“The Midrash explains that when one bores a hole under his seat. he effects everyone in the boat.
Totally agree, even if everyone in the boat is wearing a PFD. However, there are exceptions when bowling (boating??) in Kiamesha Lake (the topic of this thread) since boring 3 holes in the ball is generally a prerequisite to success in rolling the ball down the lane (Lake??) and knocking over the pins. I understand the mashal to a boat but not sure how it applies to the matter at hand.
