Very low spring tides lead to extending the trailer tongue to its greatest length.
On the surface it would seem a longer trailer would be harder to maneuver, however I found the launching process much easier.
I asked my Teamster friend who explained that making the trailer longer actually makes my 17 foot long Ford F150 shorter. There is a good reason why those 18 wheelers have tractors as short as possible and why most trailers have moveable wheels. The relationship between tow vehicle length and the length of the trailer determines the turning radius. A tow vehicle shorter than the trailer makes the rig easier to maneuver.
What a concept!
