Countdown to splash time.

There are a few critical steps to complete before I can put the boat in the water.
  1. install raw water intake through hull
  2. finish bottom paint
  3. install new hose and packing gland and flax packing
Then, I get to book the travel-lift appointment and when they have me in the slings, I install my DST800 instrument and slap on a bit more bottom paint. The next morning, the boat goes in and hopefully, all is well.

  1. Install raw water intake through-hull
    1. cut hole for through-hull -- 30 minutes
    2. sand exterior to epoxy around hole (just a circle) -- 5 minutes
    3. clean area with acetone -- 5 minutes
    4. cut through-hull to length -- 30 minutes
    5. dry install through hull for positioning -- 10 minutes
    6. drill 3 through-bolt holes, drill one, drop screw in hole, do next, etc. -- 30 minutes
    7. countersink holes, inside and out for good seal -- 30 minutes
    8. clean up both sides of hull -- 10 minutes
    9. apply sikaflex to screws and apply from outside -- 5 minutes
    10. apply sikaflex to flange and centre over screw holes -- 5 minutes
    11. tighten down screws -- 15 minutes
    12. apply sikaflex to through-hull and install, tighten -- 10 minutes
    13. clean up squeeze-out, inside and out -- 10 minutes
    14. apply fairing compound -- 20 mintues, overnight cure
    15. light sand fairing, clean with acetone -- 5 minutes
    16. Interprotect the area
  2. Finish bottom paint
    1. sand colloidal silica -- 10 minutes
    2. wash hull to remove sanding dust -- 1 hour
    3. fair patch -- 20 minutes, 6 hours cure time -- which means overnight.
    4. paint with Interprotect -- 45 minutes, a few hours to cure, ie: overnight.
    5. apply VC17 to rest of hull (except patched area) -- 3+ hours (end of day task)
  3. Install new hose and packing
    1. cut hose to length -- 5 minutes
    2. fit hose over stern tube -- 5 minutes
    3. install packing gland -- 5 minutes
    4. fit double clamps (4 total) -- 10 minutes
    5. cut packing rings (4 total) -- 15 minutes
    6. install packing rings -- 15 minutes
    7. tighten packing gland, not too much -- 10 minutes
It's a big list, but it is made up of a lot of small tasks so getting through it shouldn't be too difficult. This weekend will be a long one, however. I am goign to call to book my "mise à l'eau", ideally for Thursday evening to hang in the slings so I can drop Friday morning (the 12th).
