Product Overview
The ST19: A 19-Foot Touring Kayak That Changes Shape to Match Your Program
Assembled as a single, it paddles with the agility of Stellar's iconic S14G2. Add the second cockpit section and it becomes a true 19-foot tandem with a 256 kg load rating. No other touring kayak in this class works both sides of the fleet - and no other page on this site shows a boat that does.
The ST19 was designed for paddlers with space challenges - and for programs with fleet challenges. The story starts with an efficient, easy-to-paddle single that suits beginners and advanced paddlers alike. Then the modular deck changes everything: bolt on the second cockpit and the same hull becomes a 19' double with room for two paddlers, a child, or gear that would never fit a solo boat.
Built around a cut-away hull profile, sealed bulkheads and a retractable skeg, it is a fully functional touring kayak in either configuration - with over-stern rudder fittings factory-ready if your paddlers prefer a rudder. That is why urban paddlers, camper-van owners and rental operators all order it: one boat, two jobs, no second boat to store.
As an authorized Stellar agent and a carbon fiber kayak manufacturer ourselves, we can build your ST19 order - single-only, tandem-only, or a mixed fleet - and customize the modular system, deck layout and brand colors before the first hull leaves the factory.
Dual-Config System
One Hull, Two Personalities - How the Modular Deck Works
The secret is the bolt-on cockpit section: a bulkhead-stiffened deck module that mounts on precision screws and converts the boat in the time it takes to rig a paddle. Here is what each configuration delivers.
Mode 01 - Single Cruiser
Solo touring with S14G2-class agility
With the aft cockpit section removed, the ST19 paddles like Stellar's iconic S14G2: light on the water, quick to accelerate, efficient and easy for beginners yet responsive enough for advanced paddlers. The cut-away hull profile keeps the deck low and the paddle reach natural.
Cockpit: 33.8" × 17.3" (86 × 44 cm)
Feel: Agile, efficient, easy to paddle
Best for: Solo tours, training, urban paddling
Mode 02 - 19' Tandem
Two paddlers, 256 kg capacity, expedition load
Bolt on the second cockpit and the hull becomes a genuine 19-foot double. With 256 kg of rated capacity - the highest in the Stellar touring family - it carries two adults plus gear, a paddler and a child, or a solo paddler with expedition-level stores.
Capacity: 564 lbs / 256 kg (1+1)
Storage: 182 L sealed (57 L + 125 L)
Best for: Teaching, family trips, guided doubles

Build Options
Four Laminates - And a Recommended Configuration for Each
Because the ST19 can be paddled solo or tandem, the laminate choice shapes both the single-boat feel and the double-boat payload. We manufacture all four schedules in-house on this hull.
Industry Solutions
Choose the plan that suits you best.
Alpha
55.1 lbs / 25 kg
Woven Toray 3k carbon fiber over Nomex® honeycomb, clear-coated and heat-cured - extremely stiff, feather-light, and the easiest ST19 to lift and car-top in solo mode.
Best for: solo-first paddlers who lift alone
01
Excel
57.3 lbs / 26 kg
Heat-cured epoxy Kevlar® and glass over Nomex® honeycomb - stiff, light and economical. The value pick when a fleet wants performance without the premium build.
Best for: performance-focused single mode
02
Multi-Sport
59.5 lbs / 27 kg
Single-layer carbon & Kevlar® hull under clear gelcoat with an Advantage deck - built to flex and shrug off contact, rated for Class I–II moving water and shallow-water abrasion. The rare build that survives both a river trip and a rocky landing.
Best for: mixed-water programs & rentals
03
Advantage
61.7 lbs / 28 kg
Heat-cured infused epoxy glass with Soric® core - the puncture-resistant workhorse with the lowest lifetime repair cost. The logical choice for tandem units that carry maximum load day after day.
Best for: high-utilization tandem rentals
04
Configuration × laminate - the fleet recipe

| Excel | Great performance-per-dollar for solo fleets | Good stiffness for loaded tandem trips |
| Multi-Sport | River-tolerant solo boat for mixed-water guiding | Rock-shore doubles that take a beating |

