It contains 11 knot cards with step-by-step instructions, a video course, a boat cleat with suction cups, two ropes and everything you need for the exam.

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be ensured.

Packaging of the knot training set

The knot practice set from Knotenstunde arrived for our test in a typical shipping box, which was easy to open by removing the adhesive strip and arrived undamaged .
The box contained the storage bag wrapped in bubble wrap with the instructions, two ropes and the boat cleat.
Unfortunately, plastic was used to protect the product from dirt . In this case, the product was fully protected and the training set was therefore in perfect condition.
The packaging of the knot practice set is unfortunately not fully recyclable.
The first impression is very good, as neither the product nor the packaging used was damaged.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the package complete and does the manufacturer make it as easy as possible for me to use the product straight away?

*The maximum score is 100 points

After unpacking, the knot practice set with a carrying bag, 11 instructions, two ropes and a boat cleat lay on the floor of the living room. The instructions for the individual knots are very easy to understand. They offer the customer the opportunity to learn the knots in detail.
Unfortunately, the customer is not offered a customer hotline . However, the customer has the option of sending a letter or e-mail to the company using the address provided. This information is printed directly on the outside of the packaging and can be easily viewed by the customer.
Overall, we still consider this to be a good shipping method.

*The maximum score is 100 points

In our practical test, we extensively tested the knot course for the recreational boating license sea + inland and the Lake Constance skipper’s license. With a total of 11 different knots , it offers a comprehensive range to be well prepared for the exam .
We found the included video course, which shows all the knots in detail, particularly practical. This allowed us to memorize the knots not only by reading the instructions, but also by watching the videos. The course is very comprehensive and goes into every detail. This made it easy for us to copy and practise the knots. It should be noted, however, that the cards are unfortunately not waterproof , so you have to make sure you practise in dry places .
The supplied boat cleat with suction cups is very robust and holds well on all smooth surfaces. The ropes supplied are long enough to practise and test the full size knots .
The large bag contains everything you need for the test.
Overall, we are very satisfied with the knot course.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we look at how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also examine consumer ratings and check whether the critical and positive reviews are actually justified.

Rating cut4.5 out of 5.0 stars on Amazon75 points
Total78 points
Weighting: 20%
*The maximum score is 100 points

On the Amazon platform, consumers have given the product an average rating of 4.5 stars. One criticism is that the writing on the cards is small and the suction cup does not stick to all surfaces. Many customers like the included video course, the storage bag and the completeness of the set. In our practical test, we were also able to confirm these points, although we found the writing on the cards large enough to read everything.

Prices of up to €25 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €9. With a price of €15.90, the knot practice set from Knotenstunde is currently in the middle price segment. The price ratio is good for the quality and scope of the product.
