Nobody said your boat is too big.
What was implied is that a 600 sq. ft. sail made from ~9oz. material is going to weigh about 120+lb. ... soak it with water and maybe 160#. and unless your physique is extraordinary, a normal person isnt going to able to wrestle with it ... and probably not two either.
For a point of comparsion, a 400 sq. ft. main of equivalent cloth will only weigh about 75-80# dry. and thats approximately the 'historical' limit that a single person can 'fight' on a pitching deck ... when such HAS TO come off. So, maybe your boat is too big ... to be safely handled by a single hander when the conditions so merit, probably too big for even two.
The point remains, that when an in-mast furler affects much more than a 30% SA reduction you dont have a 'sail' anymore, you then have essentially a 'pointy on the top' shaped flat-plate aloft. ... and youre not going to be able to go anywhere but 'downwind'. With a slab/jiffy/boom-roller reefing, the important 'broadseamed'/curved sections are always exposed to airflow.
So I guess what Im stating is that for greater SA reduction than a 'first reef' an in-mast furler is ..... almost TOTALLY WORTHLESS for sailing at any angle much above a beam reach.
