Hydraulics, fluid dynamics and wine

This week we went to Santa Rosa California to spend two days at a training class learning about our hydraulic stabilizers and bow thrusters. The stabilizers are very important features that make our boat easier to handle and more comfortable in rough seas. They won’t save our lives, but they will make us less likely to want to die from seasickness.

A fin – one of a pair that are attached to the hull. Their hydraulic powered motors react to waves hitting the boat to reduce roll.
A tube with a thruster – we have one of these in the bow of our boat – huge assist for docking in wind!

The company ABT Trac holds these classes at their US based manufacturing company in California. The most amazing thing we learned was how service oriented ABT is – they have all the original drawings of our specific boat installation from 20 years ago, and we can call them at any time for help. We got the entire history of parts replacement and service for the life of our boat from the previous two owners. Now we are ready to do what’s required before we set sail on our voyage. We were truly impressed with ABT’s commitment to quality and reliability, and to their highly skilled long-standing staff.

Our instructor Eric was hilarious – I wish my Physics professor in college had Eric’s enthusiasm and excitement for fluid dynamics – I would not have struggled nearly as much! “Hydraulics is like baseball – everything goes back to home plate. “

In addition to learning the principles of hydraulic systems, we also got hands on mechanical experience taking the system apart to fix problems that are rare but COULD happen. Larry now thinks I am in charge of all maintenance.

I learned a lot doing it myself. Including the importance of LOTS of oilsorb towels available at all times.

We’ve ordered the list of spare parts that would be hard to get in Mexico. Now I just need to review where everything is on our own boat so I know what to look for when and if anything stops working.

In Sonoma County, if you are studying fluids you must study wine. We spent an enjoyable day with two tastings – Jordan Winery and Ramey. Perfect on a dreary rainy and chilly day in California.
