I know that been to Vargar enough times in the twin with points of no return and the works.
If your daft enough to do that sort of crossing in a single in atlantic or north sea waters the least of your worries is having a chute or not and surviving the landing. If you get out afterwards its going to give you an extra 6 mins of life unless you have a survival suit on and a life raft.
If you are even attempting such trips for ****s and giggles and not a pre planned ferry your PIC skills are severely compromised that having a chute aint going to reduce the risk factor. In fact why don't you ask a ferry pilot for a north atlantic crossing if they would prefer an extra 55ltrs on board or a chute. Lets face it if they did want one and thought it would do any good they be wearing one anyway. And from what I have seen of them departing west they hammer as much fuel as possible inside and give the middle finger to the MTOW.
