The core idea is that your raft's size won't bring more sharks to the party - there's always just one persistent shark patrolling around, no matter how big you build. That said, having more edge pieces does mean more potential targets for our finned friend to nibble on so you'll want to plan accordingly.

Something interesting to keep in mind is that the shark's pretty smart about picking its spots, usually going after unprotected edges first but it'll definitely switch things up and attack inner sections if the outside is too well-defended. Foundation armor is your best friend here, especially along the outer edges where most attacks happen. Maybe worth mentioning that collection nets need extra attention since they're pretty important for gathering resources and the shark seems to have a taste for them.

A good defensive strategy is to start by armoring your outer foundations first, and make sure any important stuff like grills or nets has some protection. You can use shark bait to buy yourself some breathing room when needed but don't waste it - save it for when you're doing repairs or adding new sections. The shark's not actually trying to get you specifically, it's just following its programming to find the weakest spots in your build so keeping everything reinforced is the way to go.
