Seen a new one that’s suppose to be launching next month
Back when I was "stealthy" 😂Submarines are "bulbous" at the front, meaning they have a rounded, almost bulb-like nose, because this design minimizes turbulence and noise when moving through water, allowing them to operate more quietly and efficiently underwater, which is crucial for stealth and navigation; a pointed bow would create more drag and disturbance, making the submarine easier to detect.
Yes, on the parachute effect. That comes from the forward velocity becoming too slow compared to the spin rate. Once that ratio is off, the arrow will parachute.I have been looking to try something different in a 4 fletch, recently it seems my 4 fletch blazer x2 is outperforming my 3 fletch. So these look promising for control, I was chasing less drag but have found as many others it is just so minimal it isn't worth the lack of stability in a tiny vane.
I think the drag/parachute factor comes from Olympic recurve with their light arrows and slow speeds at long distance, arrows shot from a compound it is just not an issue!
I was playing with vanes and Zingers a few years ago, 4 different vanes and 2 different zingers, 3 and four fletch on all of them and they grouped together at 60 yards. The heaviest 4 fletch set seemed to group consistently at the bottom of the group but no more than a couple inches, I shot them thousands of time for an entire season.
