Thank you, and good morning, everyone, and welcome to our First Quarter 2021 Earnings Conference Call and Webcast. I'm Michael Jolliffe, the Board Chairman of StealthGas. And with me on our call today is Harry Vafias, the CEO of StealthGas; along with our Finance Officer, Fenia Sakellaris.
Before we commence our presentation, I would like to remind you that we will be discussing forward-looking statements, which reflect current views with respect to future events and financial performance.
At this stage, if you could all take a moment to read our disclaimer on Slide 2 of this presentation. Risks are further disclosed in StealthGas' filings with the Securities and Exchange Commission. I would also like to point out that all amounts quoted, unless otherwise clarified, are implicitly stated in United States dollars.
Slide 3 summarizes the key highlights of our first quarter 2021 results that we released today. Although, we concluded a fair amount of new period charters, these slightly improved market conditions were not reflected in our revenues and profitability. Our performance remained quite similar to the fourth quarter of 2020 as we still chartered a high number of our vessels in the spot market, thereby facing high voyage and off-hire costs.
Indeed, in this first quarter, our spot days were equivalent to the full operation of 13 vessels in the spot market. The increase in bunker costs, along with the fact that we operated 2 of our product tankers throughout this quarter in the spot market, led to a sharp rise of our voyage costs, thus suppressing our spot earnings capacity even further. We do look at autumn with cautious optimism. As the global vaccination process accelerates, this gives us hope for a more substantial market recovery.
In addition to this, our market fundamentals remained strong with a low order book and a heightened demolition activity, thus assisting our segment even further. We believe that the combination of these parameters will most probably lead our market rates to pre-pandemic levels. However, the speed and timing of this anticipated recovery still remains uncertain.
Focusing on our operations, our fleet utilization for quarter 1, 2021 was 98.7%, with about 50 days of technical off-hires, mainly as a result of the drydocking of one small LPG carrier. In terms of our operational utilization, this came in at 93.1%, mainly due to more than 15 of our ships operating predominantly in the spot market, the equivalent to 31% of our voyage days and our unusually high spot presence.
Going forward, our fleet coverage has improved. We have 61% of our fleet days secured on period charters for the remainder of 2021, with total fleet employment days for all subsequent periods generating $87 million in contracted revenues. Including the time charter agreements of our joint venture structures, totally secured revenues increases to about $100 million.
We need to highlight that this quarter, leveraging upon our proven and longstanding sale and purchase experience and grasping the value momentum in the MGC segment, we took the strategic decision to sell the 35,000 cubic meter MGC carrier, the Gaschem Hamburg, owned by our MGC JV, a decision that proved to be profitable as the selling price resulted in an aggregate gain of USD 7 million. The sale was concluded within May 2021 and proved that our expanded presence and diversification within the broader LPG segment has indeed been both profitable and strategically sound.
Focusing on our financial performance, and compared to the first quarter of 2020, our revenues came in at $37.4 million, while our daily time charter equivalents decreased by about $100. As our spot exposure increased, so did the voyage costs incurred, thus suppressing our daily time charter equivalent earnings. With an EBITDA of about $13.5 million, our net income came in at $750,000, corresponding to an EPS of $0.02. Our capital structure remains healthy with low gearing and 0 capital commitments in the near-term future.
Slide #4 provides an analysis of our fleet employment. In terms of charter types, out of a fleet of 42 operating vessels, excluding our 7 JV vessels, we have 5 of these on bareboat, 28 on time charters and 9 in the spot market. Compared to our previous announcement, we managed to reduce our spot presence and fixed all of our tankers on period charters, thus narrowing our spot exposure to the smaller LPG market.
Indeed, we successfully concluded 10 new charters and charter extensions of short durations. We have 16 vessels concluding their period charters up until the end of 2021, which we view as a real opportunity. Our period coverage for the remainder of 2021 is in the order of 61%, while, currently, our period coverage for the second quarter of this year is in the order of 80%. We have close to $90 million of secured revenues and including our joint venture vessels, total secured revenues increased to about $100 million.
In Slide 5, I would like to provide an update as to our 2 joint venture performances. Our first joint venture, which comprises in its majority of small LPG vessels, currently has 3 out of the 5 total vessels under time charter contracts. The time charter contract for the medium gas carrier, the Eco Nebula, was recently extended for another 3 months where we recently fixed the Gas Haralambos on a 1-year time charter.
Focusing on our second joint venture, comprising of 2 medium gas carrier vessels, these are all under time charter contracts, thus producing steady cash flows. Following the aforementioned sale of the Gaschem Hamburg, which produced considerable gains, total free cash base within our joint venture arrangements has increased, and it is now in the order of about 40 million.
In terms of our fleet geography, presented in Slide 6, our company focuses on regional trade and local distribution of gas. This graph is a snapshot of the positioning of our LPG vessels, excluding our joint venture vessels, as of May 24, 2021. Currently, 16 vessels of the LPG fleet trade in Europe, 14 vessels in the Middle East, 5 vessels trade in South America and 3 in Africa.
I will now turn the call over to Fenia Sakellaris for our financial performance. Thank you, Fenia.
