What makes a board carry bigger sails?
What exactly makes a board carry bigger sails?
Example: same volume, but a hugh difference in recommended max. sail size:
- Kombat: 96L, 237cm, 62cm -> max. sail 6.5
- iSonic: 96L, 244cm, 59cm -> max. sail 7.8
Ok, what's obvious: Kombat has only US Box and is therefore limited regarding fin size. But if the Kombat had a Powerbox, what attributes are deciding the max. sail size? (Of course: the Kombat wouldn't be a freestyle-wave board anymore with 7.8 ...)
