That is great to hear. I never went that direction w/ prone craft due to my skepticism. My loss.

Re: TP Displacement Hull Board

I however prefer most of the board to be a planing hull as i don't like the way a full planning hull cuts through and then jump out of the water (watch greenough riding a spoon) I've never ridden a full displacement hull prone but I suspect the feeling and maybe even the actual effect, does not tra...

Re: versions of gus acosta?

That's a LOT of fin seems to me. With the vacuum rails and that much concave, I would bet it would fly with no fins at all as well as hold in just tine.

Re: Plywood and cork

I have never worked with cork but might be you could seal it and prevent a lot water weight from saturation. Squeegee on so super thin, multiple coats of....something, epoxy perhaps. That might act like the spackle cheater undercoat used when glassing EPS foam to prevent the resin from running all t...

Re: versions of gus acosta?

Video seemed like even without fins the board powered around soup pretty well, held an edge. I know with concaves there's a lot of variation in effect from small variations in the shape of the concave, esp the transitions to flat on either side. And of course all that interacts w/ rails and the tran...

If only interested in tail shape that is totally fine. But I do think a great deal, if not most, of his design in in the bottom contours

Re: Plywood and cork

I think having the plywood on the outsides of the sandwich, you may still have pretty darn hard edges if/when they impact your body. I do like the idea of experimenting with sandwich construction using easy to source materials!

Re: A couple of waves in Galicia, Spain

"long/narrow/flat" = Alaia! This video (one of my most favorite surf vids) is standup but really a master class in how that sort of board works, what kind of lines it likes to draw. Some variations will undoubtedly show up for prone riding but still.... https://www.youtube.com/watch?v=UvYqok4jrW0 Ro...

Re: paipo 50 inch drop knee?

Channels have some of that effect, depending a lot on how they are shaped i.e. rounded transition to the flat part of bottom of board holds, sharp edge transition releases and I don't know but may hold less than plain flat. Even on 6 foot alaia with significant channel running down the center of the...

Re: Bodyboards discuss (the soft paipo)

Beautiful camera work to me. Must admit I"m not a fan of the GoPro POV stuff, esp in tiny surf where you can't really seem much of anything. This though, made me happy just watching Interesting wave I think at 4:24 where only contact points w/ board are hands and a very small area of his inside hip....

People sometimes surf standup on regular bodyboards so I would imagine you could also kneeboard!

Re: paipo 50 inch drop knee?

I have always wondered how a paipo would work as a drop knee board. Since I am not a drop kneeer myself (I tried several times on a bodyboard but I have failed so far), I would be curious to know the result of your tests. I guess the board fins will help. With out fins my good bodyboarding friend c...

Re: Bodyboards discuss (the soft paipo)

If iFoam is same or similar to what I bought about 25 years ago, shaped in keels and concave paipo, it has tremendous float and really is bomb proof. Shape it and ride it, no sealing or coating of any sort needed. The outfit I bought the board from has long since vanished by the called it "automobil...

"... I'm still on a quest to have a custom bodyboard made as similar to my paipo design as possible to see how similarly they ride give the different constructions." Now THAT would be interesting! Use a mailing tube to send them a construction paper template, and define the angle of the rails. They...

Re: Top vs Bottom Layers of Composite

http://www.bertram31.com/proj/tips/core.htm According to that article tension strength is set mostly on the bottom skin. The top needs proportionally less skin to get the overall tension strength to prevent buckle and break. However, we also need enough load strength on top to prevent dents and din...
