@John6884 , you may want to be careful in how you plan on offering your property. “Packing them in,” will only lead to destruction of property and upset neighbors. Granted this is only seasonal but you ideally would like to offer a place that doesn’t come off as a frat house. The picture of your listing should include bedrooms/bathroom and or kitchen (if one is included). Listing details of any amenities and house rules. Personally, I wouldn’t post a picture of the boat unless you have wording or a disclaimer that the boat is not available for rental. Better yet, I would just remove the photo. I would highly recommend you have outdoor cameras installed (make sure to properly disclose them on your listing according to Airbnb guidelines). Cameras would help you monitor the property and protect you from any unauthorized parties and or unauthorized guest(s).
Start small so you can get a feel how STRs work and if successful, you can expand. Make sure you are in compliance with your local municipality rules and regulations as it pertains to STR (short term rentals) as Airbnb function is limited and does not monitor municipalities housing zoning regulations and /or tax collection/reporting requirements.
Best of luck!!!
