Hey Moots, I just took a couple of photos for you. The quality is a bit average due to my cheap phone, but I think that you will get the idea.
In photo A of my really old bottom board, there is a gap under where the bees land. Bees will quite often fly into the space under the pailing floor as the cleat is set back from the very front of the bottom board.
In photo B, the cleat is right at the front. There is more landing area (vertical and horizontal surface) and the bees seem to have less trouble. I have seen plans for a hive stand with a sloping "alighting" board at the front which gives even more area for the bees to aim at. The Michigan Beekeepers Association have a plan for one of these on their web site called hive-stand_20110330.pdf
that you should be able to find without too much trouble.
We don't have skunks or bears in Tasmania, so hives are often sat on a few concrete blocks or bricks rather than a higher dedicated stand. Sometimes a couple extra house bricks can be placed in front of the bottom board to take the place of the purpose built hive stand like in the plan - keeps the grass back a bit as well. That works well if you only have a small number of hives. I have seen some people use a short piece of plank or ply wood to act as a makeshift landing ramp too. I have tried to demonstrate both these ideas in photo C (substituting wooden blocks for bricks in this case, but the light wooden blocks probablty wouldn't be heavy enough to stay put for long). A couple of tacks through the ply into the bottom board would be a good idea too.
I haven't tested to see if the bees get less lost if the hive is a colour other than white. I'll ask around , it would be interesting to know if a darker colour helps with their landing approach.
