Gear Review: The 3D Marine Coach Kit

Make Your Chalk Talks More Interactive

So for our first Gear Review Article we picked the 3D-Printed Coach Kit from 3D Marine and More, a german company we found through instagram, and found really interesting. Often times, coaches are looking for every edge and tool available to bring their kids to the next level and we think this could be helpful for many coaches working at all levels - because kids love interactive sessions with coaches instead of coaches just talking at them.

We had reached out to 3D Marine in early March and a very nice lady by the name of Tarja sent us not only the 3d coach kit but also their Pro Racer Flag Kit, Regatta Elements Kit, Compass and Start Watch. Here's our thoughts and why we think you should think about picking this set up

3D Printed Coach Kit 

The 3D Printed Coach Kit is 3D Marine And More's first offering, which actually came from a request from the coach at the Potsdamer Yacht Club for a 3D-printed opti for some trophies, but the concept was so interesting they developed this magnetic coach kit specifically for Opti coaches. 

Kit Contents

Our first impressions when we received the kit is that the boats are smaller than we thought, but after playing around and testing them they are a really good size. The boats measure in at just under 2 inches (5 cm for you metric types) so they are big enough to be easy to see on a board as well as be small enough to pack into your bag.

The set includes eight (8) boats and 6 marks which is enough to complete a trapezoid course with a gate with a starting line. The boats come in a multitude of colors, which we thought was great for kids especially in green fleet, which can hold their attention a little longer than the typical 4 colors that other magnetic boat sets include.

3D marine also includes a spare set of mast/boom combos because well, things happen and we work with kids. This allows you to work with the boats and talk about sail trim and body position, and as the kit brings 8 boats its enough to talk about large tactical situations and starting line tactics. 

We found two potential pitfalls with the boat kit, one is the fact that the magnets do not come glued into the boats so they may fall out if you don't notice so we recommend that you make sure they are glued into the boat so they do not fall out. Another potential problem is the aforementioned mast/boom pieces which are not fixed into the boats and we see people losing them very easily. 

Opti, Sail and 3d printed marks

Pro Racer Flag Kit

The Pro Racer Flag kit is a really cool addition to the 3D Marine offerings, as it includes most - if not all - the flags you'll need to talk to the kids about racing. It includes the flags you see above and they are all made of the same sturdy plastic that the boats are made out of. The kit also includes a race committee boat, which we found odd to include with the flag set since we thought it would come with the coach kit with marks and boats. 

In any case we see a lot of possibilities to show your sailors the flags and meanings since they come in the correct, true-to-life colors and you don't have to wear out your dry-erase markers drawing flags in different colors!

Regatta Elements Kit and Compass/Start Watch

The Regatta Elements Kit is a straightforward addition, and provides color indexed arrows to denote wind direction and shifts: green for right shifts and red for left shifts. The current indicator has a 3d printed part to denote the current, which we enjoyed but will still have you telling them what it is. We suggest making the arrow itself wavy, that way its even easier to distinguish.

The compass and watch however, is an interesting addition because although there is definitely need for a visual aid for time in a chalk talk, we just are not sure we would pay the extra for the compass and watch when it could just be drawn on the board. But then again, if you don't have a board handy, this would become very useful. The 360 puck we are not sure of what it's intended to be used for, but we tried using it to denote fouls and penalty turns. Worked out pretty well.

Final Thoughts

We took a good look at the kits that 3D Marine And More sent us and found that although we wish the coach set included the arrows, and that the sail pieces were more permanently attached to the boats, we love the idea of incorporating them into our coaching groups and we've already seen kids react positively to them.

We think this set would be best for opti coaches working with green fleet and RWB sailors starting out on the USODA circuit, but any coach can bring some more color and interactivity into their chalk talks with these boats. We also think that if you are considering getting anything from 3D marine, definitely pick up the magnetic flag set. It will make your life easier when in front of the board!

Is This A Chance To Start Fresh? Parents Take Note

The Opti Class is a large enterprise spanning some 150,000 sailors (probably more) worldwide. They all love to sail, and some love to race. Under COVID-19 racing as we know it will not be possible in the near term. That does not mean we can’t race, it means we need to do things differently. There are many really smart people who race sailboats and organize racing and regattas. Plenty of them are in the medical field. There is tremendous brain power at work right now sorting through the issues of how we can continue to facilitate the development of young sailors in a safe way.  The first recommendation is for us to let kids get back to sailing for the fun of it, simply to enjoy sailing for what it is. Just get them out and let them explore their watery world. Sailboat racing, like many other things in life, has been heading in the direction of more and more perfection and complication. We are going to be dialing it back. As we ease into racing it will be with fewer people out

The Post-Opti Life: 29er Sailing And Skiff Culture

 A New Series To Connect Sailors To What's Out There We tried something different with this one as we constantly get questions about what comes after the Opti. Part of what we want to do at Opti TV is to connect the class with the next steps, so naturally we went to take a look at the 29er class from the viewpoint of what kind of sailor wants to compete in 29ers. The 29er is a deceptively simple boat that requires agility and strength, and a mindset of sharing and growth. As a pre-olympic boat it's not for the faint of heart. We went over to the US Sailing Center in Miami to meet up with 2Niner Head Coach Phil Muller for day 1 of racing in the 2nd event of the Skiff Generation Grand Prix, a really great event that he has put together with US Sailing and the 49er class. It was a great day of racing, albeit light and notably it had several of the US Sailing Team members racing on 49ers and the 49erFX. We'll let you read the recap here: SGGP Event 2 Recap because we were more

What Should Be In Your Dock Box/Ditty Bag

 Although the Optimist class is comprised of children, the fact of the matter is that serious racing happens in the Optimist class and that carries with it needs for equipment and replacement parts. Any sailor or coach worth their salt will tell you that you need a ditty bag or tackle box to carry spare parts and tools in order to keep your Opti up or in case of technicals - breakage - out on the race course.  The historical example of a ditty bag, complete with marlinspike So what should you keep in your ditty bag? At the bare minimum, your ditty bag needs to have tools to repair or adjust parts of your boat. A good set of screwdrivers, of medium length, pliers, and a crescent wrench are absolute musts Example contents of a ditty bag. Note the ample variety of tape, tools and spare line Next, you'd want to add a roll of sail tape, the thick kind, to patch up tears or holes that might happen. I cannot stress the importance of dealing with that sooner rather than later, because a sm
