Yet it hasn't been addressed by anyone in the primary phase of boat design, other than Bill Roberts. His Supercat and ARC catamarans are the only ones, that I am aware of, that build a large enough mast section to provide sufficient buoyancy to keep the boat from going turtle in all but the most extreme circumstances, this is not by accident …but by design..
Awww, please that is just nonsense.
Other designs with the same mast bouyancy characteristics :
All the Taipans (4.9's, 5.7's and even the F16's)
There is no way you can turtle a modern A-cat.
All F16's with the superwing mast have the same volumenious mast sections.
I seem the remember I-20's were pretty turtle resistant as well.
I'm sure a few others can add design to this listing.
This problem of turtling is a well know issue. Why hasn't anyone else followed suite.
The question is more why you think that others DIDN'T. You must not believe everything Bill R. says. In this case Bill was talking nonsense when he claimed no other designer ever took this into account.

Yes you have the Hobie Bob, but that is nothing but an awkward band aid that hurts (or is perceived to hurt) performance. Why not adapt this simple solution to a potentially horrific problem. The increase in mast section size never seems to slow down Bill or Eric on the race course.
