Ride report update!

Well today I was looking at the board and it had a hard edge on the back 3rd of the rail and a faint hard edge as far as two 3rds up, so I got the sandpaper out and sanded all off. :?

Result hold and drive is back! totally changed the board :D

I was doing hard bottom turns and S turn cut backs with ease today, so the hard edge is only across the tail now. Interestingly 360's now spin round a little slower.

Now totally stocked with how this board surfs, 8-)

Put a cork deck pad on too.

Yes, a hard edge promotes water release. Softening the rail edge, encourages water to rap around and "grip" the rail. This was the lesson learned from the 70s down-rail mini-guns. The early down-railers were fast, but prone to spin-out. The introduction of rail fins was an attempt to counter the spin-out while keeping the speed. I would think a soft edge or no edge rail would be important on a finless board. The softer-but-stickier rail you now have may explain the slower 360s. Water just doesn't break away from the rail as quickly.

Hey Keith, The board looks amazing. Hope you have been enjoying the recent swell. Looks like we might get a bit more winter next week! Fingers crossed. See you soon.

Got a few waves on the board today with my buddy on his bodyplane, these are the more flat weak local waves I designed this board for and the extra wide wide point forward is working out good for getting forward on the board to promote speed on flat sections.

Keith,

Is this the place we surfed on that small onshore day? There is some interesting footage of smaller handplanes in Hawaii getting some impressive lift.

I like photos of p-boards on clean, little waves. The scale is just right.

I really wish I'd walked back down that track and taken some waves photos. As tough as the sand walk was it would have been way more fun than doing circles are cardiff with a dying GPS.

It's funny how those two waves look so different - the top a bit crumbly but the bottom one does look like S. Those inside boulders were a killer.

Got some shots of me on this board at a local reef break last week, was trying to do some stand up surfer style off the tops, surprised from the photos how in the lip i got as finless and print this 180 turn is hard. still enjoying and using this board regularly. The green foam, 6oz, 4/6oz top had held up very well.

You have a good photog. Seems to know what would make a good surfing action shot. Board seems to be working pretty well, too.
