I am contemplating buying a 2006 175 Sport with 150 hours and was looking for some advice/guidance. I live with Southern Ontario with access to lots of lakes. I own a tow vehicle and have 2 young kids aged 6 & 8. Is a 175 big enough to use on a larger body of water such as the great lakes. I have 5 weeks annual vacation and a fairly flexible work schedule during the summer months and was looking for a way to get out on the water to do some exploring, tubing etc. vs watching others do the same from the beach. Thanks.
