I don't get it. I feel like the more I read this site, the more confused I get. Wouldn't a diamond tail change the length of the rail compared to a square tail? Wouldn't length of rail effect riding characteristics?
Send me your dinged, damaged, and yellowed.
Not sure if this answer is going to help since the thread has been moved. Let's back up a bit on tail design to better understand where the diamond fits in. Any tail that has some resemblance of a corner is going to release water there instead of along the curve of a pin. On a generic short pin, the rail will normally continue to taper around the curve to the stringer. In any tail with a corner, the rail will only taper to that point. So, the "effective" rail length of the board is really from the nose to that corner. It is confusing if an overall length is established then the diamond shape is laid in from there since the effective rail length is now shortened. The 1-1/2 - 2" projection of the diamond tip is not going to have much effect on floatation or volume, so designwise I would call the effective length of the board nose to tail corner and let the actual overall length be plus the projection of the tip. Or simply handle it as if it were a plain square tail and add the diamond tip to the length.
On the original #1 post of this thread, if the guy would have just ordered his cut as a square tail then put the diamond in himself that bunged up corner would have been cut away.
What’s funny about all this is I have (read carefully) NEVER said that I was an EXPERT in Surfboard Design. I have stated many times tho what I like and what I don’t like. In reference to the old style Pigs and the way they rode, I merely stated my first hand experience at having ridden them many years ago. I never want to go back to riding those dogs er pigs. I leave design theory to dinosaurs and monkeys. Good luck with the monarchy. Long may you reign. Oh and liking someone and respecting them is not the same as ass Kissing. Lowel. Shaper since it was too late.
I'm certain the trifins built in 1960, were just as refined as the one built in 1990+. What I was trying to convey is that surfboard design has evolved its design, getting stuck in the past is like driving a vintage car for your daily driver. "gee why is everybody driving on the freeway so fast?" "gee why can't I take turns like that car". remember when your car used to get flats on a weekly basis?.... When was the last time you got a flat?.... You just experienced progress!! But once again I digress.
Every time an old surfboard shape comes back around they get more and more refined. To think that old down rail straight 3 finned board is the same as a current board would be like comparing a 1968 Dodge hemi Charger to a new 2018 Dodge demon charger..... Yet it has 4 wheels, and it burns gas too. But that's about the only similarities. and again I digress.
I have yet to see a true 1960's style long board in a current surf shop. Every one I have seen has more modern rails and rocker.... Even the D fin ones.
Absolutely! You and I have had fun jousting on Sways over the years and unlike others there has never been any personal friction. As I stated well balanced and realistic comments. I didn’t invent anything in 1964. But, was sure having fun in my “ignorance”.
To be clear; you are an IDIOT. Haha!
Wait. What? What just happened here?
