Not at all the same board. Template is only one part of board design. But even the templates are different, boss up has a small hip just up from the leading fins. Bottom contours are obviously very different. But more important is the rocker. The mid 6 has way more entry rocker and isn’t really meant for small and weak waves. Boss up images a fairly flat entry rocker and can grovel. That said Boss up can also handle steep waves owing to the narrow template. Just got to get in early.
I have a 7'0 G&S thruster for those small gutless days that even works in head high steep barreling days I got it for post back surgery to get me back out into surfing and have continued to break it out on those smaller days the major problem it's next to impossible to duck dive guess I need to break down and visit the shop Be well my friend Thanks for sharing as always and God Bless 👍
