Sandrett, Backrest, International Signal Flags (Letters N & C) [Separate] Yacht (8.4m) Blueprint

This is a set of three items (①-③) useful for operating/cruising small vessels (including yachts and motorboats).

① Sandレット: Made of cloth and sand, weight = approx. 600g, length x width = approx. 25 x 8cm.
This is a weight for the end of a mooring/docking rope. Made in Japan with high-quality river sand inside the cloth bag. Unlike rubber ones, it doesn't bounce much when it hits the quay and feels soft to the touch, making it easy to handle. Additionally, it has a moderate weight, allowing for easy throwing when connected to the included nylon rope (lightweight, 6mm x 18m).

② International Signal Flags / Letter Flags: Made of cloth, height x width = approx. 30 x 45cm. Two flags.
The single-letter signal flags N and C together mean distress signal and are recommended to be carried on board vessels under 100 gross tons. Made in the UK, these flags are sewn together, giving them strong resistance to sunlight and dew, and they are lightweight, durable, and flutter well in the wind. Furthermore, they are less susceptible to mold and insects, so there are no worries during storage.

③ Backrest (Back Supporter): Made of plastic, weight = approx. 220g, length x width = approx. 34 x 12cm.
This is used by attaching it directly to a lifeline, and its feature is that it can be installed without removing the lifeline. It is a lightweight hard type made in Sweden (with a solid construction, though the finish is a bit rough compared to Japanese products), with particular emphasis on strength and durability.

I purchased these new as spares (from KAZI Sea Plaza, now online shop only), but I never had the opportunity to use them and they have been stored at home for a long time. Therefore, while there are some signs of age-related dirt and minor scratches, they are still generally clean as they are unused. However, please refrain from purchasing if you are sensitive to such details.

Please note that at the time of purchase, I was told that ① was made in Japan and ② was made in the UK, but there are no tags or other proof to support this.

[Separate Offer]
I also have the design drawings (complete set of construction specifications) for the construction of a yacht (8.4m cutter, designed by Akira Yokoyama). If you are interested, please contact me for consultation.

As this is a private sale, I regret that I cannot offer quality assurance or returns.
Please only purchase if you are satisfied with all of the above conditions.
