Thank you for your replies and your additional information,
You are in a rather challenging situation with respect to getting paid for your services,
Where the parties to a contract/Agreement did not specify a specific time period or time limit in performing the obligations under such contract/Agreement, the law implies that the obligations of each party shall be performed within a reasonable amount of time. Since it is not worth your while to continue to perform services for the buyer at the rate of $15 per hour, and since you cannot unilaterally change the compensation, you can use his non-payment under the Agreement to permit you to take two different courses of action. First, you would send the buyer a "Demand Letter", in which you itemize the services you rendered and demand payment. This is a prerequisite to filing any lawsuit for payment. Your letter would also inform the buyer that he is in breach of contract, that you are declaring the contract null and void and of no further legal effect, thereby effectively rescinding the contract. Lastly, you would inform him in this letter that if you do not receive payment within "X" number of days, you will be forced to file a lawsuit for breach of contract. You would send the letter by Certified Mail, Return Receipt Requested, and a copy by ordinary mail. You would address these letters to him at the last address he gave you. You can also send him a copy by email, so you know that he will have notice of what you intend to do. The problem arises in that the lawsuit must be filed in a State where the Defendant can be served, or where the transaction occurred which gave rise to the cause of action. Unfortunately, the Connecticut Courts will not have personal jurisdiction over him unless you can have him served in Connecticut. If you can manage that, then when you obtain a judgment against him, you can ask the Court for a "Writ of Execution", give the Writ to the Sheriff, and ask the Sheriff to seize the boat and put it on the list for Sheriff's sale in order to satisfy the judgment you obtained against him.
If the buyer had not paid you the full purchase price and you were holding his Promissory Note and had a security interest in the boat, then I would have suggested that you foreclose on the lien created by your security interest and repossess the boat. However, this is not the situation and since the buyer paid you the purchase price in full, Connecticut law does not give you this right to "repossess" the boat and you would have to take the steps I outlined above and file a lawsuit against him.
if you rent the buyer the slip in which he keeps his boat docked and he has not paid, you can sue him for "past due rental charges" for the slip and go through the same procedure as I noted above.
I am sorry that I cannot tell you to just go ahead and take the boat, but I have an obligation to you to give only correct Answers, so I kindly requestthat you do not hold Connecticut law applicable to your case against me when rating my Service to you.
Please be kind enough to rate "Excellent Service" so that I receive credit
