Considering the alternatives. looking at 2.8 and downloaded latest ver.
The mesh size on maritime routes is the most important factor.
So using 2.8 opened the 20 km mesh of the river Wyre from 2.79b. So the maximum mesh size does not seem to be a drawback but no idea what to do next. Downloaded the 50meg help manual.
A possibility is to make the areas around the UK coastline using 2.79b, 3DEM and blender script for srtm. Maybe take a couple of hours for each. Build up a large stock of the BASIC routes
I dont know what the maximum route size would be for 2.8. Twenty km. seem OK but maybe investigate up to 50 km. A lot of the routes can be a flat seabed plane of a few vertices like the Isle of Man I made at 45 km with 2.79b.
As regards forum interests even if neglible or nil, I need to make the routes so they are mainly of interest to myself and they work OK.
Then as mentioned decide about renewing the domain contract in a few months. in the meanwhile I can put back the 3 routes online, up to Silloth and also Isle of Man. There are a few ways to make these routes so will also see what 2.8 has to offer…very slowly but at first sight not optimistic.
I think first sight will be enough though as regards making maritime routes as my opinion has now moved on after a few hours with 2.8.
The three routes are back online and looks like keeping to 2.79b will be more than enough for me and for the maritime world.
The first 3 routes are reasonable and minor updates made.
