A headboard car including a stanless headboard toggle with a ø14 mm clevis pin and split ring to attach the headboard. Three 80 mm MDS cars in aluminium. 

Dimensioned for a righting moment at 30° heel of maximum 550 kNm on a masthead rigged monohull yacht and 450 kNm on a fractional rig.

The MDS full-batten concept  -  Full support in all directions

As the name implies, Seldén’s MDS (Multi-Directional Support) cars are supported in all directions, making sail handling simpler.

A full batten always creates a side load on the cars, particularly when you release the halyard for taking a reef. Each MDS car has side-load absorbing wheels that run against the guiding flanges in the luff groove. The interaction between the mast section and the MDS car deals with longitudinal loads, as well as side loads. This is the essence of the MDS concept. Since the cars need no external track, there is also less weight aloft.

The MDS cars are easy to keep clean and are easy to install or remove from the luff groove. 

The MDS system is a suitable complement to the Seldén Single Line Reef boom. With such a combination on board, you have a simple and easily manoeuvred system for handling the mainsail in all weathers.

CHEAPLY CONSTRUCTED SWEATBAND
Size: One Size, Color: Lime, Size: One Size, Color: Lime
The sweatband on the inside of the visor only goes up half way and is not sewn in on the top to secure it in place so it exposes the interfacing which is thin. On the other visors the sweatband goes all the way up and is sewn in. The sweatband material in the other visors is much cushier than this one. Lastly, the sweatband material makes my forehead itch. Other than the construction and materials used in the sweatband, the visor is well made and the color is as pictured.

A good buy
Size: One Size, Color: Power Pink
First, love the color. It's very comfortable. I was concerned cuz I have a small head but very adjustable and it fits. It's breathable my head didn't get so hot like it normally does. I think I'll be ordering another in another color

Perfect Visor
Size: One Size, Color: (001) Black / Black / Reflective
I bought this thinking I wouldn’t like it. I was so wrong. This is lightweight and the perfect fit. What a great value. It’s so comfortable on your head and the vent on it was a great idea. Adjusts easily and just a great buy.

A great sport visor
Size: One Size, Color: (100) White / White / Reflective
My head is small so a lot of visors don’t fit because of the Velcro. This is perfect and the ability to wet it for coolness is great. Love it for tennis.

Great for running

Hat fits well and worked great for my marathon. The Velcro doesn’t pull on my hair.
