We also found out that by installing a martin house on a pole that was attached to one of the pipes that was holding up one corner of the boat hoist was a bad idea. In one year, due to either the birds landing/taking off or the wind blowing on the martin house, combined with the down pressure of the boat that post sunk 3" over the course of a year.
