Man-this exercise routine sounds pretty good for an 80 year old-i'm only 50.
Yep-this is what I'm thinking. I'm curious as to why you are choosing the 6'8 length.
Looks like just what I want, although I'm shaping it in PU. Looks like a pretty wide nose-it doesn't hang up when it gets hollow?
maybe something like this…
its 6’6" x 20" x 2 5/8"…but you would adjust volume to suit depending on fitness and breaks surfed and how greedy you are for waves…
fullish planshape without going too far and creating a board that wont get on rail easily…

sorry, dble post for some reason…
feel free to ignore most of this. numbers are not my strong point
a board your hight thats 3 inches thick will surf better then one 8 inches longer and thinner ( in anything up to head and half )
3 to 4 inches taller than you for DOH
22 by 3 inches thick i think has close to 6 liters more volume then 20 by 2 3/4
six liters will create favourable bouyancy and float an extra 18 kilo of weight
so an 75 kilo pro is cruizin on 25 liters everyone else of above average ability need 33 ish
an old dude would need 37 to 38
a 100 kilo old dude wants over 40 liters in the shortest board possible for hotdog surfing so as not to surf/stall off the tail in less then stella waves
im 40 and 95 kilos and 6 foot 3 . wouldnt surf a board over 6 5 unless it was maxing and prefer nothing over my hight unless its getting over head and half and solid.
a 22 wide board rides the barrel fine. i surf rivermouths and get tubed all the time on wide boards
we cant be old and have a thin board its a sad fact of life. or we can join the old grumpy X gurus who have turned into speedbumps and spectators. somethings we have to give up and sensitivity and thin rails is one of them. so our surfing changes. lines get longer, board gets speed from trim rather then pumping. and we dont fluff around with a hack unless its well overhead . and you really hack that shit. not little flicky tail turns in waist high surf. but the real full rail shit and it dont matter if the rail is fat cuz we are fat and we can still bury that shit. ride the outline forward and use a rounded pin, somehting like that webber you posted is perfect but take it out to 22 and 3 thick and knock 4 inches off the length. get sum simon anderson fcs for it and you are laughing your way throu the pack ( in fact people will start complaining about you catching to many waves)
hey greg i cant take credit for that stuff mate. i learnt it from bert and greg et al

This pretty much sums up my conclusions of the modern potato chip performance shortboard. These boards seem to be made for youngsters (16-25ish) that way probably around 75 kilos. So, if a 95 kilo person adds width and/or thickness, doesn't this equate to the same ride? Physics would seem to dictate that this is the case.
Also, you guys have given me awesome info and I appreciate it greatly. Before this thread, I didn't know how I wanted to shape this shorty, and now I've narrowed it down to 6'2 to 6'8 and 20-22" wide.
By the way, I just watched "Many Classic Moments" on Fuel TV last night. Those guys had some thick ass boards and they sure were able to lay it on rail pretty hard. Although most of it was north shore, they also ripped em in the smaller stuff.

Looks like you put the wide point a little forward?

So, if I scale the nose and tail width proportionally to the increase in width, I would have the following dims: 6'3 x 13 7/8n x 22 x 16.5t x 3, which seems like a pretty wide tail. Sound ok to you?
Wider, thicker = fun, fun, fun!
You’ll wish you did it sooner, I promise!
I put a bit of a down rail on mine to offset the thickness of the rail…least that was my original non-scientific approach and it worked so that’s what I do. Works great for me!
Gonna be fifty this August, 6’4" and a jelly donut away from 240 lbs.
I’ll let the numbers experts chime in on your dims…what I basically do is scale up proportionally the shapes I like. But I’ve always ridden boards a little longer…just my preference.
hey dccasey i would pull the tail on that to under 15 inches. and you can maintain the asthetic of the curves by moving the wide point forward
your two choices from an asthetic point of view is to have a wide tail and widepoint further back . or pull the taill in and move the widepoint forward.
i like about 14 1/2 to 14 3/4 in the tail. with about 2 3/4 flipped tail rocker width im currently riding 21 7/8 i thnk. i much prefer pulled tails with the fins setback to 3 .
a good thickness is about 2 3/4 to 3 inches thick. but make the tail thinner like a normal shortboard. dont leave the tail clunky
widepoint works up to 3 inches forward
deep single concavce
keep volume under chest . dont thin it out. think 80s thruster or 70s single fin. you do notice the swingweight. but its not a bad thing imo. gives you trim speed and major paddle power
Very good advice from Paul Cannon. I would like to give my take on the tail: you can keep the wide point in the middle of the board and do a bump in the outline at around 12" up from the tail and use a smaller round pin template behind the bump, that way you can keep some width in the tail yet finish it off a bit more pulled in for the hollow waves you intend to surf on that board. Like Paul said, a tail around 14 1/2" should work fine.
I recently ordered a board from a friend (haven’t found the time to shape my second board myself) but it is intended for overhead Gas Chambers in Puerto Rico (a really gnarly hollow right) so it’s a different wave and board than what you are talking about but yet it’s somewhat similar. Board came out 6’10" x 12"N x 21" x 14"T x 3 1/8" Thick, WP center and a bump at around 12" up from the tail ending in a nice sharp round pin. It’s a 3 fin thruster and as soon as I get it I will post pictures, should be glassed by this week. For reference I am 5’10" 220-225 lbs lots of muscle and a beer belly jejeje.

