[Alberg30] Success with seacock change while afloat

[Hugh Freebairn]

Can you please go through a blow by blow recount of the procedure you used?  
Previously there was a description using a piece of string and rubber ball 
but that didn't make sense to me.  If you used that or some other method can 
you please describe it in detail?

>not a true seacock) until next spring's haulout.  That change involved a
>somewhat greater volume of water (maybe 1.5 gal) but at a bit less force.
>It went smoothly.

>There was a beautiful color of the  sea through the hole in the boat bottom
