Just got a slab of Pawlownia so I thought of doing a paipo, but looking to do something different…
**Beautiful, "do what you know and don't be slow"**
**Aloha!**
I thought of doing a few hand planes but its the first time Ive had Pawlownia and it speaks to me to do a paipo, but something different with the design.
With other paipos Ive made and ridden I don’t like the minimal nose rocker because it digs too easily and the lack of bouyancy sux when paddling out or getting on a wave or getting thru flat spots or having any visibility when sitting in the lineup or …
I know that’s how paipos are but there’s no harm in trying to change things, if I could I’d like to supercharge a paipo and give it more than 2 inches of nose rocker and add the absolute speed of an inflatable hull.
Hmmmm…
rocker add ed with steaming the wood
in a steam box and add a stringer
to hold the contour from bending,
aka relaxing back to flat.
?s do your design limits include
light glass or just linseed?
add an air chamber for inflatable contact side?
under cowl entry before inflatable chamber?
…ambrose…
wood (lumber) paipos are coolest
because of the simplification of
or minimal design limits
make it a quick
uncomplicated build.
an’a simple wave rider,
ak - primitive …
XPS ‘under cowl’ at nose for 12" then inflatable hull out the tail.
Glass / epoxy / vacuum / CF nose cowl / inflatable hull at minimalist depth…
Natures love on the deck for all to see… But underneath the beauty of a natural deck is the evils of " modern life " …technology, petrochemicals, focussed thought.

go man go!

Here’s a pic of mine I made some out of plywood then spar varnish and some with glitter in them for special effects.I gave some away as gifts.fun stuff when the waves are mushy and a surfboard won’t work.i wish I could afford some Pawlownia:)
Tender Loins Tom, they’re great paipos, nice variation in artwork and colours. What’s your take on the performance of the swallow tail ?
Here’s the EPS nose rocker cowl, inch and a half thick. Will put the rocker in tonite.
Usually I’d glass the bejesus out of everything because experimentals can be unpredictable, but I’m feeling relaxed about this so I’ll build it up first, and then see how I feel.
Brett,
Putting aside your desire for experimemtation, the beauty of a wood board is the simplicity . Nose rocker - not much is needed. A thinned out nose works fine. Low bouyancy, has pros and cons. It’s fun gliding under waves as well as riding them. The capacity to duckdive allows you to sit more in the impact zone as a way to compete with more bouyant craft. Where less bouyancy can be a problem is when there are strong currents and long paddles.
I’ve seen some attempts at spoon-like paipo. An alternate idea is a thin foam base which could be shaped to give you some nose rocker and the tail could be shaped in whatever way you wanted (or how about some foam i-beams glassed over).
Bob
I did the swallow tail mostly for looks also it fits around your belly snug. @ surf foils nice going yourself , are those rail bands on the foams edge ? Keep us posted
Ive tried and tried, its part of my DNA to experiment.
Hi Brett,
Must be nice to get some encouragement from a fellow like Ambrose,a deep thinker to be sure( I think)
I enjoy trying to decifer the meaning of his commentary…
That’s a nice piece of wood…
Pardon the silly question ,But is the foam for the top or bottom?
Speaking of the need to expirament,
this is something I came up with a while ago
It’s a skimboard with some fins bolted on,
I tried clipping it to a ski vest in an attempt to isolate the bouyancy from the planing surface…
I called it the Turtle Belly
Thought it would be a little safer to actually WEAR the bouyancy as opposed to just holding on to it…
It failed mostly because the interface between the vest and board (foil) was just too loose, (but other reasons too)…
I had never heard of paipo boards until you opened my eyes to the wonder that is Swaylocks…
now I wonder how this might work as a paipo board,
It has a lot of rocker which I’m not sure is a good thing or not for something like that…
anyway, always cool to see what you’re up to…
happy shaping…
Dave
Hi Dave, good to see that you save your experiments too ! Give the Turtle Belly a go as a paipo. How’s the foils going ?
The foams for the underside, it will give the board nose rocker and some bouyancy.
Behind that I’m putting in an inflatable hull. I made a few surfmats with hard decks and they rip, speed of a mat but its under complete control. I did the same on a windsurfer, gave it away and can’t get it back from the guy !
The combo of wooden deck, foam nose and surfmat hull is unusual but I’m sure it’ll fly.
I see now, a rigid inflatable, a zodiac for the surf…
Was the entire bottom of the windsurfer a mat?
Using that concept I could see also engineering an frp panel, and building in flex wherever it might be usefull…
How do you plan to attach the board to the surfmat?
concerning my foils, I’m in the process of adding a little x45 carbon to the strut to dampen the twist a little,
but also around the leading edge to prevent delam,I got away without it for a while but one side finally popped loose.
I’m also learning how to use the gopro and trying to figure the best way to mount it to get close up shots of the foils interaction with the water.
I liked the perspective that you had on your video, do you have pictures of that setup?
Brett,
How rigid is the deck of the mat. Could it be folded into a suitcase?
Regarding the foam - deck up or bottom, you could always try another one with the foam up as a spoon.
Bob
Dave, I never thought of it as a Zodiac, I’ll have to name it Aquarius, or Taurus.
The windsurfer had 2 foot of nose and 2 inch wide rail with the inflatable part filling in the rest. The rider said it was as fast as anything else he’d ridden but it was a lot smoother. I can do a drawing if you like. Putting a hard deck on a mat works really well, it doesn’t affect the pliability of the hull and gives total control like a boogie board. Pisses the purists off too !
Not sure how I will attach the mat part this time, I might put in a raised beam or two rather than making material I-beams.
I put a GoPro on the end of a length of plastic conduit, not hi tech but its light , cheap, easy to adjust.
Bob, the decks are glassed so they’re not foldable but what are you thinking ? Did you want me to make a foldable paipo or foldable Taurus ?
Brett,
I wasn’t planning to but may get a chance to look for some waves in Canada and have been thinking about board options as I will be going to a few non-surf places first. No need to give this any more thought. The idea of a semi-rigid mat is an interesting one.
The Malaroo paipo is still percolating - trying to read some of Malaroo’s files into BoardCAD.
Bob
One of my mat ideas was to put sleeves on the top of the pontoons and slide batons into the sleeves like stiffeners on a sail.
Heres the nose rocker, Ive stuck with a flatter curve so the lift and planing is gentler, I didn’t want to create a ‘bounce’ with the inflated section behind.
Thanks for the pic for the gopro setup,I know it’s not rocket science but it helps to have a visual reference to start from…
The only thing you can do to make a purist happy is to be like them ,and where’s the fun in that?
you have a great advantage in that you can build your mat to suit your needs
You could also use the baton strip idea that you mentioned across the front to bolt this mat to the board…
and if you undercut the foam you could make the transition from foam to mat a little tighter…
(playing with the snip and scribble tool)
You’ve probably already thought of something similar, but I thought it was worth suggesting…
Thats how i saw it too Dave, but with the baton against the foam.
