[TheForge] Way off topic: boat dock

[Bruce Freeman]

Will the barrels have bung holes?  Anyplace convenient?  I'm thinking
you could load ballast as you build. then  adjust it later to give the
desired boyancy.  Water could be pumped in or out.  Sand could be
poured in and vacuumed out (if it stays dry or is sufficiently wet).
