If you think back to what you have read or seen about the sinking of the Titanic in 1912, there have been many many improvements to the safety since then - so many that it has been a very long time since a liner or cruise ship sank on the transatlantic crossing, and lifesaving is vastly improved.
Now there is radar so that the ship can see far into the distance, they have GPS so they know exactly where they are, and they have a radio beacon which broadcasts exactly where they at all times, so other ships and aircraft know where they are too.
Radio is now voice instead of Morse Code, and takes place on many frequencies - and the ships have satellite phones too so that they just have to make a phone call if they need help.
The ships these days travel with motorized lifeboats designed to take all the people on the ship plus some, they are self-righting, and have rations for a lot of people for a long time. They also carry lots of rafts, and there are always enough lifejackets. As you will remember from your cruising days the ship will have a drill soon after sailing when all this is explained to you.
The advantage that modern ships have is that they can be told the weather and the weather forecast several days ahead and can alter course to avoid the worst storms. The Captains are used to navigating around the worst weather and are competent at it.
I hope that you can get sufficient help to rise past your hurdles and visit the Netherlands. It is a beautiful place and I like it very much - the people are so nice.
Good luck on your journey...
