Buying Guide — Key Considerations For Aftermarket Swim Platforms
- Material and corrosion resistance: Stainless steel (304/316) and teak are common, with stainless offering strength and saltwater resilience, and teak offering premium aesthetics with durable performance.
- Mounting compatibility: Check deck type (flat deck, transom, or under-platform) and existing accessories to ensure proper fit and load capacity.
- Storage and stowability: Telescoping ladders and foldable platforms save space but require clear storage room on board and smooth operation.
- Load capacity: Consider total weight of users plus gear. Heavier ladders are better for divers and frequent swimmers, but may require sturdier mounting.
- Maintenance needs: Teak requires periodic oiling or sealing; stainless steel needs occasional cleaning to prevent staining; inflatable platforms require puncture checks.
- Intended use: Choose between fixed platforms for constant access or portable/inflatable options for temporary docking and variable setups.
