Long-time-lurker, first-time-poster here. I am stoked to be shaping my first board and wanted to run my plan by those with more experience to see if any of my dimensions look way off. I don’t expect my first board to be the best, but I’m trying not to make a door.
The goal is to emulate a Kane Garden “Classic Twin Keel” fish that my buddy had over 10 years ago. It was the most fun board I have ever ridden to this date. It was fast, loose, and easy to paddle. If memory serves correctly, it was a 5’6”, although it is possible it was 5’8”. My aim is to replicate that fast and loose ride and easy paddling. At the time I was 6’3”, 195lbs and had been in water polo year-round for 6 years. Now I am 6’4”, 225lbs and my paddling stamina could use a little work.
In doing my homework on the KG board I found the following information:
- 5’10” / 16.5” Nose / 21.25” Width / 16.75” Tail / 2.55” Thickness
- 5” swallow tail and 8.5” wide at tail block
- Single concave entry into split double with vee of the tail
In looking at a picture of the bottom view of a 5’10”, with a grid view overlayed, it looked like the widepoint was about 29” in from the nose, or 6” in front of dead center.
In drawing the full outline at 5’10” I was thinking that the board looked a little small so I scaled the board up, proportionately, to 6’ / 17” Nose / 22” Width (at 30” from nose) / 17.25” Tail / 8 1/8” tip-to-tip with 5 1/8” deep crack. I am doing the thickness at 3”.
I have not been able to get the rocker details for the KG but I have been foraging through the archives for the last two weeks and it looks like the generally accepted fish rocker is about 3.5”nose/1.5”tail for retro and more towards 4”nose/ 2”tail for modern/performance fish? I am thinking of splitting the difference at 3 ¾”nose/1 ¾”tail for this first board. I live in Ventura about half a mile from C-Street (point break) that can get a fair bit of onshore wind, so that’s where I go most often. Does this rail rocker sound way off or reasonable?
I want to experiment with fin placement/orientation and was looking at the adjustable fin systems but the limited adjustability doesn’t seem worth the price of admission. Reading a thread about removing glassed-on’s encouraged me to just go that route and edit as desired. This just means I get extra practice at glassing! Initially I’d like to try and setup the fins as similar as possible to the KG fish. I know they are double foiled, they have some toe and a slight cant….but that’s it. Since I want to play around with fin placements I was thinking of starting with trailing edge 2” up from crack (7 1/8” from tips”) and 1 1/4” from rail, I seem to read good things about 1/8” – ¼” toe and 4 degree cant being a fast and loose combo so I am considering this. If anyone has info or templaye on these fins, beyond being double foiled, that would be awesome.
I have tried to thrown in some pictures of the the KG fish I want to replicate. The green one is a 5'10" , no clue what size the black one is.
