we are looking at a 2017 Ranger21EC tomorrow. We have had boats for years but this will be our first experience with a Ranger Tug. What are experiences on getting a survey or sea trails done, worth the money and time? The boat looks pristine and has been stored inside. 460hours so barely used. It is hard to do normal activities with Covid, so the seller may not want to take us for a sea trial. What are problem areas that a survey could expose if any? Thanks for all input to make our decision easier.
