Think his navigation system survived LOL - that was violent!
I'm always a little gun shy when parked next to a big sailboat in a marina during a thunderstorm. However, this looks to have ended well for the boats around the sailboat. Probably the jury is still out on that assumption however. Who knows what happened to the electronics on boats nearby when all that power went into the water.
I watched that photo for a minute or so and never saw a lightening strike. Wassupwidat?
The strike occurs at the .04 sec mark into the 15 sec video.
Wow, that's not going to buff out
My computer must be too darn slow.
Well that happened to the clothes hanger slipped next to me a couple of weeks ago and showered my boat with sparks and parts of the mast (so the folks on the boat behind me said). My boat is heavily damaged; all of the electronics, many of the systems, and engine electrical systems are damaged. Besides the extensive damage to the sail boat mine is the worst of a total of seven boats that were affected.
Anybody anywhere close to that will likely have a “side flash” insurance claim. Happened to a friends boat, the damage was extensive.
OH Boy, wouldn't ya know....only one sailboat within 500 feet of me and I share a dock with him
Here is what I'm learning about boat lightning strikes and limiting damage.
1. Make sure your boat's grounding and bonding systems are solid and well terminated to the underwater gear (dynaplate, struts, rudders, etc).
2. If you have network equipment (like GPS receivers) on the bridge roof consider some sort of an opto-isolator in the data cabling (like a Maretron NBE100).
3. Consider splitting your data network (NMEA 2000) power taps into zones (bridge roof is one power zone, helm is another, and engine room another).
3. install a surge protector or isolation transformer between the marina's power pedestal and your boat's power systems.
4. Pray to Jobu you will be spared; in the end there isn't a lot one can do for a plastic boat.
My 52DB did not take a direct hit but the EMP was so significant it took out just about every electronic device on the boat (including the engine ECM's and SIM modules); even the LED lamps and liquid level sensors on the holding tanks..... We are going to make a few changes like NMEA 2000 power zones and some isolators but all in all, everything else was in great shape; not much else can be done. The insurance company brought in a surveyor to go over the boat and damage; he confirmed there isn't a lot we could have done as the boat was in excellent condition.
It's always good to have one or two blow boats around for that propose .
