Bit of a hijack maybe , but instead of starting another thread , this seems a good place to ask ....
I was looking at a Miller V Skate a while back and noticed that he'd tucked the rail edge all the way back to the tail - about 5 mm at the leading edge of the fins, not rounded off though , still a definite edge.
Surprised me a bit as I thought prevailing wisdom was to keep that hard outer edge ' a shaka width 'up from the fins.
As far as I remember every board I've owned or even looked at has been like that.Except maybe my 80's McCoy thruster , that had round rails at the fins , no edge. Certainly all 4 that I've shaped, ha.
I did a search here , but nothing specifically on tucked edges at the tail .
Miller knows what he's doing , so what are the benefits ?Spose what I really mean is what would the benefits be for me a late 40s weekender.
Just remembered Brian Bulkley does talk about it a bit here
I'll take the liberty of quoting him
''I'm a bit of a lone ranger on this idea. But many like Lost and the other big boys do tuck the edge a bit, where as the other I don't know world wide, but maybe 50% have the non tuck knife sharp straight down square in the tail. Not like I haven't done it, but I've looked at a board thinking nice shape, from another shaper, and gone out to ride it, and it didn't suit me to say the least. Still worked, but the whole time riding it, I was thinking how much better it would have worked with a slight tuck. This is one level. For the narrow boards of the Slater dynasty it made more sense to me to keep the chippy boards on top of the water. Rails were thinner and maybe boxy, and the freedom to punt airs was made. They definetly release for aerobatics. Big plus. Skipping flipping, rolling upside down clowning around, a benefit for sure. Doesn't mean a tucked under 1/8 to 3/16 won't do most all of this as well, just maybe a slight more controlled release. These are only opinions, of coarse, and there are many feelings in both directions. Now I don't normally take the edge off as much as tuck it more than most shapes I've seen. Now I'm not always around when the board is finished and they end up with more edge. Like I said, still go good. Just a little less skip on a big bottom turn and especially on less perfect conditions. I was on a trip with a group of friends with new boards and was checking out the new stuff. Most all had a nice edge tucked farely normal for my taste, and with some texture, saw this shredder kid slightly skipping of the bottom. pissed me right off. Got back to camp and made him give me his board. I proceded to assure him I wasn't out of my mind when I grabbed sand paper and ripped into his fine tuned edges. Next day he was ready to test it and let me know if I owed him a surfboard. Night and day, loved it. Smooth transitions into the lip, blasting everything in his path stoked. I've done this for years but don't go sanding your edges off and blaming me for ruinin your board. Lately thinking with the deeper concaves, I'd like to give it a push to the next level. Ruin it or well, make a deep butter concave. Forgiving but with acceleration of a deep concave. Push it to far and somethings got to give. If I lose performance, I'll back it right up. Lot more can be said for different combos in design. This is a touchy zone. Won't do it to a customer yet. I'm going to try to have demos of what works soon, but with my moving back from CR, could hold it up some. Maybe late July or soon there after. Thanks for the inquiry. photos in a few days of my new one. Just need to get in the water. Whats with the wind. Kinda hard to tell whats up in these conditions we've had a lot lately''
