I was told that about 40 miles is the limit for point to point shots for those big microwave dishes even (without taking the curvature of the earth into account). Not saying it won't work farther, but if you have a tower 300' tall, and a boat (vessel) that may be 10' - 40' tall; I don't know if that will work because of the curvature of the earth? With that, if you have a directional antenna on the boat, you will constantly have to adjust the direction to the base station because of waves and just orientation. If you are talking about oil fields, that is a different story because you can probably get something to work that distance reliably.
My opinion, but I don't think it is feasible.

Hi, There has one inquiry for range of 60 miles, with CPEs on 15 vessels which are floating units. The base station can be fixed location offshore with VSAT while offering 360 degree of broadcasting. Network is planned to carry only data packets while accessing the internet. Can above be done by using 802.11? Any other better solutions? Though 3G/VSAT are possible with monthly payment.
