Hey Brooko,
literage puts thickness and width and length on an even playing field.
Reasonably informed judgements may be inferred by volume without seeing and handling or paddling the board. The volume concept is a very good way of fine tuning your boards.

10' x 28" x 4" and a pic tells you not much at all.
10' x 28" x 4" and a pic might look identical to the above board, but this ones rail is finer and the nose is thinner and the tail is slightly narrower.

Will they float the same? The pics show them to be very similar, volume sorts out this problem. The first one is 140 liters the second one is 130 liters.

Sorry this is the other screen shot the original design.

Here are a few more images of the white 260 at the shape stage.
All my boards are for sale at any time just check the for sale in paddle surfing seabreeze, pm or call me for more info, check my bio.

Here some more images, foam fins being made and the white 260 glassed,
the image was taken from the mezzanine.






I'm pleased you liked the red 9'0 Tha Dogman, thanks for the report.

Rod

I have to translate back to imperial all the time Ben, I've been using metric for 20yrs. It started when I first used the first pc program for board design, that was called DAT deadly accurate templates. 9'0 is easier to say than 9foot.
Good fun building your own boards?

A few images of PVC foam fins and showing the position of quad fins on the new 8'6

These are the fins glassed and trimmed to shape, the tab is for holding while foiling


The quad setup on the new board, positioned and tacked on

This shows the deckpad template on the deck of the board ready to be traced out so that masking tape can be placed around the drawn template so that resin does not go here.

The board with the filler or sanding coat applied. you can see the masking tape in place under the board. The fins have been pre sanded before filler coating, this saves a lot of time with set fin quads and gives you a smoother plane between the fins.

All of them, except the latest molded blanks from USA which are available in higher densities than you can get in Aus.

Ah, funny story. I'm enjoying this site. I just hopped over from my beloved downwind racers for a bit of a squiz of what this boardbumps fella was up to since he paid a nice compliment on one of my posts. I started reading all this talk of board volumes and was just about to ask how you were coming up with these figures. Boards are way complex shapes, it's not straight forward like a cube or even a sphere. I was about to tell you I used to know this bloke named Rod Hocker who reckoned he had a formula for board volumes when I scrolled a little further and lookout it's you!!! Don't know if you remember me, coz geez we've breathed some fumes over the years but in 85 I used to see you at Fleckys' a bit, I was upstairs at Alohas and you were heading up Shanes epoxy division while I was workin' on the same project in our place! Remember the nightmares from that shonky SP 115 system from the states? Ah, memories. Anyway good to see you're still kickin, still thinkin and haven't lost the passion!! I haven't been down that way for ages and am probably due, I'll get in touch next time I'm coming past and pop in to say g'day and check out what you're up to. Cheers, Stuey Campbell

Great stuff Rod thanks for all the pics and info , love your fins.
I'll post some pics of my double bend timber paddle next week.

These images are of how I apply the non skid to the nose of my SUPA boards

This image shows the nose masked out ready for the peel ply non skid to be applied. Using this method no wax is needed on the board.


This image is a closeup of the peel ply taped into place before the resin is applied.


The resin has been added to the fabric


Closeup of the resin applied to the fabric


I am starting to remove the peel ply after the resin has gelled. The trick here is to leave the resin as long as possible before removing the fabric, too short a time and the resin settles and or comes away with the fabric and is too smooth, too long a period and the fabric does not want o be removed from the resin.

The board has been sanded in this image, it also shows the quad setup. The 8'6 is in the spray bay waiting for the clear spray coat


The clear spray coat has been applied in this image


The next sequence will be of how I put the hand hold into the deck of the board and how I make my own EVA deck pad and glue it down. That will be later in the week, today I'm at home with one of the kids off sick and the wind is cranking from the NNE.

I'll be away next week it is our annual Oct hol week away at Soth west rocks. If your in the area drop in for a demo paddle, we stay over at the jail, right out at the end under the jail, look for the big silver tarp

Rod

Casso, great spot for the kids. The nne gets in for wind with an easy kite launch if the tide is low when the wind is crankin. A big south swell is supposed to wrap into the bay best of all. Its always windy where we camp, extra pegs on the guy ropes to hold the tarp. The wind has started with a vengence in Coffs, this is about the 7th black NNE already.

Rod

hi rod

wind is crankin

my band is playing at the pub at south west rocks on saturday night

the Airbourne Blues Virus

dont think we'll be able to surf as a few of the local crew are keen to party on

occupational hazard

Hey Dogman, this coming Saturday? If so I might be in a bit of trouble.

Just been looking at your pics, trying to figure them out, Jakes is looking good.
