Which rule determines the number of Thermal Protective Aids on lifeboats?

The number of Thermal Protective Aids on lifeboats is tied to the boat’s capacity to ensure there’s enough protection for everyone during rescue and exposure in cold water. The rule uses ten percent of the lifeboat’s capacity, but it never goes below two items. So you take the larger of two or one-tenth of the capacity, rounding up to whole units if needed. For example, a 20-person lifeboat needs 2 TPAs (10% = 2). A 50-person lifeboat needs 5 TPAs. A 12-person lifeboat would be 1.2, which rounds up to 2, and the minimum applies, giving 2. This approach scales with boat size while guaranteeing a practical minimum. Other options don’t fit because they ignore scaling with capacity or set an arbitrary fixed amount that could be insufficient for larger boats or unnecessary for very small ones.
