Re: chine walking stratos please help
Do you have adequate trim range now now? Have you found where your theoretical zero trim angle is? If you can run at that (zero trim), or positive from that at speed, bow lift is no issue, unless you're plowing. Anything less, at speed, is counter productive. Can you run now (with your current prop) @ wide open at max rpms with the load that you will generally carry, at 0 trim plus? If your motor is not creating a drag spray (set too low) or ventilating improperly (set too high), I would be safe in assuming that there is not much that can be done and no need to think about changing props if yours is in good shape and you are able to accomplish the above. A prop cannot change ?chine walk?. "Chine walk" is the phenomenon that any boat at speed will experience as it cuts at list and grabs the water. Some are more susceptible than others to do so particularly a hard chine designed hull. Every boat has a chine which is simply the transition between the sides and the bottom. Every maker has his own design....hard to soft. At high speed, the violent list port to starboard from wind, water current, boat wake or any other minor disturbance can be fatal. If intermittent ?chine walk? can be corrected at all, it must be done by a skilled driver.
