where there are rentals are Hatteras and Corpus (and in Corpus, you have to sail Bird Island--they won't let you take the rentals to the bay). We wouldn't have sailed San Luis Reservoir or Lake Lopez or the Salton Sea if we hadn't had our own stuff, or any of the smaller lakes across the country that I have my eye on in case it's windy when we're passing by.
If you do have your own gear, the biggest issue will be equipment storage, especially for fulltimers who need to have all the stuff out of the way when they're not in a windsurfing location. People taking an RV windsurfing will often pile a lot of the stuff inside and just leave it outside while they're there--that doesn't work for fulltimers. Plus, our roof is off limits for equipment because it's covered with solar panels and satellite dishes.
So you might have the challenge of finding an RV you like for living, as well as one that will accommodate the equipment. We lucked out in that department, but if I were buying something now, I would do a lot of measuring and calculating before making a decision on the RV.
I hope your plans for fulltiming work out, and it would be fun to cross paths one day. Like out on the water...as long as you're the type to know that port tack yields the right of way.
