Re: Am I asking for too much?

I ride 4GF and G-Mat surf mats in conditions from tiny to OH+. There are fatter mats available for small conditions but I find that technique on an all around mat can do the job in small junky conditions.. Less air (I mean barely any) makes catching waves easier (reverse rocker suction effect) and t...

Re: Plywood and cork

Re: Plywood and cork

I have been in slow-mo on a cork core project with each step weeks and even months apart. I will give a full report when I actually finish sometime in this decade. I was initially going to use titebond III to adhere cork to paulownia ply but the titebond manufacturer I called raised concerns. I turn...

Re: Top vs Bottom Layers of Composite

Asier, I like that you achieved the right amount of flex while retaining sufficient strength with your layers. Looks like your board would travel well. My board will travel to Costa Rica and Hawaii. I assume your examples use epoxy? Your experience is helpful. Some say that if you vacuum epoxy into ...

Top vs Bottom Layers of Composite

I am finally getting around to making a Paipo. I found this link while thinking about what layers to put on the top vs the bottom of the board. 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 s...

Re: Bodypo New Blank

How did this work out for you? I looked at californiasurfcraft.com/products/bodypo. I like the idea of something that duck dives easily, has more float than wood and at the same time has flex that might give some mat like feel. Can it do a big bottom turn with acceleration when needed?

Re: Fin Advice

Is that for Jacksonville or Costa Rica?

For plywood paipo, also consider wakeboard fins. Some are like small surfboard fins and attach via metal bolt the could be counter sunk on the top.

Re: Finned Xylem Paipo

Thanks for the great comments. I will definitely reset the toe in on the Xylem sides to parallel. I did try some asymetrical-foiled sides one day without benefit but the varied conditions make it hard to conclude. It will also be interesting to go back to finless or just minimal fin using just a nub...

Re: Finned Xylem Paipo

Correct that riding flat nose rocker constrains big bottom turns on toothy waves requiring earlier turns,, angled take offs, or riding back further. However, I only ride way back in situations where I am committed and all the nose rocker in the world would not help.. That's rare. I make a point of s...

Re: Finned Xylem Paipo

Right, I neglected to mention the test with Vektors as sides. They have more height and less base than the nubsters but felt drag. I would have to reset the toe-in to straight to conclude on nubsters or Vektors. Funny, Rod perceived me as having more speed on the Xylem and my perception was that I h...

Re: Finned Xylem Paipo

The board is 48" long. It does have 3/8" "taper" in the tip of the nose starting 3" back. Maybe I should call that rocker? That transitions into the side to side roll a couple inches back as well. The trick in not pearling is to get on to the side rails at the right moment. However there does seem t...

Finned Xylem Paipo

I have been riding finless piapo and surf mats for a few years now. In most conditions I can control either to go where I want to go. However, in some conditions I felt like some combination of my skill level and finless craft design was a constraint .. I am thinking of very late takeoffs in heavy o...

Re: Double-dipping...

You have to say what's true .. Our age, apitude, and experience have to be considered when designing or selecting a ride du jur. I am 61 with the usual set of issues and spend more time in an office than in the surf. I love the feel of finless surf mats and wood paipo but each present challenges as ...