OEM / ODM Service
Modular Bulkhead Engineering - We Build the System Your Brand Needs
The ST19's defining feature is modularity, and modularity is exactly what we customize. Our OEM/ODM scope on this hull turns a single SKU into a whole family of products under your brand.
Technology First
We offer a variety of transmission components
Bolt-On Cockpit Sections
Manufacture and supply spare second-cockpit modules with your inventory - dealers sell the tandem conversion as an aftermarket accessory, and your fleet can switch modes without buying whole boats.
Fleet Mix by Configuration
Order single-only, tandem-only, or a mix in one container. Because solo and tandem share one hull, bulkhead tooling and spare-parts lists stay identical across both product lines.
Brand & Deck Customization
In-mold brand colors, custom deck rigging, paddle-park and pump placements, and seat/brace options tuned for your paddler groups - configured before the first hull is laid up.
White-Label Program
Bring the modular single/tandem concept to your market under your own brand. We handle molds, bulkhead tooling, QC and container logistics; you own the product story.
We partner with carbon fiber boat and kayak brands, outfitters and rental operators across Asia and South America - your manufacturing partner from hull drawings to mixed-fleet containers, not just a supplier of finished boats.
Factory Strength
One Mold, Many Models - Derivation Is Our Manufacturing DNA
The ST19's modularity works because our production line is built for derivation: one hull tool, several deck configurations, and disciplined engineering gates at every joint that matters.
Final Solution
Bulkhead Seal Testing
Every modular section is water-pressure tested at the joint - both as a single hull and after tandem conversion - before it leaves the layup room.
Screw Torque Standards
Bulkhead section screws follow a written torque spec, so a field conversion is repeatable, predictable and never over-tightened into the laminate.
Dual-Form Strength Validation
Sample hulls are load-tested in both configurations; load ratings are certified against the tandem mode before series production is released.
FAQ
Q: Does the ST19 in single mode really paddle like the S14G2?
A: That is exactly how Stellar describes the design: assembled as a single, it performs like their iconic S14G2 - light, quick and efficient to paddle - while the longer hull adds the space and stability of a 19-foot platform. Beginners find it easy, advanced paddlers find it responsive, and both are using the same boat.
Q: How is the single-to-tandem conversion actually done?
A: The aft cockpit is a bulkhead-stiffened deck section that bolts onto the hull on precision screws. The conversion is designed to be done by a dealer or an experienced paddler using the documented torque spec - no cutting, no drilling, no lamination work. Under our ODM service, we also supply the second cockpit as a packaged accessory for your aftermarket sales.
Q: Does a 256 kg load rating make sense for a 19-footer?
A: It is the highest rating in the Stellar touring family, and it is exactly what the tandem configuration needs: two adults plus gear, or a paddler and a child, or a solo paddler carrying expedition stores. For rental and teaching operators, it means the same hull legally covers two-paddler trips without a second boat class.
Q: Will the bulkhead joint leak or weaken the hull?
A: No. The modular joint is a structural station with sealed bulkheads, and every hull is water-pressure tested at the joint in both configurations before shipping. Screws follow a written torque standard so field conversions are consistent. The load rating is validated in tandem mode, not just solo mode - the strongest case, not the easiest one.
Q: How does the ST19 compare with the ST21 tandem?
A: The ST21 is a dedicated two-person touring kayak built around racing heritage and tandem performance. The ST19 is the modular option: one hull that works as a solo boat and converts to a tandem when needed. If your program runs dedicated doubles all season, the ST21 is the specialist; if you need one boat to cover solo tours, doubles and teaching, the ST19 is the flexible answer - and many fleets carry both.
Q: Which B2B buyers typically order the ST19?
A: Three profiles dominate: rental and teaching operators who need solo/double coverage from one SKU; outfitters with limited storage who want a two-product line without two warehouses; and brand importers who want to launch a modular "convertible kayak" concept under their own label. We quote per configuration mix, and the bulkhead accessory can be ordered alongside the hulls in the same container.
