1. Also, reserve buoyancy  was increased to 20.6 %. 2. The double hull design had a reserve buoyancy  of 32.5 percent. 3. Some Group 2 boats were fitted with a bow fairing to improve reserve buoyancy . 4. This increase and the resultant reduction in freeboard decreased the vessel's critical reserve buoyancy . 5. The ships were also designed with a very large amount of reserve buoyancy  to mitigate the effects of flooding. 6. In yachts, a low freeboard is often found on IMO damage stability regulations due to increased reserved buoyancy . 7. Normally, in a surface engagement the superior armament and greater reserve buoyancy  of the destroyer would have been decisive. 8. Normally, in a surface engagement the superior armament, speed and reserve buoyancy  of the destroyer would have been decisive. 9. On the other hand, they have very little reserve buoyancy  and tend to dive under waves instead of piercing or going over them. 10. Larger dinghies are towed and should have reserve buoyancy , an automatic bailer, and a cover to prevent them from being lost at sea.
