Product Overview
One Kayak, Two Weeks of Water: The Expedition Platform
Why expedition paddlers and stage-race organizers keep choosing the S18 EXP G2 - and why it is a proven reference hull for your custom kayak line.
The S18 EXP G2 is the expedition version of Stellar's benchmark 18-foot touring hull.
The same efficient glide that made the original S18 famous is retained, while the hull has been re-tuned for extra efficiency, stability and loading capacity - the three qualities that decide whether a loaded kayak still tracks straight on day nine of a crossing.
Four hatches open up 211 liters of organized storage, enough for multi-week self-supported trips or full race logistics. A full-length Kevlar® keel strip comes standard, protecting the carbon fiber hull on rocky launches, gravel beaches and the unavoidable groundings of wilderness travel.
For ultra-marathon kayak events and multi-day stage races, this combination - cargo volume, reinforced keel, predictable stability at speed - has made the S18 EXP G2 a recurring choice on start lines. As the authorized agent covering South America and Asia, we supply it wholesale and reproduce its expedition-grade DNA in OEM/ODM programs for carbon fiber watercraft brands.

Design Details
Every Detail Earns Its Place on the Deck
Expedition-First Hull Geometry
At 5.5 m long and 55.7 cm wide, the hull balances touring speed against real-world stability. The depth of 32 cm and generous cockpit volume (84 cm × 44 cm) accommodate taller paddlers - even with bulky footwear and drysuits - across a 1.5–1.96 m height range. The cut-away deck shape lowers effective windage in gusts, a detail coastal paddlers notice immediately.
Features That Survive the Trip
- Bow hatch + 126 L stern compartment: dry-bag-friendly volumes for camping and race support gear
- Day hatch & paddle recess: snacks, safety kit and spare paddle stay within arm's reach without opening main compartments
- Full-length Kevlar® keel strip: sacrificial protection for the carbon fiber bottom on rocky shorelines
- Rudder system: course-holding authority in following seas and crosswinds when fully loaded
- Ergonomic handles & bottle-holder seat pad: carry comfort and hydration on long stages
Why This Hull Works for Your Market
Expedition and ultra-distance paddling is a growing segment across South American coastal routes and Asian archipelago touring. Importers, expedition tour operators and race organizers evaluating this model can offer it as-is under the Stellar line, or commission a custom variant - adjusted hatch layout, brand colors, laminate schedule - through our OEM/ODM service for carbon fiber kayaks.

FAQ
Q:What is the difference between the S18 G2 and the S18 EXP G2?
