All weight dispositions (for example installing a fishing tower or radar, and engine replacement) can have a significant impact on the stability, trim, and performance of the boat.
- 
                The bilge water level needs to be kept at a minimum. 
- 
                The stability of the boat is compromised if any weight is placed in a high position. 
In stormy weather, all hatches, compartments and doors must be kept closed to minimize the risk of flooding.
Breaking waves represent a significant danger to stability.
To avoid the risk of flooding, always keep the seacocks closed when not in use (for example, the seacock for the toilet’s flushing water).
