I have sold a few Avanti's and Boss's through my shop.
Both of these boards will suit your requirements well, the Sumo is 40" wide which is a little hard to comprehend.
We also sell Whoppers and have them in our SUP school fleet, as The Whopper is only 171 litres I would be going for a new board over 200 litres in volume.
