Useful digital tools for boats


I jumped into the waters, I boat a sailboat.

Here is a selection of tools I find useful, mostly free stuff, leave a comment for referral 😉





Finding the maps files was quite the dive in the rabbit hole. CM93 is dated but is nice, in the end a pontoon friend with a USB stick nicely gave me his map.

I tried a russian software to export maps but that didn't really work.

I also ended up buying an iPad mini with a waterproof case and I use Navionics and SavvyNavy. Since I have an iPhone this gives me redundancy and nice screen space.

I need to improve my skills to use offline weather and potentially routing.

I have heard of Squid and QTVLM but did not yet try those.

For navigating during the night seeing AIS traffic is super useful and since the VHF on board was not emitting it was a good opportunity to buy a VHF with AIS reception.

I got a RadioOcean, I should have probably gone the extra mile and got an AIS emitter as well, but preferred spending those 200€ on a solar flexible solar panel. It would have been better to upgrade the solar panel fixed installed but that was real work.

I spent 100€ on a NMEA2Wifi adapter it works nicely to get AIS on Navionics and OpenCPN.

Debugging NMEA traffic, below is a small tool I used to view and debug the nmea traffic on my boat, principally AIS and GPS information.

The tool can be used with python

import socket
import sys

if len(sys.argv) == 3:
ip = sys.argv[1]
port = int(sys.argv[2])
print("Run : python3 <this system IP 192.168.x.x> <server port:2000>")
ip = socket.gethostbyname(socket.gethostname())
port = 2000

# Create a UDP socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# Bind the socket to the port
server_address = (ip, port)
print("Use Ctrl+c to exit")

while True:
print("####### Listening for UDP messages #######")
data, address = s.recvfrom(4096)
print("Received: ", data.decode('utf-8'), "\n")

значит таможенное оформление 4 months, 3 weeks ago

Также вне зависимости от того, осуществляется классическая доставка (один заказчик перевозит лишь “свой”
груз через транспортную компанию) либо же реализуется сборная доставка (когда большое количество заказчиков везут
товар небольшими партиями), таможенное оформление
необходимо для любых типов перевоза груза.

Если вы выбираете надежную
транспортную компанию для осуществления
перевозки груза и вопросы таможенном
оформлении груза вводят вас в замешательство, к выбору компании-перевозчика следует отнестись более внимательно, поскольку
в подавляющем большинстве случаев транспортные компании лишь доставляют груз
из точки A в Б.

Piece of writing writing is also a fun, if you know after that you can write otherwise
it is difficult to write.

Hmm it looks like your website ate my first comment (it was extremely long)
so I guess I'll just sum it up what I had written and say, I'm thoroughly enjoying your blog.
I as well am an aspiring blog blogger but I'm still new to the
whole thing. Do you have any helpful hints for newbie blog writers?
I'd certainly appreciate it.
