I think my boat is built pretty much that way. There is no rule that the degree of rounding or sharpness has to be exactly the same at every measurement station. Contact Tom Lathrop for his thoughts as Marvin Spencer built my boat pretty much as directed by Lathrop. Allen Chauvenet

:: It does make a difference.

:: I always rounded the chines as much as the class allows
:: from the bow all the way back to where the maximum beam
:: breaks to curve back to the transom. Then it is quickly
:: fared in to the sharpest I can make it. The transom,
:: too, is sharpened, as is the topsides/transom junction
:: up about three or four inches avovd the chine.

:: The difference is especially noticed when planing. Old
:: #645 was the first one that I know of that used this
:: method. Dennis Snell's boat was always the fastest on
:: reaches in a breeze.....until everybody else learned his
:: secret.

:: :: I am building a new Windmill, Lathrop method. The boat
:: :: is out of the mold and I am getting ready to glass the
:: :: bottom.
::
:: :: Should the chines be as sharp as possible or rounded to
:: :: a 5/8" max radus as allowed in the plans. I don't think
:: :: you would round them on a planing boat, I know this from
:: :: power boats. Maybe rounding near the bow so it cuts
:: :: through the water better.

:: :: Let me hear from some of you winning hull tuners.
