with a heavier one. Useful to know for owners seeing the light & converting to junk rig
Was it on Voss or Slocum who hoisted a bag of potatoes up the mast?
Yes, when mass is distributed more evenly rather than concentrated at the lower extremity, a boat will have a slower roll. BUT it will be a deeper / longer lasting roll too - a boat that rolls to 30 degrees each way for twenty minutes after that bloody tugboat passed you by is a hard place to live in.
I like stiff boats: cats and racers with light hulls/rigs and 50% ballast - yes, they are a bit jerky BUT they settle down nearly as soon as that tug wave rolls away.
Another aspect is that such low ballast / heavy hull configs tend to give false impression of boat's stability in rough seas. They may show gentle motion and lull the crew into a 'she is doing just fine' mode. Then one wave is bigger than others and that's the end of the story. BUT, off course, this is an extreme case, not likely to happen in any professionally designed, professionally built boat.
