"Smaller the board the faster it must go"

Found this paper on www.mickeymunoz.com as I surfed the internet searching for a review of Mickey’s 12foot Surftech, NZ$1480-1500, exchange rate probably NZ$1.00-US$0.66-68, anyone able to critically review the board?

Back to the paper, just to add fuel to the embers of Roy’s board speed thread, possibly the biggest thread in this sites history.

Well worth a read and a critique. http://mickeymunoz.com/scrapbook/surf-physics.pdf

MrT

can anybody break down the pdf into bite sized chunks and post them?

MrT, There are a few guys at Cardiff Reef in Cal. who have 12ft. Surftech Munoz boards. They fall into two catagories: Older guys who need an easy wave-catching board that can actually turn pretty well. And stand up paddle surfers. Stand up paddle surfing has become more and more popular on small, mushy days.

Mostly I hear that they really like the boards. General comments, nothing scientific. Doug

Howzit MrT, wouldn't it be easier to just print the info, it's only 6 pages. Aloha,Kokua

I am in thr first category, I have a 10-6 X 25in but had the back made too narrow, therefore not catching waves easily, the 12 ft board looks like the one, just to get more wave time from further out. I like the philosophy of catghing four and going home, the Munoz board might make that an easily achieved goal.

Hi Kokua,

There are file size limitations for uploads, the pdf file is two large, I have copied and pasted on to word, each page as a separate file, however that is still too large, I am looking for a tip on how to compress it even furher. The reason for going to this hassle is that I have had a pm from someone who cant access the link, asking me to email the article to them, I only have access to hotmail so attempting to put the file up on the BB.

MrT,

I think your title is taking the quote from the paper out of context. When I saw your title I thought you were implying that a smaller board will go faster than a longer board. The paper says:[=1]

Quote:

[=Black][ 2]The smaller the board,however,the faster it must move if the board and the surfer are to plane rather than sink.[/][/]

The paper isn’t mentioning anything about the maximum speed of a board. Only that a board with less planing area must travel faster to support a certain amount of weight in order to plane, and therefore not sink.

Kind Regards,

Hi Matt,

Mechanism of Surfboard. Large oceangoing vessels

displace a great deal of water, which moves around the

hull as the ship plows through the sea. But a highspeed,

suitably designed boat can “plane,” rising up

out of the water and gliding over the surface. Just so in

the designs of surfboards. Early boards were quite

long (10 ft or more) and usually made of plywood.

Because of their large area, they experienced relatively

large frictional forces as they moved over the water.

Many of today’s boards are shorter and very light,

made of foam and covered with epoxy. The smaller

the board, however, the faster it must move if the

board and the surfer are to plane rather than sink.

“I agree, in retrospect, there is insufficient info to draw the conclusion that small boards move faster overall than large boards, point taken.”
