The northbay is a very attractive s&g kayak. 20"x18'3"(3" if you don't soften the pencil tip ends).
It has a similar keel line as the Chesapeake series, very slightly rockered centersection with a very slight raise in the ends where the bottom panels narrow significantly. The coaming can be short or long but in the short version the deck beam will sit right at ones kneecap requireing adequate minicell protection. For this 5'9" person with size 11 feet the footroom is inadequate. The displacement is not small so a small person who feels comfortable in the cockpit will be small for the kayak and a normal sized adult who can sink it in the water will be cramped.
Performance wise it has a constant weathercocking that the lack of rocker, slab sides and tight bow prevent paddler skill to compensate for. On small waves from the stern the sharp entry will stick allowing the bow to dig and bring the kayak into a broach easily.
The slab sides and lack of rocker remove any predictable secondary one might desire for control in waves (especially noticable for waves off the stern) or to provide a responsive hull for lean/sweeps. It is a fast hull.
The aft deck structure using underdeck carlins adds unnecessary weight and intrudes on storage space.
One could rate it anywhere from 1-10 depending on what one expects from a kayak.