I think I'll go this route. How does 2" thick at 12 up, 1.5" at 6" up and .5 inch at the tip of the tail sound? Hmmm, I think I'll have to take my 7'0A blank back and get something a little more close tolerance. Thinning out a 6'4 like this would mean seriously mowing down the deck to thin it out.
D-Dog;
Here are the pics. The first is a 7’0 wide point back 3" that I surfed in the Mentawaii’s 2 yrs ago and is still there and going strong. (Hollow, hollow, hollow) The second is my personal 6’8 that I surfed in O’side recently and had a fair amount of fun on. 
It is wide point back 2". The third is a 6’6" wide boy at 21" + that was shaped for French beachies and is presently on tour aboard a USMarine warship. (Long story, but wide point back 2") All these boards work well in O’side type waves. I will send you the Shape 3D file that you can tweek until you get what you want. I would suggest that if you are looking at a US Blanks board you use the 6’8P which is close tolerance to what the design needs. Just skin lightly the deck and adjust the rocker from the bottom. You might end up with a 6’7" if you measure from the deck. (I don’t) Also, I really like Foam Corps yellow foam and can’t front them enough. It is light, crisp & strong. They have a 6’8 SBP blank and if you ask for it in the natural rocker it will suit your needs to a T!! I really like their foam in this blank. It nets out a 6’8 with a decent 4 +4oz glass job in the 5 lb. range. Not bad for an old man’s shortboard! Anyway, that’s just my 2C…

Sorry, order posted wrong. Fat Boy Marine first, mine second,
Mentawaiis third. LOL
that blank might be ok tho. you might have to use a larger blank to get the rocker you need. i generally use fish blanks and do ten to overshape them on the nose a bit but you dont put your foot there anyway right. ill go measure what i just shaped its for up to doh and is a refined and shorter version of my big wave board (doh++)
nice boards surfteach i would look at something like for big waves!
Thanks Paul!
The Mentawaii's board worked on shoulder high to 2x OH Greenbush. The guy that owns it now surfs it at Macca's and some secret lefts when it rifles (LOL). Anyway, when I win the lotto, I'll send you a check so you can join us on a boat trip and leave the kids at home! I'm getting fatter by the day here in Cali. One day you will visit? Hope all is well, best always,

hey tonylion i like the idea of the bump to pull the tail and keep widepoint center. i might start playing with concept more. like berts S tail
anyway i measure dis one i just done. mind you i did make is slightly narrower for smaller waves bros
nose is 14 1/4 wide at 2 inches thick
widepoint is 21 3/8 at 3 1/4 inches thick
tail 14 5/8 at 2 inches thick
length is 6 3 to 6 4ish . around my hight. not that critical
deck is pretty domed so as to get a reasonable thickness rail
concave is about 5 mm deep and goes right out the ass end (depth gets less at the nose and tail) and start at about a foot off the nose
widepoint is somewhere forward of center. i dont know exactly maybe 2 inches or more id have to check thru the aku files i got
nose entry is around an 1nch 1/4 maximum
wrt tail rocker … this is all personal and has a big effect… also highly opinionated …so this is IMO …tail is to your taste but will make or break the board . the more the better as waves get heavier. i like around 2 3/4 on average but play with in relaionship to fin positions and size… so if you like big stiff fins then more tail rocker and if you surf small flexy fins then you can have less tail rocker … flip in the last few inches will loosen the tail and still have good drive from the the larger radius at the 12inch point.
i know that sounds weird but i guess its reall a three stage rocker with flip at both ends
