Re: Stus-List C&C 35 Mark III

[Jim Watts via CnC-List]

Our boat sings also. On Shift, it's definitely the rigging. At certain wind
speeds and direction, there is a very noticeable hum. Lashing a boathook to
the port shrouds helps a lot, but sometimes nothing stops it.

Stus-List Singing Rigging

[G Donald Wagner via CnC-List]

A lot of boats sing at certain wind speeds
I believe it is caused by a phenomena known as "von Karman vortex shedding"You 
will find it described in many fluid dynamics treatises.

Stus-List Forward Hatch on 30-2

[Jim Reinardy via CnC-List]

 

Hi all,

 

Hope this is not a double post, but did not see an earlier version come
through.

 

I'm doing some investigation on why my forward hatch does not stay open by
itself reliably and found a crack in one of the hinges on the half that
attaches to the frame mounted to the deck.   This is the large square hatch
in the v-berth of my '88 30-2.   My best guess from searching is that it is
a Lewmar Rollstop model.  Lewmar and their dealers no longer have parts for
these.

 

Can anyone help me confirm that I have identified this properly and/or know
of a source for parts?  Plan B would be having HatchMasters rebuild it, but
looking for other alternatives as well.   

 

Thanks,

 

Jim Reinardy
