[Rhodes22-list] Deck thickness

[Jay Friedland]

Folks,
Got the deck hardware for the UPS in advance to install. Doyle includes 
a Wichard watertight U-bolt for the furler mounting, but it only has 1" 
of threads. As my boat is in NC, does anyone know the actual/nominal 
thickness of the deck in front of the vent? Also, is there any 
preferred orientation of the U-bolt to minimize load, with the 
centerline or across? Any other mounting recommendations are 
appreciated.Thanks,
Jay
