This is how we build a swing tongue:
Level straight down from end of boat winch post so swing away parts dont extend past the plane of the winch/post assembly when completed.
Cut tongue with either saw zall or angle grinder with cut off blade making sure to remove wiring or hold to 1 side...
Purchased this boat mainly for the windshield it's not the original it was updated at some point, going to install it on my 1988 Super Sport 18 that we rebuilt this last summer, and use the windshield off it on this one.
