If you want to dig something like sand, you may need to add weight and add more reeving to increase the bite. Clams have some weird dynamics as they close. The more they close, the more the closing line lifts the bucket and it needs enough weight to counter that. Adding parts to the reeving can do the same thing but at the expense of speed and needing more distance to the boom tip to give the extra line a place to go unless the line off the drum is rove directly into the bucket. Looks like you've got a good start, though.
