I had a 2008 GW 305 express with 300 G2 evinrudes. If I had to do it again I would grab a BW 315 with the new hull design and cabin config. I would do the canvas back with 350 verados. I have a family of 4 with a 10 and 7 year old. The sight lines and access to the cuddy is down the middle of the boat, so when yer in the cuddy you can see direct to the transom. The 300 marlin isn’t quite as airy feeling. The solid windscreen is waaay better on the 315. The Grady canvas above the windscreen is ok, but unless yer gonna actually take it off in the summer it just gets in your way of good visibility. I’m not a fan of ray marine electronics but whatever(ford chev dodge), the back deck feels bigger than the marlin. They’re likely the same size, but for whatever reason the 315 just felt like you had more space.
Get a diesel heater(D4 or equivalent).
The ride is pretty much identical as with the fuel economy. Resale will be about the same too.
I prefer the white of the BW vs the off white of the GW hull colours. Servicing the boat might be a touch easier in van with M&P there for the 315, but I hear great things about parksville boathouse for GW.
Best of luck, and you can’t go wrong with either brand!
