Buying Guide
Key considerations help you pick the right sliding base for your boat and usage scenario.
- Pedestal compatibility: Measure your pedestal post diameter (commonly 2-7/8″) and confirm the mounting pattern on the base you choose.
- Rail and plate sizes: Ensure rails (e.g., 15-inch rails) and mounting plates align with your bench or helm seat configuration.
- Movement range: Fore-and-aft travel length matters for reach to controls and legroom; some bases offer up to 7 inches of travel.
- Swivel and lock features: A full 360-degree swivel with a secure locking mechanism helps maintain seat position in rough water.
- Installation ease: Pre-drilled holes and pattern compatibility reduce on-site drilling and alignment issues.
- Material durability: Aluminum is common for marine use due to corrosion resistance; verify coating quality and fasteners.
- Installation space: Some bases are designed for bench seats; others suit helm or single-seat configurations. Ensure there is enough clearance around rails and seats.
