- Going concern
- Affirmed
“The directors have prepared detailed long term financial projections. Taking into consideration the net asset value, liquidity, trading prospects and obligations of the company and group, the directors believe it appropriate to prepare the company and group financial statements on a going concern basis.”
Significant events
- “Following our successful competitive contract award in FY2022 for the charter of three vessels to undertake fisheries inspection services in international waters throughout Europe and North Atlantic, this sector now represents 38% of group vessel employment and profitability in FY2024.”
- “The directors welcome Cyan Renewables as the majority shareholder. With its strong financial capability, Sentinel Marine is now in a much stronger position to grow by investing in new tonnage to target these markets, especially in offshore renewables.”
- “During the year the company secured a new USD6.6m loan facility.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
