Last time I launched I had a mystery issue.... pulled the straps, turned on the blower, backed it in, fired it up and it won't move.....
Yeah, OK, mental check...in reverse gear, yes. Drive down.. yes....straps off...yes..
WTF???
Turns out one of the bunks had the bolt that holds it break on the way down the ramp last time. So the bunk floated up as the boat slid back. The bunk actually wedged itself against the next step in the hull.
So its basically got a bump stop holding it on the trailer. Aaargh. Other folks in line and I'm there like a dork....blocking the ramp.
I had my buddy back it up more and I powered forward and pushed the boat a bit sideways by hand, enough so that I could float around the damn bunk.
As he pulled it up I could see the bunk all cockeyed on the trailer...
Temp fix with some drywall screws held it till I got some galvy bolts and reattached it..
