There has been a discussion going on the wave forum about what the limiting factor for speed on these boats.

On my 5.2 sailing solo I always thought the limiting factor was being able to hold the boat down. I have to start spilling air out of the sails long before the lee hull starts to dig in to deep.

But in some posts people have said that their limiting factor is the lee bow diving.

So what is it, does it differ by boat?
