i thought i read Rob Macks saying he adds some flare to his boats for better stability. Looking over the replica website i saw most all of those boats have varying degrees of flare at the hip.. most but not all..
I'm assuming if you have good flare on the bow and stern then you need less at the hip...maybe a rockered boat relies on flare at the stems more than a less rockered boat.

: What Toni said except to add that flare forward tends to give increased
: boyancy (bow doesn't play submarine in waves) and reduces spray over the
: deck.

: One downside to flare is that it tends to create a hard edge at the hull/deck
: intersection that can make the boat difficult to roll.

: With boat design, everything is a tradeoff.
