USCG COI PARTY BOATS
Party Boats Built for Business, Designed for Fun
We revolutionized the industry with the first-ever Coast Guard certified-human powered party boat branded as the Cycleboat. In 2020 we expanded our commercial tour boat lineup to include several models of non-pedaling Party Pontoons and eye catching Palapa Pontoons (tiki boats). While we have phased out Cycleboat production, we continue to add new tour boat models and with 125 COI vessels under our belt, our expertise speaks for itself.
Tiki Boat Theme
The Ultimate Floating Oasis. Sculpin Marine’s Palapa Pontoons are the gold standard in tiki boats-designed for heavy-duty commercial use with a flair that turns heads.
Built on our proprietary pontoon design and topped with long-lasting, fire-rated synthetic palm fronds, these boats are durable, stylish, and low-maintenance. Plus, with everything built in-house, we can customize your vessel to match your branding and style perfectly.
Custom Party Pontoons
Your Vision, Our Craftsmanship. Designed for fun and built for durability, our Party Pontoons are available in all model sizes with a variety of layouts—typically centered around a stylish bar. Whether you’re launching a new water sports business or expanding your fleet, these party barges offer the perfect blend of functionality and entertainment. Explore the many customization options for colors, branding, motor setup, and premium amenities.

Engineered for Reliability and Seamless Excursions
Custom-Built COI Boats for Your Tour OperationSafety & Compliance in Every Build
All of Sculpin Marine’s current party boat offerings were expertly designed and dead-weighted by our naval architect and approved by the Marine Safety Center. Our streamlined build process contributes to our track record of on-time boat completions and seamless Coast Guard approvals.
- Sister Vessel Approval Process: By “sistering” to an already approved design hull structure and general arrangement, your boat can skip stability testing.
- Pre-Approved Electrical and Fuel System Plans: Plans specific to your boat are approved by MSC before your boat is complete which expedites final approvals.
- Final Acceptance Test: Construction oversight and a final acceptance test are administered by MSU Portland.
- Stability Letter: Stability Letters are be issued by the Marine Safety Center (MSC) within 30 days of the final acceptance test.
- Certificate of Inspection: A New-to-Zone inspection is performed at your operating location by your local OCMI, who will then issue your Certificate of Inspection (COI).
- Custom Arrangements: For those requiring a custom layout, for an additional fee we offer naval architect services, including Coast Guard approvals.
