Your boat deserves better
than a group chat.
AI that keeps your vessel and your
co-owners in sync.
Every shared boat comes with the same hidden friction — who booked which weekend, who owes what for the last haul-out, who's following up with the marina. Spliyt handles all of it automatically. Trips get scheduled, expenses get split, maintenance gets dispatched — and you get to focus on the part that actually matters. Cast off.
Co-owning a boat gets
complicated fast.
The vessel is the easy part. Keeping four owners in sync is where it gets choppy.
Prime summer Saturdays turn into a standoff, and the calendar lives in one owner's head.
Dock fees, fuel, and winterization get fronted by one owner and repaid whenever.
Maintenance windows slip by because nobody is actually tracking the meter.
USCG papers, the policy, and the survey are scattered the moment you need them at the ramp.
One calm place to run the boat.
22 management tools that replace the group texts, the spreadsheets, and the paper folders — all in one shared platform.
A calendar that ends the weekend standoff.
Every owner gets water time based on their ownership share. Book trips, swap weekends, and rotate the holidays — automatically. Two owners want the same Saturday? The rules decide, not the group chat.
- — Share-based time allocation per owner
- — One-tap swap requests and approvals
- — Holiday and peak-season rotation
- — Real-time availability for the whole group
Fuel, slip, and haul-out — split clean.

- — Auto-logged trips and engine hours
- — Expense and payment history
- — Ownership decisions and messages
- — Exportable for insurance or legal use
Leave the dock right. Return it ready.
Pre-departure and post-trip checklists make sure safety gear is checked, the helm is locked, and the bilge is dry — every single time. Assign tasks by role so every owner knows what's theirs before they step off.
- — Pre-departure safety checklist
- — Post-trip return-ready checklist
- — Custom items per vessel
- — Signed-off by each owner on exit
Managing a shared boat manually
costs more than you realize.
It's not just the arguments. Every group that manages a co-owned vessel without a system is losing time, money, and goodwill - steadily, every month.
Hours lost every month
Time Costs
Chasing payment confirmations. Coordinating the same weekend via text. Tracking down who called the marina. These micro-tasks add up to hours of admin that none of your co-owners agreed to do.
Money lost to disputes
Financial Leakage
A missed maintenance payment. An "approved" repair nobody recorded. An engine overhaul nobody remembers voting on. Informal co-ownership arrangements lose real money to poor financial visibility.
Relationships put at risk
Relationship Friction
Research consistently shows that co-ownership disputes are among the most damaging to long-term relationships. The boat becomes the thing nobody wanted to own together.
Every boat co-owner knows at least one of these.
Spliyt was designed around the real situations boat co-owners face - not hypothetical ones.
Major repairs go to a co-owner vote in Spliyt. Everyone sees the quotes, casts their vote with a set deadline, and the outcome is binding and documented. No more month-long email threads going in circles.
Pre and post-trip checklists - engine hours, fuel levels, safety equipment, hull condition - are completed digitally and time-stamped. Every co-owner can see them. No more disputes about the vessel's condition.
Spliyt's shared booking calendar handles overlapping requests automatically. Conflicts are flagged before they become arguments. A co-owner who can't use their slot can offer it to others through the internal marketplace.
Expense tracking in Spliyt shows every co-owner exactly what they've paid, what they owe, and what the vessel costs to run. Shared costs are split by ownership percentage and visible to everyone in real time.
22 management tools built for boat and
yacht co-owner groups.
Designed for groups who already co-own a vessel and need a better way to coordinate.
Not a charter marketplace. Not a buying platform. Pure co-owner management.
Shared Access Scheduler
All co-owners book their time on the vessel from one shared calendar. Standard requests are auto-approved; scheduling conflicts are flagged before they become problems.
Internal Time Marketplace
Can't make your booked week? List it in the internal marketplace and let another co-owner claim it. Or offer it to the group to offset running costs - no group chat needed.
Democratic Expense Voting
Engine overhauls, new equipment, extended lay-up - major costs go to a binding group vote. Set majority thresholds, configure deadlines, and let Spliyt enforce the outcome automatically.
Expense Payment Tracking
Moorage, insurance, fuel, maintenance - every shared cost tracked in real time per co-owner. See exactly who has paid, who owes, and what's outstanding. Automatic payment reminders included.
Maintenance & Service Scheduler
Schedule engine services, hull inspections, anti-fouling, and winterization through the vendor dispatch portal. Assign tasks to marina crews, set deadlines, and track completion.
Pre & Post-Trip Checklists
Digital checklists completed by the departing and returning co-owner - engine hours, fuel levels, safety gear, bilge status. Every check time-stamped and visible to all. No more condition disputes.

What boat co-owners say once they've
stopped managing manually.
"We co-own a 45-foot Catamaran with three other families, and the logistics can be daunting. Moving our onboarding to Spliyt makes the entire setup feel completely effortless—handling scheduling, common expenses, and routine maintenance trackable from the start. It is like moving from paper maps to GPS."
"The expense voting feature brings incredible structure to our partnership. We are currently finalizing our new marine electronics upgrade through an organized vote rather than an endless loop of unrecorded texts."
"The Time Marketplace platform makes it seamless to trade and coordinate calendar slots, ensuring everything remains visibly objective and fair between co-owners from the very first trip."

Split across a typical four-owner boat, the Standard plan comes to about twenty-five dollars per owner each month. Less than a single tank of fuel.
Your plan begins with a 7-day free trial. Credit card required · Cancel anytime before Day 8.
Built for the way crews actually share.
One flat fee, not per owner
Add the whole crew without watching the price climb. The boat is billed once.
You keep full ownership
Spliyt is software, not a syndicate or a club. Your equity in the vessel stays entirely yours.
For any ownership group
Family boats, friend partnerships, or formal co-ownership shares. Spliyt fits them all.
Good to know.
Co-ownership means a group of people jointly own a boat and share its costs and usage. Spliyt handles everything — expense splitting, access scheduling, upkeep coordination, and governance — so co-owners can simply enjoy time on the water.
Spliyt supports any group size, though most boat co-ownerships work best with 2 to 8 co-owners. The platform automatically adjusts cost splits and access schedules based on each person's ownership share.
Fixed costs like slip fees, insurance, and storage are split automatically by ownership share. Variable costs like fuel can be tracked individually and billed only to the co-owner who incurred them — so you pay for what you actually use.
Spliyt's AI-powered access calendar distributes time fairly based on each co-owner's ownership share. High-demand periods like holiday weekends are rotated across the year so no one monopolizes the best dates.
You can list your slot on the Access Schedule Marketplace. Other co-owners can claim it, or you can offer it to approved third parties — any revenue generated offsets your share of running costs.
Recurring upkeep tasks are scheduled in-app, assigned to your preferred vendors, and tracked with digital completion checklists. Costs are automatically split among co-owners once the job is marked complete.
Spliyt automatically restricts non-paying co-owners from booking access time, voting on proposals, or initiating a share transfer. All restrictions lift once outstanding dues are cleared.
The Standard plan is $99/month ($990/year). No free tier — your plan begins with a 7-day free trial. Credit card required, cancel anytime before Day 8. Spliyt never takes a percentage of your asset value or co-owner payments.
Your shared boat, finally drama-free.
Start the free trial today and have the calendar, the ledger, and every document squared away before the season opens.
