Odd Underwater course behaviour

[danurve]

So I'm evading a pair of escorts in BE67 after attacking a nice convoy. Sank 2-T-3 Tankers, a Troopship, a Celt Tanker & a C-3 cargo. Missed an escort at 850m stern shot, fast speed 2m. You know how they can step into overdrive and avoid your shot - cool. :roll:
Managed to get away and return to course. Or as I thought.
Everytime the boat contacts a way-point it goes into a hard to port turn and spun around in a circle. Yeah kind of weird I thought. Tried erasing the cojurse and rolling with another one, same deal.
Well enough of that noise, surfaced at a good time and returned to course, problem went away.
Bernard incident?

Bernard incident?
You can count on it. Someone probably had him manning the rudder.

This is common to overshooting the way point

it happens when a plotted evasive course has the
waypoints too close together the boat cant get its nose
around fast enough at submerged speed to make the waypoint
and starts looping it trying to get its nose off of it.
the solution is delete the waypoint or avoid closely spacing them.

subs turning radius increases with reduced speed and rudder movements.

Another explanation: Waypoint is on the surface. If you are deep enough, game thinks you missed it.

[Jmack]

waypoints to close to make the turn ...

Brag is right waypoint is on the surface and counts as "reached" when you're closer than 100 meters (ballpark figure). If you're deeper than that you'll never "reach" it hence the circling. :D

Ahh ok well the too deep thing makes some sence. Most of the way-ponts were at least a 1/4 grid apart. More jazz to remember.:know:
