SUP widepoints

General Discussion
1

I did some digging and was unable to turn up much information on the placement of the widepoint

in a SUP design.

It seems logical to place it at or slightly aft of the the feet…basically right at center, to maximize

the width at the balance point to stabilize the board. I checked out my neighbor’s board tonight and

his is about 1’ forward of center.

The recurring theme when talking to builders and riders is that you tend to grow out of your board

pretty quickly, so I’m trying to come up with something a little shorter and a little more narrow than

what my first inclination tells me.

This is 10’6", coming out of an American Blanks 11’ PLB the plan is to take the length out of the nose

flip and then skim some foam off the bottom to flatten the rocker.

I want to leave the board at least 4 1/2" thick through the heart of it.

I’m trying to balance near-shore distance paddling…for summer flat spells, with some outline curves

that will play well in the local beach break…eg. the pulled in nose and tail.

Should I have built some more ‘straight rail’ through the middle for trim/stability?

I’m 6’1" and 250lbs once you account for my hair, makeup and jewelry.

All of the attachments are outline only, the rail/foil is not modified or governed by the file, just the

outline will be extracted from these.

011b_2.brd is the most aggressive…10’6 x 29" with pulled nose and tail

011a_3.brd is the 11’ x 30 version

011_2.brd is a ‘fuller’ template…I think it’s probably overkill

I’m trying to convince myself that 011b_2.brd could be the one as long as I keep the volume carried

out to the rails and lots of overall thickness…just curious what other folks think.

The current plan of attack is a relatively low rocker with forward vee/belly to cut through chop,

flat through the feet to panel vee through the fins for better rail to rail in the back for when

I get totally radical shredding the gnar, etc.

biuld one wrong quick.

your dreamworld guesses

will colide with earth/water

soon enough.The abrupt stop

will be the board’s fault,

not training and tecquinke.

dont make it wide enough

dont make it long enough

dont make it stable enough

dont make it light enough

make it turn slow

make it a nose rider or not-that will be wrong.

make the wide oint variable

removable velcro rails

steve gaines says that it!

glur on some rub rails outa

garden hose

don long says that

all the great revolutionaaries

start out makin some spare takes.

oh yeah dont make it thick enough.

best idea yet.

some skinny kid will love you

for the cool board…

…ambrose…

You are going to need a board with training wheels to start.My 1st attempt was way to squirrelly to paddle but surfed great.

Try you neighbors-friends -sisters any bodies board and move on from there.

Think fat stable boat to stand on and scale up a normal longboard with the rest of your core shaping ideas.It all works up in + size boards and in a newer sport your opinion is just as valid as most.

I wasn’t able to open your file do to the computer I’m using, but to answer some of your questions… I am 6’5" 220lbs and started out on a 10’6"x29x4.25 with the wide point near center as I recall. I pulled in the nose and tail and had near parallel rails through the middle with vee in the bottom third. The board floats and paddles/surfs well, but is by no means going to win a distance paddling contest. I think what Ambrose is saying is not to limit yourself to what other people say. I have had a couple of discussions with him on that very topic at his place in Kapaa. If you have seen any of his post, his boards are far from cookie cutter. I believe he has some that are 14’x31"x5" or bigger. I saw a friend of his riding a 7’6" sup with plans to go to a 6’10". The one thing that is probably most important is that you carry the volume out to the rails.

This will prevent fatigue and aid in the floatability of the board. I think the SUP/SUB is still evolving and what you see everyone riding today might not be the same tomorrow. Most importantly have fun buiding it. Aloha.
