Gull Point Marina
Gull Point Marina is a concept web app we designed for a marina manager. It puts the slips, the service bay and the fuel dock on one screen instead of a notebook, a logbook and a separate register.
A fictional product exploration showing interface and interaction design. No live deployment or commercial results are implied.

Who Gull Point Marina is for
A marina with 120 slips on four piers, a service bay and a fuel dock, and the people who run them.
- The marina manager, who watches occupancy and leases.
- The dockmaster, who keeps notes on boats and owners.
- The mechanic, who works through the service tickets.
- Staff at the fuel dock, who log every fill.
Why a marina needs one view
A marina runs on small facts: which slip is free, whose boat is in the shop, how much diesel went out today. Kept in a notebook, a logbook and a register, they are hard to see together.
- See every slip and its status at a glance.
- Know which boats leave this week and which slips are open.
- Tie service, fuel and lease payments to the boat and its owner.
What we designed for Gull Point Marina
Dock map
Four piers drawn as rows of numbered slips, coloured by status: occupied, open or leaving this week.
Slip and owner record
The boat, the slip and the lease, the owner’s contacts, the stay history, the dockmaster’s note and the instalments due.
Service board
Tickets by boat with the issue, mechanic, status, labour and parts, plus parts on order with supplier and ETA.
Fuel dock log
Each fill with boat, fuel, gallons and payment, totals by payment method and the tank levels.
Seasonal leases and waitlist
Active contracts and payments, the waitlist by boat size, who is next in line and revenue by month.
How the marina team uses it
Start at the map
Occupancy by pier, the boats leaving this week and the slips open today.
Open a slip
The boat, the owner, the lease and what is still due.
Run the service bay
Tickets move from scheduled to done, with parts tracked until they arrive.
Log the fuel
Every fill is logged with its payment, and the shift total is ready to export.
Fill the next slip
When a slip opens, the waitlist shows who is next for that size.
How we designed Gull Point Marina
We followed one Thursday in September at a marina in Annapolis, with one boat in focus: Blue Horizon in slip C15.
The map comes first
Slips are numbered tiles grouped by pier, so the open ones and the boats leaving stand out.
One boat across screens
Blue Horizon links the slip, the owner, the service ticket, the fuel fill and the lease.
Money next to the work
Instalments, service totals and the fuel shift sit on the screens where the work happens.
Sizes that match
Piers and the waitlist use the same length bands: up to 30 ft, 31 to 40, 41 to 50, and 51 ft and over.
A closer look at the screens






What the Gull Point Marina concept does
- Shows every slip on four piers, coloured by status.
- Lists the boats leaving this week and the slips open today.
- Keeps each boat’s lease, payments, service and notes in one record.
- Logs fuel fills by payment method and tracks tank levels.
- Shows the waitlist by boat size and who is next for each pier.
Questions about this project
No. It is a concept project: a fictional marina we used to design the product. The boats, owners and amounts on the screens are invented.
