The Town Of Nahant realizes that mooring loads are variable, that it is impossible to say that all boats of equal length require the same size mooring, and such standards can not be applied to all boats.

The Harbormaster of his/her designee (upon harbormaster approval), reserve the light to require a boat owner in increase the minimum mooring standard for any vessel should they feel the minimum standard would be inadequate for the vessel because of unusual design, such as but not limited to, excessive weight, windage, or draft.

Furthermore, the Town Of Nahant shall not be held liable for any damage inflicted if a minimum standard mooring falls.
