Through Hulls

This is I think the final through hull.  I wasn't sure whether to bother with this, but in the end its probably better to fit it now and possibly not need it rather than mess about fitting it later.  It’s a through hull for the “psub standard” SUBCONN electrical bulkhead connector.  7/16 UNF thread which I started on the lathe and will complete the tap once its welded in. 

I have an idea that I will probably use two pins for for the depth sounder and switch the other two between VHF and underwater communications.  But I haven't decided finally on all that yet.  I have four high power pins spare on the front endcap connector.

I wasn't quite sure where to put this part either.  It might have been better on the rear endcap, but in the end I plumbed for the middle of the underside between ribs five and six simply because its easier for welding.  Depth sounder and underwater comms will be best placed underneath but VHF might be awkward.  We’ll see.
