i do know it is not a "tool" :-)
someone called it as such and thought it redundant to say easyuphaul uphaul
am using a 10.0 with a luff of 536 on a 520/100% mast
as a race type sail with double luff it weighs 7.5 kilos !!
so, 30 to 40 dollars versus a sore back ?
sounds like an easy decision
i have had issues in big winds with 8.5 already, so ....
will try without, but intend to investigate availability n cost here
thank you all very much !!!!
