Had a removable inner forestay on my
C&C 38, it was perfect. Most days I could use the 150 on the
roller furling up to about 17 knots, above that I reefed the main and partially furled the
head sail. Or I could dowse the main and sail on the headsail up to about 20 knots.
Having the removable inner forestay made tacking the 150 much more convenient, in the real heavy stuff I could use a third reef on the main and a
storm jib on the inner forestay, above 30 it was just the
storm jib on the forestay. That was on a 15,000 lb racer/cruiser, these days that boat would be considered a cruiser/
racer. But handled itself well in challenging conditions, and comfortable to boot.
My
current boat is a 47'
center cockpit performance cruiser, but at 40,000 lbs with full
tanks is no lightweight, it too has a removable inner forestay. This allows me to tack and control the 140% headsail easily during 75% of the conditions we encounter, it also allows me to install the forestay and fly a yankee with the headsail in moderate reaching condition when we're not tacking much. It also allows me to fly a storm jib in heavier conditions when the
head sail is rolled up. Both sails on the inner forestay are hanked on.
Otherwise, with a fixed inner forestay and any headsail over 100% you have to furl in the head sail and then unfurl it anytime you want to tack. It all depends on what type of sailing you want to do and where your sailing, but if I've learned anything on my sailing
experience it always seems to be heading into the wind no matter where I'm going, even in places known for their reaching conditions. How many times have I heard someone say "boy, it never blows that way around here", it must just be my luck in life.
On my
current boat it does require
running backstays to help offset the
mast loads of the inner forestay when installed, but I find that a minor hindrance, due to the fact that in most circumstances when using the inner forestay we're not in a tacking duel but running on pretty long sustained courses, either off wind or in heavier wind. I like the flexibility this changeable
cutter rig allows.
The
running backstays have also allowed me to better control
mast pumping even when the inner forestay wasn't in use.
