Hello DerekL
I have the same issue. My best guess is there's more substantial cabinetry on the Starboard side of the vessel. It used to bug the daylight out of me, but overtime I've brought on board and stowed enough stuff to more or less balance the vessel, at least when both Port and Starboard water tanks are full. You might consider some "sacrificial" weight if it bugs you too...like the 70 lbs of chain stowed in a milk crate in the vacant space under the removable quarter berth cushion (helps balance fore to aft when the forward water tank is full too).
With trial and error you'll sort out stowage to stand up straight. Like where the outboard ends up mounted on the rail, or if the stern anchor is better off the the aft lazarette or next to the outboard mounted on the rail. The alternative is to redesign the cabin layout via sawzall, and frankly our time is better spent sailing. Unbalanced you might notice a half a knot difference on each tack, or you could chalk that up to current and speed overground and keep your eyes on the horizon instead of the knot meter.
Someday that chain will end up on the end of a rode with an anchor attached and I'll have to start all over from the beginning. Starting with where Sweet Sassy M'Lassy sits in the cockpit. In the meantime, "Isn't that whale spout over there? Never mind, just a pelican splashing into the deep."
