Oars - We are still using some which Robin already owned.  Dimensions are not ideal, but OK to get us afloat before winter.  Tips - (1)  Do online research for correct leverage, etc. (2) For rowlock bearings, consider bronze bushes instead of megga expensive, and rather chunky off-the-shelf ones.

Spars - Our bowsprit, boom, yard and mast were all spruce.  In each case two pieces bonded together with the grains suitably disposed to minimise subsequent bending.  To provide a flat "bed" for bonding the boom and yard we used the two (not-yet-bonded) mast sections on edge, and loads of clamps. The ambient temp was pretty good at the time.  The bonded yard became the flat bed on which the mast was bonded.
Shaping them - If you're happy with your boom, repeat!

Rudder - A pic on the Proteus page shows our rudder with grooves across it.  It includes some explanation of my method.  What is not mentioned is, I determined a desirable aerofoil section (online) and created several gauges to judge how much to plane/sand off in what I called "Phase 2".
The Centreboard was shaped in a similar way.

Casting lead in the rudder - See video on the same page.

CB Case - The basic assembly was as per Vivier.  We embodied some mods later.  (Three lines in the current version of the Mods list, and pics on "Proteus" page.)

Shelf - Is currently only conceptual, not even embryonic, though we have the materials.  It is to be sheltered below the foredeck but fairly low, providing stowage for the anchor and a dry place (out of the rain anyway) for sundry kit, refreshments, etc.

Aft footrests are associated with do-nuts.
Our forward footrests are bonded to the deck as per Vivier.
We decided to keep the aft foot-well clear.  Our aft footrest is a removable transverse bar - Stowed, when not wanted, through the (added) forward-facing hatch in the port-side locker/buoyancy.  The boat-hook and bowsprit also reside here.
Do-nuts are hardwood annular rings bonded to the inboard faces of the aft lockers.  Position was judged to provide comfortable rowing position.  I designed one of the do-nuts to open, yet without any removable parts, to allow mounting & de-mounting of the foot-bar.  Pics will eventually be on the Proteus page.

Sail supplier - We chose James Lawrence (guided by Mike and Sarah's experience).  For other sources see John Shelton's blog "Boudicca", and Port-Na-Storm's input on UKHBBR forum, or ask them.

Trailer - We used Admiral, as did our friend who built the “Goat” (also featured in Watercraft”)  Seems a good, solid, functional trailer and launching trolley.  Shaped to suit Morbic.  Decent mudguards, with useful forward-facing white lights.  Decent lighting board.  The latter will eventually be supported on a combined transom mast & light-board support.  
Only two resolvable "design-errors":-
(1) On ours we have to remove the dolly wheel between, using it to move the trailer, and using it to move the trolley.  Manageable, but not operationally ideal.  I have a solution in mind.
(2) When towing, the under-face of the forward end of the trolley frame bangs on the upper face of the trailer frame.  Padding (rope or rubber?) between the faces, and firm lashing provide some relief.  This may be common to all trolley/trailer combinations.
Don't let the above put you off.  Doubtless you'll shop around.
