With side mounts On a walk around cabin side, they are a” must have” if your fiberglass is thin, as most are there. on mine they really help side to side stability –which is poor without them , even though fore aft is very strong. I have had center bolts back out and drop spacer washers on deck even though were torqued tightly, so I plan on using a stronger version of locktite and maybe a lockwasher in the shim stack. transverse bolt cant be tightened while fore aft bot is in place making periodic check retorque untenable.
