trouble running on mac with Wine & Wine bottler

hi all!
i am a volunteer for the Kootenay Lake Sailing Association in Nelson B.C. Canada. i am trying to find out how to calculate handicap scoring for the Dinghy Youth Program as well as the Keel Boats.
but first i must get to know and understand sailwave.
i cant seem to get sailwave to run on my mac. it comes up with
"cant not open INSTALL LOG"
did i intall it wrong?
is there an online version where i can do my calculating without having sailwave installed on my computer?
my cumputer is a MacBook 2.4GHz intel running OSx 10.5.8
