Geophysical Survey Vessels

Choosing the proper survey vessel is critical to the success of any marine survey. Sea Surveyor owns 4 custom-built survey vessels, ranging from 14-feet to 72-feet in overall length. Each of our survey vessels are designed to operate in a specific environment, ranging from rough seas found in offshore marine waters, to choppy conditions present in large harbors, to the calm waters of lakes and coastal lagoons. Trailers and tow vehicles are included with the 14’, 22’, and 26’ survey vessels for quick and inexpensive transport to the work site.
