August 11, 2020 - Ingenuity at work - En-Route along the California Coast

We started receiving a text message from Nikolay with several photos.  Turns out he has been investigating the venting solution for the NEW Amertech seal that was just installed.

The instructions were not explicit regarding the venting resulting in the addition of an in-line valve to restrict water flow to the seal.  This was needed to keep water from overflowing up the vent line.  

After further communication with Amartech, they did not advise an in-line valve but recommended an automatic venting unit at the end of the vent line to prevent water from overflowing.  Another option is to vent the excess water over board.

Nikolay and I had discussed the previous day, and after reading their response he implemented an ingenious solution to further investigate the situation.  Or in his words:  Ingenuity- grew up and learned how to sail in Bulgaria. The nearest marine store was 300 miles away, there was international border with land mine field between us and the store... If you need it, make it work!

With this demonstration, exhibiting small excess flow, we agreed that the automatic venting solution is the best approach with the valve fully open (or removed).  It will remove the risk of inadvertent closure of the valve and eliminating the risk of damage to the seal.

January 11, 2023 - Van Isles, BC - On the hard

Image
January 11,  2023 - Van Isles, BC - On the hard Prior to arriving to Philbrook's we had started a dialogue regarding the work list, along with photos, to help with estimating and pre-planning.  This was useful as I was able to ensure that the parts (transducers and paint) were available and transported them with us avoiding any lead time issues or transportation cost associated with a border crossing. Our project manager, Ian, checked in with us first thing on Monday.  Ian promply started introducing us to the leads responsible for the work packages.  The whole process was very professional with good collaboration.  I was able to walk through each item of my list with the appropriate lead and discuss details.  Immediately after being hauled out we had people on the boat starting work on various projects. Servicing of the salon compressor was completed prior to haul-out with just a topping off of the refrigerant to account for the cooler NW climate, versus t...

June 3 - June 16, 2024 - Wrangell

June 3 - June 16, 2024 - Wrangell Calm morning and conditions for the transit to Wrangell pulling in between two fish boats.  We kept an eye on a boat in an ideal corner spot for us to type up on the opposite dock.  Soon they were on their way, and we repositioned to the opposite dock.  Once settled we began housekeeping chores so  Raven  would be ready for our return.  Geary, with help from Lois changed out the engine, generator, and get-home drive zincs.   Sylvia from Alaska Vistas gave us a lift to her office so we could make our deposit on our Anan Wildlife Tour in August.  Unfortunately, Ian Nelson of Nelson Diving, was ill and could not make our appointment for a bottom clean.  Brian Schwartz, Alaska Legacy Security, arrived and we set him up to monitor  Raven  while we are gone to Seattle from June 4 – June 16, retuning on June 17. Red Crossbill Replaced zincs ....
