Any significant modification of your yacht will call for a re-assessment of the CE.

Under significant is to be considered anything which changes the characteristics, behavior or operation of the yacht such as:

• adding stabilisers
• adding a movable swim platform
• extending the hull
• installing wireless operation
• adding (temporary) tanks
• adding a deck or fixed sun protection
• storing heavy objects on the flybridge, when these aren’t in the original design
• making hull penetrations
• re-positioning your steering stand
• …

All above examples call for a recalculation of the stability together with a CE re-assessment.
Without it the flagstate and/or insurers can consider the yacht to be no longer compliant.
