Bulkheads
Wood or vinyl?
Most coastal bulkheads are built from 2.5 CCA treated lumber or vinyl. Wood is economical, does a fine job against erosion, and the treatment protects it from parasites in the water. Vinyl costs a bit more, but it resists chemicals, mildew and marine borers, and it flexes with high-pressure waves instead of breaking apart or caving in.
Boat lifts
Size the lift right
Weigh the boat with its engine and a full tank of fuel, then choose a lift rated above that. A 5,000 lb boat needs at least a 6,000 lb lift. Aluminum lifts are built from 6061-T6 alloy; hot-dipped galvanized steel lifts rust over time, especially in salt water.
Hurricanes
Ready for a storm
Set the lift so that, at its highest, the boat sits well above the dock and seawall. When a storm is coming, secure the boat to the lift and fasten the lift in position with lines.
