[Public-List] Cockpit deck core job

[crufone at comcast.net]

Jeffery, 

Gord's is a liner boat and as such I believe that his boat treats the rudder stock as it exits the cockpit sole differently. I don't believe that Gord's boat has the 'volcano' of fibreglass around the rudder post as do our older non-liner boats. Perhaps Geroge or Gord can verify this. On #133 there is quite a raised 'volcano' hump of glass structure around the rudder post as it exits the sole. The bronze bushing is attached into the top of this raised area.......perhaps some 3" above the cockpit sole.  This helps prevent average amounts of water from going down the rudder tube in average conditions. If the cockpit were flooded water would rise above the 'vlcano' and also go down the rudder tube and wet the exposed core.

Gord, 

Does your boat have the little fiberglass volcano that rises up under 
the tiller where the shaft meets the tiller? Sounds like this came out 
intact and you were able to completely able to reuse? For the core, a 
solid piece of plywood? Or cut up into sections? 

Good for you on jumping into this. It's on my list, but keeps getting 
bumped back down by other projects.
