Vindicated.....
When someone buys a boat in a slip, the slip will convey with the boat, (if the buyer wants the slip) as long as the new owner passes the litmus test of Wahweap Marina. I've been a part of 2 sales of houseboats in Wahweap Marina. Both buyers would not have bought the boats had the slips not went with the boat. Once the approval process is complete and the new owner takes over, he or she can put in a different boat if it fits in the slip. You can't put a 50 footer in a 30 foot slip but other than that, you can put a different vessel in that slip if it's registered, properly insured and approved by the marina.
