The wave boards come in 2 styles, the Chopper which is a shorter board usually about 225 ish long and about 58cm wide for the 80 litre, heaps loose and comes as a twin with a swallow tail, being custom you can order different volumes and bottom shape can be tweaked a bit for the rider.
There is also now the Swinger which is a longer board for guys who like a board a bit longer, there 233 ish and similar width to the chopper, the rocker is a bit flatter through the tail and have a round pin tail.. the"Swinger"as the name suggest comes in different options, single, twin, thruster or quad..
The boards are getting alot of influence from surfboards so they shred on waves as waveboard should..
Here is some footage from the 2010 Merimbula classic of Ben Severne (bright red board) killing some waves on the 90 litre Chopper "monkey Board"
