FWIW. my boat had in mast furling when I bought it. It took a while
to become accustomed to it, but it works. If I had my druthers I
would have a furl boom system. I found that you only furl and unfurl
on a starboard tack . A real pain if the wind is off the port. We can
furl, unfurl,and reef from the cockpit and I do like that. You give
up a battened main. The boom furl has none of the aforementioned
drawbacks and the weight aloft is also less.
