Volume is a very loaded question. You are using EPS foam which is very floaty. The board is around 44 inches and 21-1/2 inches . You are about 5'10" and weigh around 160 lbs. You could easily stretch the board out another 4 inches to 48 inches, or 4 ft even, and still be comfortable kick paddling. : the paipo has to be 44 maximum to be able to take it on the sccoter bike between my feet,

wide and a very wide tail: when passing the plane of the computer to the real, I realized this, I thought it too wide, this is the result of a body, which tail measurement would be more appropriate?

You could also narrow the board to 21 inches as you seem to be a relatively non-wide person. this seems like a great idea

There is also the option of having a dome-top board (thick center going thin to rails) or an evenly thick board. :

I have made a few surfboards with this shape and I am happy, they work very well, and to make it easy, you do not have to make a bottom with a rounded channel, complicated to do by hand symmetrically. In this design, the central part is flat and the edges fall in this way.  very used for aircraft wings in slow bulges and difficult landing
I attach a quick drawing of the singing form

I have posted in a previous post the hydrodynamic studies in surfboards that have been done, it is not my own idea

How much float do you want, very buoyant, barely buoyant or somewhere in-between?
I need to love myself fast, there is overcrowding in the water without any respect for priorities. in a wave we can row 15 people at once ................ crazy. with this I think it will have to be high volume

fins, I like the keel with us box, this allows me to vary the response of the board in the water, later, more turn. backward, more grip, this gives me a lot of maneuver in the changes of tides so strong that we suffer, days of 4m difference high tide with low tide, the cantabrian sea is very hard in this

I want to apologize for so many questions, really you are all good people

No apologies needed! Maybe I need to apologize in forgetting your 44" maximum length ;)

Width... you will hear many different opinions on this, from very narrow to very wide. Many of our opinions are driven by our riding styles, the types of waves we ride, our own bodies, wearing wetsuits or not, and many other reasons.

Some thickness will probably make some sense given your crowd conditions. Where do you do most of your surfing?

On fins, I hear you about liking the flexibility to adjust fin position depending upon wave conditions. I do that with my center fin as well. My sidebites run in a narrow range of 1-3/4 to 2-1/4 inch, in a fixed small fin box (mostly FCS, a couple of Futures), although with some single plug FCS fins I can make a slight adjustment.

Big tide differences! I've experienced that in N. Oregon and Costa Rica, and the one time I was in Aquitaine France.

Where do you do most of your surfing? in san sebastian, zurriola beach. beach breaker
Aquitaine is 40 minutes away by car I sometimes go but not much, lack of time

I like the 2 + 1 system, but to test the parallel central finals system, let us use 2 + 1. It gives me much better result. that's why I want to transfer it to the paipo.
what works in a surfboard may not work in a paipo, but to calm my head I have to prove it

I'm studying Larry's great work incredibly well detailed. the downside that I have is that his designs are around 48 51, too big, when passing his vectors to the measure of 44 loses all the magic, gives a result of paipo patata

http://mypaipoboards.org/interviews/Lar ... humb.shtml

I am realizing that I have to follow the bodyboard designs and retouch it and give an aesthetic paipo, as I started at the beginning of this idea

weight of my paipo, I've been looking at bodyboard materials ranging from 1.3 to 1.9 pcf, in some the 2. are mixed. My eps is 25 kg / m3 = 1.5 lb / ft3 with the fiber will be well off compared to these, so that if I follow the sizes they recommend, I would not be very wrong, or so I think

what gives me a question, you like the volume and float that gives the brand http://sciencebodyboards.net/board-finder/?

I'm a fan of twin fins on bellyboards. I've ridden a single fin and 5 fin bonzer, but really prefer finless or small fins (under 4"). Positioning a pair of twin fins close together, like you propose, is an experiment. It may or may not work. I'd suggest riding prone would be very different to stand-up with such a design. If they don't work, and you could just add a set of FCS plugs with more standard positioning.

I've surfed Zarautz - does it get very hollow? If not, a board that planes well would be useful. There are also some gems west of Zarautz.

I've seen some racks that go alongside the scooter, that would allow a somewhat longer board.

I like a volume around 20 litres - as Rod said, this is a personal thing.

I wouldn't worry about trying to get it perfect. It's going to be an experiment and you'll be down the bottom of the pecking order, in the water.

Huh...lot of food for thought but after a fast pass this morning on my way to who knows what the thought I had was twin fins for paipos...larger fins the closer to the centerline, smaller near the rails...to allow for wider tail width of paipos. Seems like there should be some kind of mathematical formula there...either existing or waiting to be created. Probably with variables for distance from actual tail edge.

