The Hatteras Classic Club learning sessions started this morning. Our first speaker was Bill Brandon, an ABYC Certified Marine Electrical and Systems. He has been National Marine Electronics Association trained: Advanced Electronics installations. Advanced NEMA 2000 Networking.
Bill’s presentation was about ELCI breaker requirements from ABYC. Electric Leakage Current Interrupter is required in all NEW marina electric installations for shore power. The National Electric Code requires either an ELCI at the pedestal or at the transformer for the dock. Bill went though an elementary explanation of “stray current” on boats. Then he discussed having an ELCI installed on our boats within ten feet of the electric coming onto the boat. Bill also discussed new Isolation Transformers as a much more expensive but comprehensive “treatment” of the electric current coming on your boat. Bill then made a short presentation on the MMSI and DSC calling systems. There were lots of questions during Bill’s question and answer segment. A really interesting presentation. ABYC.org “search” for “certified electrical technicians”.
Our next speaker, who has been in the marine paint and coating industry for many years, is George Dunigan who is currently with Pettit Paint. He said to choose the right paint we need to start with where is the boat, what kind of boat, how fast do you drive the boat, how much is the boat moved and how much is our budget. A discussion followed on hard versus ablative paints for the bottoms of our boats. One coat versus two coats. George talked about Pettit’s metal paint for props and shafts “Prop Coat Barnacle Barrier”. He recommended two thin coats on the metal. Then George led a discussion about Barrier Coats which most of us have had experience with because of the “Hatteras blisters”. Flexible Caulk was shown “Flex Poxy” For top coatings George gave a plug for Awlgrip as a great long term product.
The next presentation was from John Murch of Garmin. Eight foot accuracy now is available with the newer GPS with WASS. John’s presentation focused on the “new” capabilities of the new electronics. If we are happy with the equipment that we have, there is no reason that you have to change. Everything still works at the capability that was technically available at the time of manufacture. The new equipment can handle significantly more data than the old units. An example is fish finders. The traditional finder uses a signal that uses less information than is available now. The new technology is CHIRP or Compressed Hi Intensity Radiated Pulse, in which sonar emits a continuous sweep of the water. Clear Vu Sonar technology uses a High frequency signal plus a broad fan shaped sonar pattern to give a photographic quality image of the bottom in a “slice” pattern to provide hi definition broad view on both sides of the boat. Side Vu is another modern technology that is used when going slow. Forward scanning is also available but it is more expensive in the range of $1,500.. Multibeam or phased Array Sonar is even more data driven. The Panoptix Down 3-D images were unbelievable .A big change is Radar – Fantom Radar with Doppler which is solid state. A moving boat or “target” shows as green unless it is in your path in which case it shows as “red” on the screen. John talked about putting engine data onto the screen even on our old Detroits if we pay to have the data changed into digital data.
At 3:00 pm we board two Hatteras 53 Classic MYs "City Girl" and "Size Matters" to a trip to the Sagamore Distillery to learn all about making Rye, of course with some sampling. From there we go to Tidewater Yacht Service for a cook out that Tidewater is hosting for us.
Everyone is having a great time.
