excessive pounding in choppy water

JohnH1946JohnH1946 USAMember Posts: 3
I recently purchased a 2019 hurricane SS218 OB. Is there a recommended speed for operation to
reduce the pounding when the water is rough. Also, ant suggested engine trim levels? I operate the boat only in fresh water but when the lake is active the ride can be at times uncomfortable
Thanks

    The SS 218 model has a 12.5 degree deadrise hull, the lowest degree Hurricane makes (as does my SD 237).  Some models have up to a 16 degree deadrise (the newer SD 2690 OB has a 19 degree).  Higher deadrise numbers usually dictates a hull that cuts through the water easier, but takes longer to get on plane.  On the plus side, your model should give you better hole shot and quicker planing, shallower cruising depth and usually can maintain a lower cruising speed while on plane.  Unfortunately, whatever the water surface conditions are often dictates the ride since the boat has a shallow draft.  I will tell you that weight and length does have a softening effect on this hull design.  For example the  23' SD 237 has a vastly improved ride over say an 18' SD 187 due to additional length and weight.  Balancing out the weight and keeping the fuel tank mostly full can sometimes help the ride.  Cruise at the lowest speed where the boat feels the most comfortable and is still staying on plane.