Off top of my head...pointy though it may be, maybe what would be needed in terms of fin size, esp depth, is that you have about same amount in the water as board leans over on a rail. So roughly, maybe a line (perpendicular to stringer) that runs straight from bottom of rail, touches deepest part of further apart fins, and also touches deepest part of more central fins. Eyeball, seat of the pants thing. At least as start point for experiments.

bgreen: I spoke with the police a year ago, I showed them the supports for motorcycles and the stores where they sell them, they answered me, that in certain countries the European assistance is allowed, France for example, in the Basque country Spain is illegal and they can fine

size of the paipo. I am an animal, a very hard head

all the time I have thought to bring the paipo vertically red square of the photo. this limits me the height 44, if it is very high, I do not see, I can not drive. but if I take it orizontal green square photo can be longer, leave maneuver to make a 52. this gives me a lot of joy, I will not make it bigger by hair with the wind and cars

PS: I improved the representation of the photo, this is more clear as the paipo has to go, dangerous, but I have no other option

I studied this to make my surfboards, it's a quick, not scientific, I'm not an engineer but the result in surfing has been good

size fins regarding its separation from the center. if we take for good a central single keel of 8 in another side table in traditional position, close to the rail are 4

of hangs the separation in which are the 2 lateral fins, varies, to a position of 100mm of the rail gives a hole of 6.5 inches, you have to ask for this size of keel to put the paipo, I had studied it from a better way calculating the areas of the fins, but for a quick explanation, I think it's very visual

I had similar on small motorcycle (Honda 90 in 1970), horizontal board mount. Couple "U" shaped brackets attached by bolt on to the frame. The main issue was cross winds! On the hwy out of town (Santa Cruz) getting passed by big trucks was a bit like a suicide attempt. Also, along the coast there, afternoons most days got pretty stiff onshore wind. But it did get me around for awhile. Much prefer though being able to get into a warm car with heater after surfing.

70 to 75 percent of the 22" board width, or somewhere in the 15.4"-16.5" range = ok

(measured at 3", 6" and 12" back) were 12"-16"-20" ? I can not find out how you got these maths, can you help me?

LarryGoddard: The outline shape of the hotdog boards is elliptical, and for the high-speed boards, I use an 'Exponential Curve" which gets straighter towards the rear half of the board.

06 BDS (top drawing on page). By 1967, I had settled on the 54" x 22" overall board size for my favorite point breaks, Malibu and Rincon. On this page, with the top drawing, I explored the possible nose and tail widths for my next board. I chose the extra-wide 19" tail (measured here at 2" up from tail end, because of the small-radius square tail chosen for high speed). I wanted a nose width of around 70 to 75 percent of the 22" board width, or somewhere in the 15.4"-16.5" range. I chose to use the 16" nose (measured at 6" back), and the resulting nose widths (measured at 3", 6" and 12" back) were 12"-16"-20", (that nose line is drawn slightly darker).

Speaking of Larry Goddard's designs, a number of my boards have been based on his designs:

viewtopic.php?f=4&t=746

viewtopic.php?f=4&t=746&start=10#p7081

viewtopic.php?f=4&t=797

From the original board, my boards are thinner (and foam distribution has shifted forward), have smaller fins and bottoms are no longer flat, with a foil more similar to a stand-up board. Wings are another addition. There have been other experiments - scoop deck, deck handle.

I'm very happy with my latest board. It is worth recalling that Larry made his boards to go fast and do sweeping turns, at his favourite wave Makaha. They weren't made for tubes .

Oops, just realized your pics above show the board surface perpendicular to direction of travel on the bike. Mine was side mounted so that it rode along one side of bike somewhat same position as walking with it under your arm only lower down. I had one like that on the right on the motorbike and on the left on bicycle. Both worked ok but with the wind issues for sure

I have read the work you have done and it has served as an incentive for me to do mine, a great job and good explanations. Congratulations

Too bad because so much more aerodynamic that way, less drag, less turbulence. How about 1 wheeled or 2 wheeled light trailer? Axel and wheel size of course could be less "heavy duty" depending on roads and distance you would be traveling.

work today. the 2
paipo, large, 52x19x2.1 concave with flat center, from nose to tail. Chamfer on the sides
paipo small 46x21x2.2 nose bee to concave w in the middle at the end

I have cut a piece of eps in the form of a maipo to 42 and it is really bulky, to that extent it is more interesting to make a bodyboard in eps fiberglass

I can not put anything on the motorcycle, or supports of any kind, the beach I have far away to go by bike and tired bolber home, but I think that with these measures and driving slowly I can fix them

Asier,

Do you know anyone you could store your board for you at the beach. I've had contact with some Basque surfers who might be able to assist?

the beach of the zurriola there are places to leave tables with shower ,,, this very well but cost 320e a year, a lot of money for the few days that I can go to the beach.

I'm going to try the paipos and the motorbike, I hope I can go to the beach safely. thank you very much
