My father who is a life-long fisherman and owner of many fishing boats took one look at my 170 and made the comment that he felt the boat was going to be hard to get back on the trailer and that I should buy some trailer guides. So, with all due respect to my father, what has been the experience of those of you that have the 170. Is it hard to get it aligned properly and sitting on the bunks when you bring it out of the water?
