Re-profile keel: (decided against for this year, but I did cut the templates and sized things up)

• 

• 

• 

• 

• where: t is the thickness in percent (.09 for NACA 0009, .12 for NACA 0012, etc.) and x goes from zero to one as stations (percentage of length) along the chord.  y is the distance from the centerline (above or below).

• 1. Establish overall chord line length (c); our example is 24".

  

  2.Refer to NACA 0012 Basic Thickness Form. Calculate and mark the station locations (x) which are a percentage of the overall chord line length, measured from 0%.

  

  3. Calculate and mark the y dimensions (thickness from the chord line) at each station.

  

  4. Duplicate the y dimension points on the other half of the foil.

  

  5. Connect the plotted points with a batten or ship's curve.

  

  6. Lay out the leading edge radius. The actual radius is a 90 degree segment of a circle drawn tangent to #O, bisected by the chord line. Its radius is 1.58% of the chord line length (c).

  

   

 Repaint and service Engine.   Pulleys and impeller need servicing.

 Replace cockpit controls panel.  The old panel impossible to read underway.

 Service forward/reverse shifter.

 Sanitize holds (done)

 Repaint Deck

 Replace Crank Battery (done)

 Replace Mainsheet (deferred)

 Refurbish mainsheet hardware (done)

 Refurbish/replace lifeline hardware (next year)

 Redo Icebox insulation  (in progress)

 Add new 125% Genoa (done)

 Clean/repair mainsail (done)

 Install Bimini top (done)

 Consider dodger options (hard vs. frame)

Rebuild raw water pump (done)

Replace mixing elbow (done) on the Yanmar.   Required on account that the engine stalled and would not stay running.  After inspections found it to be nearly completely plugged up.

Mast-gate - Also known as Sailgate, designed to keep the mainsail slugs in the track when passing through the gate. (done)
