Marina Investment Feasibility: Site, Capacity, Capex/Opex Modelling

Marina investment feasibility is the study that tests a marina project technically, commercially and financially before it is funded. It brings together site selection, berth capacity, capex/opex modelling, permit and concession structure, and demand analysis. This guide explains how the financing side reads a marina feasibility study.

Site selection

A marina's financeability largely begins with the site. The core criteria the financing side examines:

Natural shelter: Bay, wave and wind exposure; breakwater needs drive capex directly
Water depth: Dredging requirement, draft suited to target boat sizes
Land access: Road links, parking, airport proximity
Market proximity: Closeness to demand basins and charter routes
Competitive density: Existing marina supply and occupancy in the region

A weak site makes even a flawless financial model look risky.

Berth capacity and mix

Capacity planning is the heart of feasibility. It is not a single number but a berth mix:

| Berth type | Length range | Revenue profile | |---|---|---| | Small | 8-12 m | High volume, low unit revenue | | Medium | 12-20 m | Balanced demand and revenue | | Large / superyacht | 20 m+ | High unit revenue, narrow demand |

The mix is optimised to the target market. A superyacht-heavy marina produces higher per-unit revenue but is more exposed to occupancy swings.

Capex and Opex modelling

Capex (investment) items

Breakwater, quay and pontoon structures
Dredging and seabed works
Service building, social facilities, parking
Utilities: electricity, water, wastewater, fuel line
Permit, advisory and engineering costs

Opex (operating) items

Staff and management
Energy and maintenance
Annual periodic dredging
Insurance and concession share
Marketing

The financing side reads capex for the size of the repayment plan and opex for the sustainability of free cash flow.

Permits, EIA and concession

Marina projects are intertwined with heavy regulation. The permit timeline must be clarified at feasibility stage:

EIA: Months to years; defines the project's initial risk
Coastal fill permits: Under the Coastal Law
Concession period and rights: Caps the repayment tenor
Fuel-station permit: A separate process if it is an ancillary revenue item

No financing commitment forms until permit risk is clarified. Missing permits are written as drawdown conditions.

Demand analysis

Revenue projection rests on demand analysis:

Regional boat stock and growth trend
Charter-operator density and annual-package potential
Transient (visiting) boat traffic and seasonality
Competitor marinas' price and occupancy data

The financing side typically builds the repayment plan on a conservative case and runs a stress test asking whether debt can still be serviced if occupancy drops to 60%.

How financiers read a feasibility study

| Assessment area | What they look for | |---|---| | Site | Natural shelter, proximity to demand | | Capacity | Berth mix suited to the market | | Capex/Opex | Consistent, verifiable item list | | Permits | Clear timeline, low delay risk | | Revenue | Conservative, stress-resistant projection | | Concession | Period and transfer rights aligned to tenor |

A feasibility study prepared by an independent advisor directly raises the financing side's confidence.

Frequently asked questions

Who should prepare the feasibility study?

Ideally an independent technical and financial advisor. The financing side trusts an independent study far more than a projection the investor prepares in-house.

How precise must the capex estimate be?

An engineering-based estimate is sufficient at feasibility stage, but the major items (breakwater, dredging, utilities) must be realistic. Variance is managed with a budget reserve.

Why does IRR matter in feasibility?

IRR (internal rate of return) shows whether the project is attractive to the investor and whether it can carry debt service. The financing side examines DSCR alongside IRR.

How does concession period affect feasibility?

The concession period sets both the cap on repayment tenor and the horizon of the revenue projection. A short concession narrows the window to recover capex.
