Are your play sessions very long? In new saves I can play hours at a time. But in my current game, which I've been playing for 9 months or so, I can play about 45 min and save once before I run into EC 12. It also has been crashing from time to time but I think that was CC related. A large part of my issues with my current game is the household size (24). Anyways, you might try cutting down how long you play at a time before saving, exiting to the desktop and relaunching, particularly if you've spend long sessions in CAS/Stylist/plan outfit/change appearance.
I'd be very concerned about seeing a sim with a boat (or an animal) as a parent. I have no idea how that happens. Portering to a new save seems a good way to go.

To me that's a sign there is probably something wrong with the world. Assuming you are using Overwatch, I'd change the setting to Auto-reset stuck sims to false. You'll get a notification about stuck sims but OW won't reset them. Right click on the thumbnail of the stuck in in the notification and the camera should zoom to that sim's location. From there I can sometimes figure out the issue. Sometimes it's a fence (those hedge fences are always problematic for me), sometimes its the location of some object that I can move, sometimes I have no idea and just reset the lot and hope for the best, sometimes it's NPC sims getting stuck behind Late Night NPC doors. Or it could be a problem with the world design you can't do anything about. Once I attempt to address the issue I usually have to reset the sim manually.
I don't really know how to avoid corruption. I know of a few things to never do in TS3: use TCE to delete a sim, ask a mini-sim to move in, accept the free vacation opportunity. I've never seen a list of 'best practices' to avoid corruption in the game. Actually, I did find one once on this forum, but a lot of those suggestions turned out to be bogus.
