I'm curious as to why, with a boat that long (nice boat, too, must
fly through the flat water) you chose not to put the rear rack on
the back mounting holes. Maybe the ****pit coaming wouldn't clear
the roof due to the curves? But it might be a real candidate for 'Hully
Rollers' to make loading easy if you had the bar all the way back.
My set-up for shorter boats is
here.
Even with just saddles, loading is easy from the back. We can carry upright
or inverted, depending on distance and speed.
