You can write either but we recommend Master as it leaves no confusion for the USCG evaluators that you were running your own boat.
If you are have command of the vessel you are serving as Master. This is defined by the USCG in 46 CFR § 10.107. You should always write in Master if you were the person in charge of the vessel. Captain will work but Master leaves zero room for interpretation by the USCG evaluators.
If you are using mmseas.com and you own the vessel, you can create perfect CG-719S forms inside of the app.
