Rummy
The 2nd hatch installed over the head causes a .25" dip at the port to
strboard centerline of the hatches
It goes away when I lower the mast. Said hatch went in In 03 when the
boat was recycled, it is an 86. The ex comp post is slightly aft and
to stbrd of the mast step. The shrouds were never overly tight on my
watch and I release the backstay tension when moored. I think I will
get a Loo's tension gauge this year and set the tension per the
manual. In any case I think one more season of monitoring is in order
And welcome back!
