The 41.1 is a much different boat from a Bristol 40. None of them are comparable to a J-boat, the 41.1 is just a different design brief - much heavier, very seakindly. Much better tankage and comfy offshore. My neighbor owns what has to be the worlds best 41.1, and it's really a nice boat that sails well.
The Sabre's are terrifically well built boats, and will be a little roomier than the Bristol. If your choice is between these two, you've set yourself up for happiness, as they are both good boats.
Let's see - J36 - 30 gallons water, 20 gals fuel
Sabre 42 - 120 gal wtr, 50 gal fuel
Bristol 41.2 150 gal wtr, 100 gals fuel
Not really comparable, as the Bristol and Sabre are actual cruising boats, not a weekender.
I really wasn't aware that the Bristols had such large fuel capacities. I do know that some of them are beautifully finished and well maintained, and that 4-1/2" draft would be attractive in the Bahamas.
PHRF NE base for the Bristol is 114-120, depending on rig, for the Sabre 42-CB - PHRF 108, so a little quicker.
PHRF of the old Bristol 40 is 168, for a J36 PHRF rating is 84. If you didn't pass him like he was standing still, you should be embarrassed. That's like a jock picking on a geek in the schoolyard
