If factory purchased does a boat come with the outboard offset ?
What are the benefits ?
My Humber 5.3 was factory fitted with a Merc 90 4str. offset 2 inches to starboard. I believe the idea is to counteract the propeller torque which, when planing, will tend to make the boat heel to port.
With one or two people aboard it could start to chine walk beyond 35 knots (max 39). In calm water (and I wouldn't want to go that fast in lumpy water) I found harsh, WOT acceleration would initiate a chine walk. With gradual acceleration it remained stable.
The Merc was replaced by a Honda 90, which is around 30 kg lighter. It took me a season to sort out the fore and aft gear stowage and get the weight distribution right so I got the same performance out of the boat. With less weight on the transom, she feels more stable flat out too. Only chine walked once since, again as a result of harsh acceleration at near 40 knots.
Of course, I know it's not a Searider.
