got the 10 here as well. came with the tubes, and we added the sailing rig later. it's almost as stable as a rib
- also have a caribe 9' and love em both. the caribe, though, weighs, like, a million pounds. the WB I can haul aboard by myself (it's a struggle, but doable). No way with the RIB. I have yet to sink one of the WB tubes fully while sailing - it's a great learn-to-sail machine for kids
. very safe. not an impressive performer, especially if you overload it, but with 2 people and 6-12 kts of wind
it's a hoot.
don't think you'll ever get the WB to plane with an OB though. Just for fun I dropped a 9.9 on the back (nearly sank it) and opened her up... no plane at all... just plowing water. The bottom went kinda funky shaped and I was definitely pushing the structure beyond intended loads.
the WB is a wonderfully capacious, relatively dry and very safe utility dinghy. add the tubes and sailing rig and if you can still afford to take time off from work (they ain't cheap) then you'll have a very nice little dinghy/cruising machine. a 4 hp ob drives it along very nicely even when fully loaded.
