Wet Slip Rentals
Our wet slips at Pioneer Marina are designed for vessels with a length overall between 20 and 45 feet and a maximum beam of 13’6 feet. With no height restrictions, our slips accommodate a wide range of boats. Boaters enjoy direct access to freshwater, electricity, Wi-Fi, and pump-out services – all available right at the dock. The marina is also equipped with a 25-ton travel lift capable of handling vessels with beams up to 15 feet, as well as a jib crane that assists with lifting sailboat masts and motors. These convenient services make Pioneer Marina a reliable choice for seasonal and long-term slip holders who value comfort and support.
Transient Slip Rentals
Our transient slips offer a welcoming and well-equipped option for boaters just passing through. Like our wet slips, they accommodate vessels between 20 and 45 feet in length with beams up to 13 ‘6 feet and no height restrictions. Each slip provides easy access to shore power, water, pump-out services, and Wi-Fi to keep your stay as comfortable and efficient as possible. For those who need extra assistance, our 25-ton travel lift and jib crane are available. Whether you’re docking for a night or a week, our transient slips offer everything you need for a smooth and stress-free stay.
