Yes, it can work. But since the gain isn't mentioned, nor the VSWR, I would never buy it. These antennas designs are commonly used in the 500-3000 MHz ranges for cellular telephone signals. Before we would ever use one in our systems for measuring cellular networks, we would get performance plots in azimuth and elevation vs frequency. This one shows a low gain across a very, very broad frequency range. Note the elevation is 0 degrees (horizon) in this plot. That would be your primary concern, but due to boat
heel, you should be concerned also with +/-40 degrees.
The same antenna, now plotted in a 3D plot of Azimuth, Elevation, and Gain at a single
frequency. Note that the gain is optimized for +30 to +60 degree elevations - that's for a car driving around below the cell site antennas. It still performs ok from -60 to +30 elevation, but there is a considerable loss of gain, especially below 0 degrees. Your antenna is likely to have similar characteristics.
