Fresh figures released by British Marine and Superyacht UK show that revenue rose 11.5% to £605m in 2015/2016, marking the industry's fourth consecutive year of growth.
However, Peter Brown, Superyacht UK chairman and salesman at yacht broker Burgess, said that "the decision to leave the EU is likely to dampen this growth".
Nevertheless, the news has buoyed industry sentiment, with 75% of Britain's superyacht companies recording positive outlook for the next 12 months.
"With the majority of members reporting high levels of confidence post-referendum, this is in stark contrast to the sharp falls in business optimism recorded in August among British SMEs in non-marine industries," the report highlighted.
The industry has managed to stay afloat in part thanks to its limited exposure to the domestic market.
"Recent years have seen greater demand for yacht sales from international markets, including Asia and the US," Richard Selby, international development manager for Superyacht UK and British Marine, said.
Meanwhile, the pound's post-Brexit drop has also supported turnover, strengthening the purchasing power of overseas customers.
Sterling has dropped around 11% against the dollar and 9% against the euro since the referendum result was announced.
About 72% of Superyacht UK's 250 members have reported a jump in business activity, up from 61% in the company's last survey.
It has helped drive up full-time industry employment by 4.5% over the past financial year, with over 4,100 people now employed by the superyacht sector.
Brown added: "With market dynamics strong, the superyacht sector is expected to continue to post positive revenue growth over the next 12 months."
