Hi, I am trying to show service area reachable by boat at sea. I have a point on land as a boathouse I wish to be able to determine how far the boat can get in a given time at a give speed in all directions taking into account obstructions (headlands, reefs etc). Has anyone done this or something similar? If so how!? Thanks.

Do you have a network dataset to model the sea lanes, etc or just plain sea? If you do not have a network to use in this case then i suggest you look at Spatial Analyst for using a raster surface and look at the Euclidean Allocation or the Cost Allocation functions:
