I’m surfing a lot more now that I live in Ventura and am contemplating a multi fin flexspoon. This started out with a desire for a removable fin system for my single fin. I’m working with Robert at Robert’s Surfboards and he thinks a tri-fin setup would be good using the Probox system for outer fins. For center fin I like the Greenough system utilizing a “spine” with a slot and a “tab” on the fin that fits the slot.
Looking for ideas and predictions. This will be on a new flexspoon, 5’ X 20 1/2 and fairly stiff(for a flexspoon). Bottom will be approximately 1/8" thick and I’m not afraid to build it up for boxes.
I’m open to anything on this one. Will get some pics of board under construction.
Just a thought…If you go the usual route, the bottom will twist into a variable “V” in a turn. That will cause the rail fins to change their cant (increase) with relation to the center fin. A good thing? Not sure but something to think about when you set it up initially.
If the cluster is going to be a standard “thruster” set up, the back fin will need to be near the tailblock and therefore stiffen up a real critial area of flex.
Most of the multi finned flexies I seen have been twisty fish or quads. Maybe go down the Chipper path and put in enough boxes to experiment a bit.
a thruster seems counter-intuitive to me for the way you like to ride your boards (from what ive seen/talked to you about?); they dont generate their own speed like a big single…I don’t really see how you’d generate that motion on a kneeboard w/out feeling like a drydocked fish…?
ive been thinking about grinding off the fin on my kneeboard and putting keels on it, and building one of the spines like your edgeboard has…then i could play with 2+1 setups, keels, and singles. the other thing i wanna try on mine are rail fins. im looking for more release off the top w/mine in smaller waves. I had it out in some size during that big swell in dec…i like mine for smaller waves though, the size of the day we surfed at rincon was perfect for it…
whats the reason for leaning towards a thruster setup?
3 fins? As in a thruster setup, i think it would basically defeat the whole basic premise of the flexspoon. snap instead of flow, and of course no sideslipping.
a widowmaker setup, maybe. maybe small fins placed far to the rails with a significant amount of cant?
George’s bottom turn at honolua bay is just forever etched into my mind, so for me it makes it hard to understand flaexspoons with multiple fins.
