I ride a mountain bike very often, not as much as I would like, lack of time. I do not compete, but if I do my kilometers, I will have to learn to apply the strength of my legs to the fins.

I have surfed for many years and I have often met people in bodyboard. It is amazing how fast vertical super waves and unbearable pipes go down to my level of surfing. but they seemed to enjoy while we with the tables we could only look at them with astonished face. little by little I will go learning, I am not an excessively talented person but if I fit easily

I hope to finish the paipos this week maybe the first days of next week, I really want to try them.

I will tell you the adventures and I will post pictures, I want to thank you for this support.

To jam I'd add - confiture de cerises noire. I wish I'd bought more.

My first surf on a paipo was a dispiriting experience. With no previous experience with swim fins/flippers my legs tired quickly, I caught few waves and they closed out. It took me a few surfs before I started to get the right waves and reconfigure my thinking. I had no background in prone surfing so it was all very new. To add to the situation my friends didn't get at all why I was riding a prone board, even after my back improved.

nomastomas wrote: YES! I would only add that kicking helps to propel us but, just as importantly, it lifts the lower body into a better planing position. Also, the prone rider is "caught" by the wave, and paddles only to reach a position where being caught by the wave is inevitable. This position is where the wave is cresting or soon to be cresting. To successfully compete for waves, you must sit deeper than anyone else, and learn to turn-and-go no matter how steep the wave. The late take-off is our bread-and-butter, embrace it!
Amen on that, Nomas. I do need to use a thicker, full-railed board on many of the East Coast waves for catchability at least until the size kicks up. Today and yesterday, in Cape Hatteras, I often used the tail dip method of getting into our little curls--when from a sitting position you sink the tail of the board into the water and then use the buoyant trust to enter the wave. This would be less feasible on the thinner boards I ride in reefy/tropical/longer period waves. But in almost all cases the late-takeoff is the name of the game.

I have never tried a tick, buoyant paipo, but I guess the take off technic I described earlier (to swim pushing the board in front of you) wouldn't work in this case. I tried sometimes this technic on a bodyboard, it didn't work well. It is interresting to see the differences between tick and buoyant boards like bodyboards and thin boards with neutral buoyancy. The take of is different, but also the ride, for instance the "superman" stance doesn't work on a bodyboard.

Too true. If by "superman stance" you mean arms outstretched in front...I must confess this is something I really enjoy. Throughout my life I have had occasional surfing dreams where it's a mix of surfing and flying and even in my most hardcore standup days the dreams were really more like Superman flying or I suppose in more modern terms the view was like a GoPro forward mounted on the nose of a board.

This poem started with the idea of a paipo 44. It is curious how the design has been developed thanks to your help. without you to make those paipos would be impossible you have helped me a lot, thank you very much
Made with fiber and epoxy eps
Blue 46.5 inches for flabby waves.
The 51-inch garnet is a cut for waves with strength.
Keels made of 3mm aluminum inspired by aircraft stabilizers
The paint finish leaves a little to be desired. I have to improve. Make me with a computer, compressor, paint gun ... very expensive for my economy.

Very nice boards, I like the blue one :)
But I keep thinking that you should replace these aluminium fins by regular fins, much less dangerous.
Maybe even try with no fins at all, just to see how it works ?

I much prefer a bicep leash with the plug about 8- 10" down from the nose.

A shot from the tail down to the nose will show off the rocker better. They look like lethal weapons. Looking forward to hearing how they go.

I once went over the falls on about a 5 foot wave and landed on my back on my fin. Fortunately it as a moderately thick, home made fiberglass fin with a blunt foiled edge. Still, it cut through a 1/2 inch neoprene wetsuit and made a nice gash in my back. I was very glad that the impact was between spine and outer edge of my back and not on my spine. Coulda been turned into a quad in an instant!

The rounded edge looks safer, but in case of a brutal collision with a human body the aluminum won't break or bend.
Why aluminum by the way ?

If fiberglass or plastic breaks it generally leaves incredibly sharp and jagged edge(s)

I work in a factory with laser cutting machines, I am used to working with these materials, aluminum, steel, bronze ... on the other hand, and in my place I have adequate tools to work with aluminum. I do not have a welding machine, it hurts

next to my house there is a warehouse and sale of aluminum, they sell me aluminum plates and profiles that want to 4euros a kilo

The raw material for experiments is very very cheap. the density, weight of aluminum is the same as the material g10 fr4, so I have the same weight in the fins, but this is a lot more expensive and polluting

carbon and fiberglass when they start explode, like ceramics, blades like blades. It is not very common for it to pass in one fins but the aluminum will bend without causing cuts.

working time. Now that I know how to do them, I take very little time to do the keels, in fact, as its base is removable 3 + 3 + 3mm, it goes to screw, I just have to make the thin part 3mm sheet. to make 2 keels snow just need 30 minutes of work.

to make them in another material g10 for example I have to buy a sheet of 10mm, I do not see the system of 3 + 3 + 3mm in this material, and spend ohas wearing, too much work to get a result that I do not know if it would be suitable. keel shape, aera ....

Today I tried to get to my paipos Freddie Cruger on the bike, I am very happy, it has only been a short trip, but I have been able to carry the 2 with all the security, when I enter the water I'm only going to take one, but today It has been a test day. I have to make some covers, some sewing machine

I don't recall if you posted this info or if anyone asked...are you coating the aluminum with anything to protect against corrosion? The old aerospace industry worker in my has to ask since you've done all the work.

I have given them a thin layer of varnish with a spray bottle. however, aluminum creates a white surface layer, it is ugly, but this crust protects the aluminum from the inside.

I do not believe that they are the definitive fins. I think I'm going to do a few models as I see the needs, with how fast I do them, I'm not going to spend time finishing

The aluminum alloy magnesium 5083 when it has the desired shape and is the final use this alloy, is very good for the sea. I have many ideas in my head. Now I am more concerned about improving the appearance of my paipos, I do not like its finish. quengo that improve the way I work fabrics, resins, polished ....

5083 aluminum alloy magnesium in its formats of plates, tubes, plates, bars, sheets, is used in the construction of super ship structures, rail cars, containers with pressure at low temperatures, defense applications, high strength structural towers after of welds, mobile cranes, bodies, dump trucks, platforms, hulls of pleasure boats, mining trucks, missile components, etc.
