Drain Plug for Catamaran SL16, Hobie Cat, kayak...

Say goodbye to lost drain plugs with this Universal Drain Plug, designed to fit popular catamaran models like the SL16, Dart 18, Hobie Cat, and a few kayaks using a standard M16 x 1.5 thread. Lightweight, durable, and customizable, it’s the perfect solution for securing your boat's drainage system and avoiding water ingress.

Printed in a bright, easily visible colour, like the one shown here, this plug is easy to spot on the beach or in the sand, making it much harder to misplace. Plus, it’s so light that you might even gain some speed on the water (we like to think so!).

While PLA works perfectly well for standard use, we recommend printing in PETG or ASA for increased durability and resistance to UV rays, saltwater, and general wear and tear—ideal for long-term performance in marine environments.

Features:

• Cost-effective: Over 20x cheaper than standard commercial plugs.
• Universal compatibility: Fits SL16, Dart 18, Hobie Cat, and other catamarans with M16 x 1.5 threading.
• Highly visible design: Bright colours make it easy to locate on sand or in storage.
• Durable materials: Works with PLA, but PETG or ASA is recommended for longer lifespan in tough conditions.
• Lightweight: Reduces weight for better performance on the water (wink).
• Easy installation: Ergonomic design ensures quick and secure attachment or removal.
