I am working on a template for a 6.0 Lis fish and have scaled up a Lis fish template using the Ratio method or true scale method. The width would be at 23 inches wide. The question I have is: How wide is to wide? What difference would this make in the performance?
I think there’s a problem with this scaling method, such that volume increases faster than linear dimensions. For example, a circle with a radius of 5 units has an area of about 78.5 sq units, whereas a circle with a radius of 10 (double that of the first circle) has an area of about 314. So, a linear dimension doubled results in quadruple the area. The same thing happens with surfboard volume when you scale up dimensions.
Not to be too sarcastic but running out of foam is too wide.
There are no rules. Give it a try. Template it and see how it looks and feels then decide if you should change it.
The comparison ,for me, would be when I go from an 18 3/4 " wide thruster with nose kick to a flat 23" wide kneeboard.
Standing on both, I notice the delay in response in cutbacks, re-entries [‘off the lips’], and bottom turns.
Other than that, the wider board is nice to paddle [catches waves easier], planes and trims well, and FEELS faster [flatter rocker]. Just because the nose is a LOT wider, I have to watch catctching that edge up there… something I noticed on a waist high day, trying to do a forehand cuttie.
I guess, then , that the short answer to the above is : -
it depends on the board you mainly rode before. [The transition fron narrow, thin thrusters is not always easy straight away!]
And , also, what you want to do in your surfing…
…if you were / are a “break the fins free on every turn”, and “air to reverse” guy, expect something DIFFERENT when you hop on a fish !!
I agree with the above comment about " cut it out and see if you like how it feels / looks ". [If you don’t , then NARROW it !]
The fish I normally ride is 5’ 11 x 20" x 2 1/2 " 15"n , 15" tail, 9 1/2" pod tip to tip. [SOME may perhaps call that a wide swallow tail… the Lis’s, I’ve noticed, are straighter railed near the back few feet of the board, and wider pod tip to tip measurements].
I am 5’10 and weigh 140-145lbs…[What size are you, because it’s relative to your size too, what size / width ‘fish’ will feel best for YOU !]
okay, I hope this has helped you …

Not to be too sarcastic but running out of foam is too wide.
That was just classic!
Tried a buds 5’6" x 22 Lis fish.
He, 5’8 and 180, with long arms, short legs, super long torso loved that board.
Me, at 5’10" and 155, with short arms and torso, kept hitting my bicept on the WP rail, or just in front of, and couldn’t quite paddle it as fast as another buds 6’8" x 18.5.
Depends, how you’re built, what you like, what size waves ridden.
You must be a giant, that 5’6" Lis fish floated the tops of my legs dry, just like my 7’9" BIC!
The blank I have and was planing on using is a 6’9A and is just wide enough to net a 23 inch wide fish.
I am 6’1’’ and weigh 205 lbs… I ride everything from high performance shortboards to fish, and longboards, depending on the conditions so the transition to a traditional fish should not be to dramatic. I have rode several fish in the 21 inch wide range but was just wondering if going 23 inches wide may be to much, and how it may effect the performance. Has anyone out there rode a fish this wide? Did it slide out too much in steep conditions, etc?
Well, at 205lbs. and running 5.5" x 9" keels, you should be able to hold in pretty well.
Smaller fins will slide for sure.
You can soften the edges where you stand to ensure more holding power, add some volume to the rail peak for more water wrap, throw in some V to lessen the pressure needed to bank the board at speed, or even slightly increase the tail rocker for more holding power…if you want to, or think you need more positive reactions.
It totally depends on the waves you are surfing, how positive YOUR surfing is, and how used to a 18.5" tail you are.
Nice to have +11 feet also, to go rail to rail with the wide tail boards.
Hi All
i did the same - scaled the lish fish up to a 6’2 and got a 69a blank - but the template will not fit on. The wide point to pins is straighter than the blank so you run out of foam.
i still made a nice fish (6’1 by 22 1/2 by 3") from the template, looks tiny to me but it has loads of float, and today i will finally get to sand it and hopefully tomorrow get to ride it!
i looked at bigger blanks and the best i could find was a (i think) the 7’10R which will allow you to cut a bit off both ends and use the flater, thicker mid section.
i have not tried this yet, if anyone has let me know or suggest a better clark blank.
i hope this help
as ever - keen to learn…
Keen - How 'bout a 7’9" E? That’s wide enough, plus the rocker is flatter than the 7’10" R. I made my first board with one - lots of room for “thickness errors” too…
-Matt.
Hi Msacht
Thanks - i will take a look at the 79e
as ever
keen to learn…
icarus - I’m 225 lbs and 6’ 2" and recently made myself a fish from the 6 9 A with the following dimensions: 6 2 x 23 x 2" thick (tail - 16.5" , nose 12" wide.) The board’s got a bum tail - ie a swallow tail with rounded tips.
board rides amazingly well in sub 3 ft mush - is ok in hollow sub 3 ft mush but is horrible in 3ft plus of any description - it’s just too fast and skaty.
I’m gonna make another - this time a bit thicker - 2 1/2 - as paddling the thing around takes a herculean effort. I love the board but it’s purely for those desperate tiny summer swells - longboarding just ain’t my thing (I give myself another 6 yrs on shorter stuff before I grow a moustache, let my middle age spread advance and start hogging everyting on a 10 footer).
Yep 23 " is ok at your weight - but don’t expect it to have much range.
Not to be too sarcastic but running out of foam is too wide.
Rob this is a classic statement. So true.
You might take a look at the 7 3 becker as a fish blank. Mike
The only thing I would think of is sticking in rail to rail transitions…maybe some vee??? Make it …then let us know how she flies…
Thanks everyone I am going to cut out the template and see how she looks. I will let you know how it goes.
Thans again.
I may be late to contribute but in my book 30 inches is too wide.n case this may help…ambrose …hard to carry
While on the topic of wide boards: does anyone make board bags/cases wide enough for the current short&wide board craze? Back in the early/mid 90s when I bought an Al Merrick twin finner, I couldn’t find a board bag it’d fit in and it was only 20.25"! It got shipped to me in a box but after that, I had to just leave it in Japan and when I travelled I could only bring my 6’6" thruster because I couldn’t get the damn twinner into a travel bag. How about these days?
