I just bought an AB Inflatable RIB. Took it home and found the slope or difference between a level line from starboard tube to port tube when fully inflated is 31.75mm. The manufacturer says this is common. To me it looks a bit twisted or lop-sided. I realize some variation is inevitable, but when the boat looks odd...well it must be! Anyone have some experience with this?
How are you measuring the boat? In the water? On a trailer?
The roll of the hull will be affected in the water by weight distribution in the hull. On a trailer, how the hull sits on the bunks or rollers for that particular loading will have an affect. Tube to tube will be affected to some degree by inflation pressures of the various compartments.
Use a bubble level on the deck and make sure that's level, then remeasure the tube to tube difference.
31.7mm is a tad over an inch? Not really all that much in the real world...
