It seems that beverage can work well close to salt water. Eu Beverage at VE1ZZ runs over poor ground (rocky terrain) and is terminated on the SS hub cap in the water. That one beats phased and staggered Beverages.

Lossy ground underneath the Beverage seems to complete the travelling wave antenna circuit, providing wave tilt. 

Verticals and loops should also perform well at the water's edge.
