Looking to make slipway work a hassle-free experience while out on the water?
Boating enthusiast and instructor Jon Mendez shares his comprehensive guide on how to successfully launch your boat from a trailer, taking away the stress associated with this task.
His guide covers all of the essential steps you need to take in order to ensure that your boat is safely launched and ready for your next adventure.
(more…)This video looks back on the year 2022. It’s about advanced courses to improve navigation in heavy seas from 3 to 5 Beaufort in the Raz de Sein, France.
“OLM Perfectionnement Mer Formée” translates into the “OLM Advanced Training in Formed Sea”.
OLM stands for “Office de la Mer et des Littoraux,” which is a French organization that provides training for boaters who want to improve their skills and knowledge in navigating through rough waters, particularly in waves and choppy conditions.
In this way the trainee learns how to pass big waves. I’ve posted more videos for you to enjoy like here, here and here.
This training is designed for experienced boaters who already have a basic understanding of boating techniques and safety practices while minimising the risks of accidents and injuries.
It makes it relevant for those who navigate in coastal or offshore waters, where the sea conditions can be unpredictable and challenging.
If you listen carefully you can grab some tips and advice. It is in French though and the author did not active subtitles.

As a naval architect, the computational fluid dynamics (CFD) is an essential and vital tool for analysing the hydrodynamic performance of boat hulls. Prior to finalising the hull design to build.
By simulating the flow of water around the hull using numerical methods and algorithms, CFD allows them to predict the resistance, drag, and lift of the boat.
Using CFD simulations, they can optimise the hull shape for speed, efficiency, and stability by testing various design iterations without the need for physical prototypes.
This helps them to reduce the time and cost of the design process while still ensuring optimal performance.
In the simulation process, naval architects typically divide the fluid domain into small cells and solve the Navier-Stokes equations for each cell to calculate the fluid properties such as velocity and pressure.
Specialists, here is the math explained.
For boat hulls, this involves analyzing the water flow around the hull and the space between the hull and the water surface.
By analysing the results of the CFD simulations, they can make informed decisions about factors such as hull shape, size, and materials to achieve the desired performance characteristics.
They can also use CFD simulations to analyse the effects of different environmental factors, such as waves, currents, and wind, on the boat’s performance.
You now understand, those that don’t use these equations based simulation for building RIB hulls have no clue what they’re doing.
It’s important to note that while CFD simulations are a powerful tool, they should not be used in isolation.
Physical testing and validation are still essential to ensure the accuracy and reliability of the results.
So now I also shared in this article why decent RIBs are expensive (read that article here).

It is a pity that not all text spoken videos have captions also known as subtitles. But …
If they do, you can activate the captions in your own language. Here is a brief instruction on how to translate YouTube video captions.
1. Click on the “Settings” gear icon on the bottom right-hand corner of the YouTube video player.
2. Click on “Subtitles/CC” to activate the video captions see the available captions for the video.
3. Click on “Subtitles/CC” and then “Auto-translate”. In this example I previously chose English.
Clicking on it makes you choose your language form a list (use the scrollbar to look for your language).
Click on the desired language.
That’s it! You can now read the captions in your own language. The translation is as good as YouTube gets it.
Give it a try on this Gemini Marine interview with Gerhard Neethling (CEO and owner).
Many of us have probably been in a situation where the wind picked up and the sea was agitated; after all, you had checked the weather and sea conditions beforehand. There are a lot of good apps for that, by the way.
This video by “OLM Perfectionnement Mer Formée” shows a training session for advanced boat handling techniques in challenging seas.
The session took place in the Raz de Sein area of Brittany, France, and features a RIBCRAFT RIB (Rigid Inflatable Boat) with a single outboard.
he training includes techniques such as passage through waves and jumping over them, with the instructor demonstrating and providing guidance.
You should definitely watch this video as well.
