What should i do for Jummah when at sea for 3-5 weeks?

As Salamu Alaykum, I am at sea for anything for 3 to 5 weeks as a fisherman, but I am also the only Muslim on the vessel. This has created a problem for me in that on Friday I am the only person present for Jumuah and as I understand it Jumuah requires at least 2 people in order to be valid. I am also aware that someone who misses three or more Jumuah salat in a row is considered to have stepped outside the religion of Islam according to most scholars. Due to the nature of my job, is the only solution that I should simply get a different job? Fi'Aman Allah
