>>1399154that one is not my style but this OP is right custom made high end boats in general are the ultimate outdoorsmen luxury item. as far as gear there is a split between people who seek high end antique items (Corsican knife) and those who are looking for the hottest tech gear (Scarpa boots)
the real split is more at the activity level. wicked rich people do specialty activities with a real high barrier to entry. Kite Surfing, Paragliding, Helisking - in more exotic locations.
