As S/V Mystique implies, dead downwind is usually a poor direction in which to travel and not a shortfall with a B&R rigged boat unless somebody tries doing long hauls without the proper sails
, something most cruisers wouldn't even think about. Regardless, there are too many racing
boats and world cruising rigged boats with B&R rigs too numerous to list.
I think the real issue is that there are some who just like to criticize, be it hunters, B&R rigs or anything else with which they are unfamiliar or don't have.
I saw too many B&R rigged boats throughout the Pacific when we cruised there years ago to put any credibility to that criticism.
