Retrieving the line and letting it fall between my legs in loose coils works well. Take note to clear obstructions or stray ropes to avoid tangles and stopped casts. So effective is this technique, particularly on spooky species, that I've sat in the middle of breaking bonito for minutes at a time on several occasions. Schools can't be too far off, but if they're spotted within 50 yards and stay up for a couple of minutes, a sprint can reach them in time. Learn your local waters for likely fish-holding spots and the most productive tides.
Fish often work patterns as they follow the bait.
Make note of these and get ahead of the trend. You are forced to commit to a smaller area of water than anglers with power boats, but what you'll gain in stealth can be worth it when you pick your water carefully. Be sure to slow down before casting so that you do not over run your line. If your charge has been an excited run to quickly moving fish, you will have to really slam on the brakes. It is often necessary to take the tide and wind into account so that a slack line makes it impossible to detect a take or set the hook.
