they should have just hooked a rope up to the ass end and pulled it off the rocks in the direction from whence it came. at the very least, they should've hooked a good rope up to it and taken it to shore with them so they wouldn't have to go back out to hook one up later. i am confused on why the boat recovery would be difficult. especially if they had a rope on it. in fact, that seems like it would have been the easier way to recover the boaters too. unless they were scared it would capsize once they started pulling it backwards.
