Welcome aboard! Lots of H-34 guys here..
I am one of the almost bare bones guys so I won't be much help. I still have the original (1985) Signet Scientific instruments, but I sent them to Signet and had them rebuilt a couple of years ago. I am happy with their service. I have only a depthsounder, knot/log, and wind instrument. To that I have only added a Garmin chartplotter, and a Raymarine autopilot. No provisions for instrument-to-instrument communications. Boat is used for daysailing and coastal cruising in areas where we mostly don't have a lot of fog nor large commercial traffic. The commercial stuff is limited by our thin water so they are mostly in channels and the ICW.
Most new stuff is based on multi function displays with sensors based on the owners needs/wants..
Again, Welcome!
Right now I am bare bones, day sailing sailing on the Hudson River. Other than occasional barge traffic, it‘s pretty wide open. Right now the iPad with Navionics seems to work just fine, but I know I need to upgrade for the long term. although, I am possibly looking to upgrade to a newer model maybe early 2000s.Hello and welcome to SBO Forums.
An interesting and open ended question for your first post. With “46 years of experience.” Sailing and a 34 ft Hunter (nice boat by the way) I’m a little unsure about what answer you seek.
How you plan to sail and where you intend to sail are important starting points.
For instance if you plan to circumnavigate the planet your needs would be very different from day sailing in Long Island sound only during favorable weather. This gets to the second part of the query
“asking for advice to update the system in a cost effective manner”Some sail bare bones with a paper chart and a compass. Others like the gadgets and won’t leave the marina without the latest FLIR internet integrated electronic hardware.
Where on the spectrum do you see your self?
Thank you for your response and I’ll check out the other threads you cited above.Welcome to the forum!!
Same question came up on these threads: Electronics Ugrades - best approach? | Sailboat Owners Forums , New electronics | Sailboat Owners Forums and Need Guidance - Electronics | Sailboat Owners Forums . You will get a lot of recommendations on the subject of upgraded electronics, manufacturer, models and pc-based systems. What electronics do you have now? Some considerations depends on the sailing/motoring conditions (fog, navigation channels, night) and amount of redundancy:
Navigation display with GPG, AIS, wind direction, sonar and radar with repeater at the navigation station
Depth indicator
Wind meter
Independent knot meter
Autopilot
VHF with DSC, GPS, AIS and hailer
I had Signet depth and speed on my 1987 Hunter 31 that worked well. Added a Garmin navigation display with radar, tick tac wind and Raymarine autopilot (my best friend). Since then, my Huntet 386 and 46 and Symbol powerboat all have mid-2000 vintage Raymarine electronics, which meet my needs, are reliable and likely good value for $$.......I am possibly looking to upgrade to a newer model maybe early 2000s
