this is my champion 186. any of you champ owners ever seen a champ do this? my opinion is that it is NOT stress cracks but because it is a black boat and was left out for to years w no cover. everyone knows how black draws the most heat. the sun baked it and caused it to crack and they are not deep cracks. have owned this boat for almost two yrs and love it. it just needed a little tlc and its gettn it now. got the boat torn all the way down and shes gettn a face lift
