This summer, we will roll out two new services at OHM.
Tell us what you need the day before you need your boat and we will have it on your boat the next day. Is it Ice, water, food, parts,
something from the retail shop or a service? If you’d like your boat fueled prior to your arrival, just ask and consider your tank gassed up and ready to go! The cost is $60/day per boat plus item(s) requested.
We’re offering a new service where every Thursday we will:
• Start your boat
• Check all systems
• Make necessary repairs after discussing them with you
The cost is $215.00 per month or $60.00 per check.
Would you like your boat cleaned on a weekly or monthly basis? All cleaning and detailing cost are on our 2017 OHM service rates.
