Gary: As Jeremy says, it's personal preference. Here where we normally boat, it's not that uncommon to have 25 - 30 MPH winds and very busy boat ramps. Even our first time out, along with the owner from our marine dealership, it was not too pleasant of an experience trying to get our boat lined up in 30 MPH wind gusts to go onto our trailer (it is a Heritage bunk model, manufactured for our Crownline boat). We'd just like all the help we can get!
There are posts we searched and found here on the Crownline Forum about people who are using PVC guide-ons with their Crownline trailers, but we'd just like some of you folks to please share with us what heights you are using with your boats ... 4' or 5' or 6' or ?
