High Density Foam Stringers v Wood

[ric_vidal]

I made a complete board out of PVC foam last year. It still has not been in the water. It is heavy but hard. Ill find some photos and post them. platty.

Platty, that the board you did with the Klegecell blocks?

ooh ooh!! the hot roc is famous!!!

Not the Hot Roc ya blockhead!

Beautiful board mate, love it!

P.S great site too!!!

how long/what size is the fin Platty? on how long a board??

[platty]

The board is 6'6" and the fin is 8.25" high and the base is 5.50".

The design is from a 70's Surfboard and Construction manual that was posted as a pdf on Swaylocks a while back. The board is based on the Tony Staples 6'6" rounded square tail. The outline and rocker are as the plans. The deck camber and rails are what looked and felt ok. The bottom rails are pretty close to the plan, but I put a slight edge from just infront of the fin through the tail. And a little bit of V through the same area.

Made from 200mm x 100mm x 25mm blocks. (8" x 4" x 1") These were glued end to end to make 21 7' x 4" x 1" planks. These were then cut to the desired rocker and glued together.

I think I might call it the "Tufheavy". It is glassed with a single layer of 4oz top and bottom and glossed using UV resin. It is pretty heavy for its size. This is by no means a breakthrough in blank production. It was a way of using a product that was only going to be thrown away. I can't give any comment on how it goes yet. Hope to get in the water soon. platty.

So I have just WON (love that term) a Sean Wilde 9'8" on ebay and it has this compressed foam stringer and of course last week I ring up a surf shop and I get this sales spiel that these are so much better than timber ones.

Can someone shed some light on them please?

Also what about Sean Wilde. I googled him and boy he's been and done a lot. Anyone out there riding one of his boards? What's the verdict?

You will have to give me a month or so to give you some feedback on mine.

peace.

I'm still riding one of his very early Robert august Performance shapes. It must be atleast 7-8 years old..... Before Sean coming into the seen I would only ride Gary Burdens shapes (The Family, Astro etc)
Sean's shapes are the goods .....

Maybe someone should read the basic fundamentals of planking and the fundamentals of plank lengths and adjacent plank % overlaps and scarphing in determining a hull's integrity. Herreschoff is a good beginner's book.

That pictured pictured might need a makeover to get maximum strength.

Otherwise it relies mainly on the glass and resin job.

Hey puurri. If that someone is me, I'll give you a quick insight into my background. I'm a Shipwright (boatbuilder) by trade, with over 25 years experience working mainly in the composite boatbuilding industry. I know what a scarph joint is, and have made many over the last 25 years.

These blocks of foam were 200mm by 100mm by 20mm. I not going to waste my time thinking about this to much, but if I were going to put an effective scarph in each block, I would not get anywhere. It was more of an exercise in shaping, and recycling some old materials. As the material was only going to be thrown out. platty.

No sweat mate,

I suppose that you did not qualify the terms of reference in the matter.
I supposed that the talk was/ is about best results for a planing hull; therefore up for discussion/ critique/ of optimum strength construction techniques for surf planing craft. I got in a bit early on the klegecell/ resins and composites bit in the early 80's and watched it closely until I got out of the game. Maybe this requires a new (specialist) thread??

My experience was more in timber construction. (not "wooden boats" as the Yanks call it)

Open for discussion in a propsed new thread "optimum hull shapes and construction techniques"???

Just wanted to finish off this very old thread with a little piccy of that 9'8" Sean Wilde sitting in a custom frame I had made for it in Bali, it's home for the past 7 years. It just loves the tropics and sliding down at Tugu beach.
