Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates.
1 Piling docks, perhaps the most popular type of permanent dock, usually cost about $20 to $40 per square foot. That includes installation but not fancy features such as gazebos, rails or lifts. Those features can raise the price to $60 per square foot.  Adding a boat lift usually costs an extra $5,000 to $7,000.
Canoe or kayak trailers cost $600-$1,500 for a single-boat trailer and can cost $2,000-$5,000 or more for a trailer with racks to hold six or up to 20 canoes or kayaks. For example, the aluminum Trailex UT-1000-6-04 canoe trailer can hold six 18' canoes, has a 1,000-pound capacity and lists for $2,529.
