Shadow - I think at some point you should haul out
and do it properly. You want to get all that old stuff off, you want to get a good look at your hull
and you probably want to get all the thru hulls replaced.
You might even have some shaft work
Save up your pennies, dive on the boat
for now but get everything under water
squared away with a good haul out where you get all the work
done at once.
