Ocean Transport Modalities: RoRo vs Container vs Flat Rack
Shipping a boat across international waters requires matching your vessel's physical footprint to the appropriate maritime cargo method. The three primary commercial ocean shipping modalities each have distinct pricing structures, maximum dimension allowances, and handling procedures:
Roll-On / Roll-Off (RoRo)
Best for trailerable boats and cruisers up to 45 feet. The vessel is secured onto its road trailer or a heavy-duty port mafi trailer and towed directly into the enclosed vehicle decks of a specialized car carrier vessel. Cost averages $3,500 to $9,500 depending on total cubic volume.
Enclosed Ocean Container (FCL)
The most cost-effective and secure method for vessels under 7 feet 10 inches beam and 8 feet 5 inches height. Boats are stowed inside standard 40-foot or 40-foot High-Cube intermodal containers, frequently on customized tilt cradles. Rates range from $2,800 to $6,500.
Flat Rack & Deck Cargo (LoLo)
Required for oversized beam powerboats, motor yachts, and sailboats exceeding container dimensions. The boat rests on a custom certified steel or timber cradle on a flat-rack container or secured on the weather deck. Costs range from $9,000 to $28,000+.
Major International Shipping Lanes & Transit Windows
Ocean freight transit schedules fluctuate based on trade lane demand, seasonal weather patterns, and major port congestion:
- US East Coast to Northern Europe (Rotterdam, Bremerhaven, Southampton): Transit time 12–18 days. High weekly sailing frequency from Port Everglades, FL, Baltimore, MD, and Savannah, GA.
- US East Coast to Mediterranean (Genoa, Valencia, Barcelona): Transit time 16–24 days. Popular corridor for seasonal yacht transfers between the Caribbean and Mediterranean cruising grounds.
- US West Coast to Australia & New Zealand (Sydney, Melbourne, Auckland): Transit time 22–32 days departing Long Beach, CA or Seattle, WA. Subject to strict biosecurity and hull biofouling washdown inspections upon arrival.
- US to Caribbean & Central America (Bahamas, Virgin Islands, Costa Rica): Transit time 3–7 days via regional feeder RoRo barges from South Florida.
Customs Duties, Import Taxes & Port Regulations
The ocean freight booking represents only part of your international shipping expenditure. When importing a boat into a foreign destination, international tax and maritime regulatory frameworks apply:
- Value Added Tax (VAT) / Goods and Services Tax (GST): In the European Union, imported recreational craft incur 19% to 22% VAT assessed on the CIF value (Cost of boat + Insurance + Freight). The United Kingdom assesses 20% VAT; Australia levies 10% GST plus 5% customs duty.
- CE Certification (European Union): All recreational vessels built after 1998 entering European territorial waters must comply with the EU Recreational Craft Directive (RCD) and hold verified CE marking certification before legal registration or resale.
- Terminal Handling Charges (THC) & Port Wharfage: Stevedoring, crane lift-off, and port discharge typically add $600 to $1,800 depending on destination harbor tariff schedules.
- Export Documentation: US Customs requires the original title or Manufacturer's Statement of Origin (MSO), notarized Bill of Sale, and an approved Electronic Export Information (EEI) filing submitted via the Automated Export System (AES) at least 72 hours prior to vessel vessel loading.
Cradle Construction & Ocean Preparation Standards
Ocean passages subject vessels to continuous multi-directional wave accelerations. Failing to adequately prepare your boat can result in catastrophic structural failure during storm transit:
- ISPM-15 Certified Heat-Treated Timber: All wooden transport cradles must bear the international wheat stamp certifying heat treatment (HT) against wood boring pests. Untreated lumber will be rejected or incinerated by port customs.
- Heavy-Duty Marine Shrink-Wrapping: Apply 8 to 10 mil marine shrink-wrap with integrated moisture desiccant bags and passive ventilation louvers to prevent mold and saltwater corrosion during deck stowage.
- Mast De-Rigging & Spar Lashing: Sailboat masts must be unstepped, spreaders removed, and standing rigging securely lashed to the mast extrusion with padded carpet wraps.
- Fuel Tank De-Gassing: Ocean freight carriers enforce strict hazardous materials policies requiring fuel tanks to be drained below 1/8 tank capacity with batteries disconnected and terminals insulated.

Frequently asked questions
International boat shipping costs typically range from $3,500 to $18,000+ depending on the vessel's length, beam, and shipping method. Enclosed 40-foot container shipping averages $2,800 to $6,500 for narrow trailerable boats (<7'10" beam). Roll-on/Roll-off (RoRo) ranges from $3,500 to $12,000 for powerboats and cruisers on trailers. Flat-rack or deck cargo for wide-beam yachts can range from $9,000 to $35,000+. Use our calculator above for custom lane-by-lane estimates.
RoRo (Roll-On/Roll-Off) involves towing a vessel on its road trailer or a heavy-duty port mafi trailer directly into the enclosed lower decks of a car/vehicle carrier ship. Container shipping loads the boat inside a 40-foot standard or high-cube intermodal container, frequently utilizing a custom tilt cradle to fit inside the 7'8" door opening. RoRo accommodates much taller and wider boats, whereas container shipping provides maximum protection and lower base rates for smaller hulls.
Import duties and taxes depend on the destination country and vessel age. Importing into the European Union incurs standard customs duty (0% to 1.7%) plus local Value-Added Tax (VAT, typically 19% to 25% calculated on the CIF value: Cost, Insurance, and Freight). In addition, boats built after June 1998 imported into the EU or UK require CE marking (Recreational Craft Directive compliance) or a Post-Construction Assessment (PCA).
Port-to-port ocean transit from the US East Coast to Northern Europe (Rotterdam, Southampton, Bremerhaven) takes approximately 12 to 20 days. US East Coast to the Mediterranean takes 18 to 28 days. US West Coast to Australia or New Zealand requires 25 to 42 days. Including customs clearance, terminal handling, and origin staging, total door-to-port timelines usually range from 4 to 8 weeks.
For RoRo transport, international ocean carriers and US Customs strictly prohibit loose personal belongings, household goods, tools, and extra gear inside the boat cabin or cockpit to prevent theft and comply with maritime security protocols. Factory gear, life jackets, and fixed electronics may remain on board if securely locked and itemized on the ocean bill of lading. For private container shipments, personal items are permitted but must be declared on the commercial customs packing list.
US Customs and Border Protection (CBP) requires: (1) Original Title free of liens or certified Manufacturer's Statement of Origin (MSO), (2) Notarized Bill of Sale, (3) Commercial export invoice, (4) Copy of owner's passport/photo ID, and (5) An Automated Export System (AES) Internal Transaction Number (ITN) filed with US Customs at least 72 hours prior to vessel vessel loading.
For RoRo transport, your vessel must either be on an operational, towable road trailer with working tires and bearings, or secured to a certified steel or timber cradle that port stevedores can lift onto a port mafi roll trailer. For container or flat-rack transport, a custom-built, ISPM-15 heat-treated wood or steel cradle is required to support the keel and hull during ocean swells.
