Even when you don't want less +F, a good alternative to tail -f is tail -F. It survives log rotation, and the file being temporarily inaccessible:

    --retry
	      keep trying to open a file even if it is inaccessible when  tail
	      starts  or if it becomes inaccessible later; useful when follow-
	      ing by name, i.e., with --follow=name

    -F        same as --follow=name --retry
