The original Lis fish(70-73) was 5'-0",5'-5"(kneeboard) had a very slight belly thru out the bottom with the exception of the last bit of tail tips,and a mild but noticable concave in the deck.
The stand-ups varied in length,but the bottoms had a belly-ed nose that faded into a mild (un-noticable by an untrained eye)mono concave that extended to the fins............anything past the fins to the tail tips is flat bottom.
Yes,on the old schools a nice soft,full boxed rail , just about the thickness of the board or a low, downed rail with a soft tucked edge. both rail types go sharp/hard edge in the last foot or so.................his newer stuff has come more to time.Herb
Interesting...
Really been having fish schooling in my head lately.
Been using USB 6-5 A W/ -1/2" N. for 5-8.
That's lots of foam to fool around with
paddles and glides over the flats.
Totally flat with tucked edge (GG).
Seen some impressive FISH stuff lately.
Just thinkin' this might be a stoke factor for this oldphart.
But channels????

I would rather be someone's shot of whiskey, than everyone's cup of tea.
I have a 66-page pdf of a 1977 design book that actually has a breakdown on the bottom, rail banks at 12" increments and the template, foil and keel placement for a Lis 5-5 fish.
Flat bottom with a very subtle 3" wide chine. The chine is 3/16" at both ends and 1 touch more than 1/4" in the middle.
I've used the flat bottom + subtle chine on several different types of boards in the wider widths and it's always worked out. I think that for the wide boards that don't need any additional lift in the bottom contour the flat+chine provides a very predictable feel of control, whereas adding concaves to wide boards only adds drama to their handling characteristics.
YMMV
Gdaddy, I guess I'm reviving a very old thread but I'm always on here poking around the archives trying to learn. If you still have it, I'd be really grateful to check out the PDF of the 1977 design book you mentioned.
I'm working on a 6'3 Lis Type fish based off a Mabile template I made from my favorite board. That board is flat all the way through with double foiled keels and goes great.
Glad I came across this thread because I'd given into the overshaping bug and scrubbed a very faint double concave into the board from the fins back, but I'm thinking I'll flatten it back out now.
Hey gdaddy I'm interested in the chine and flat bottom on a wide board in making. Does the chine carry the same width the whole length or taper in from the nose? Do you carry it right out through the harder rail at the tail? Cheers

Bring it on !
Tucked all the way through ? How thick ?
