This isn't a big deal, but I get sick of having to maneuver my boat extra slowly so I don't destroy it and when I get out it consistently goes skipping away, which is all very realistic except for the exploding against the shore part.
By no means should they be invincible due to the fact that you would be unable to destroy them and carry them with you, but I definitely agree that they should have increased health. Every time I try to make some sort of track or river for my boat to follow, it always seems to blow into millions of pieces due to declines or turns.
