i have routinely used the kiel canal, with GWX1.03 i have noticed several spots where the time compression is up to 128 without adjusting any values in SH3 commander. Just be sure and use the option to plot the "search pattern" that leads you out of the canal or into it either way your are going.
dont think so much about the real life time used, think of the fuel conserved. by not going around the horn you have extended your lethal action range further out into the western approaches.
good hunting!
