How would you as a buyer handle a pre purchase survey in an area with sub freezing temperatures? A sea trial can't be performed because the bays are frozen. The engine can be run on land but not under load. A surveyor told me he can't perform a moisture test untill the hull and deck are at least 40 degrees for 48 continuous hours. He said that soundings from his plastic mallet will not detect delaminated sections if the core is frozen. Are there ways to continue the purchase process that may satisify both the buyer and seller. Buying in the north at this time of year can be challenging.
