Hilly - The 10'6" Son Of Bombora is 28 1/2" wide and the Baby Bomb 10'0" is 28". From what I'm seeing I'd say the 10'6" would be the one suited to bigger guys.
Maroubra SUP - The waves are in Maui and it's Connor Baxter.
Logman - Yes, they will both be big wave boards, for different size people and different size big waves. Jimmy already has a 12'0" gun called The Bombora for the top end stuff. It was the first production big wave gun in the world. Check picture of it below. Will see if I can dig up some surf shots of it in a sec.
These are more semi-guns that fill the gap in your quiver between your everyday surf SUP and the mondo days big wave gun.
Cheers,
