US single bolt allows an extra inch of fw/bw mast track adjustment, fwiw. |

Euro can go to zero extension while the lowest extension with a us cup is 8 or 10 CM, so with a certain setup the us cup will not work. |

If you use the Euro Pin, make sure you check it before each use to make sure it isn't loose (Coming unscrewed). After about four jibes I had one unscrew and my rig separated from the board. I was windsurfing in the Lagoon of a small island and this happened at the mouth of the Lagoon. As the currents were dragging me out to sea I almost ditched my rig and paddled for it, I thought the pin had snapped off. I decided to check one more time and I saw the pin inside the extension, it had just come unscrewed. |

I recently discovered that euro pins are attached via loctite red. Probably a good idea if you are concerned about them coming unscrewed.
As far as sand, if your base and extension are dry when you couple them, I doubt sand will be an issue. I have been euro for years and agree with everything the other euro guys said earlier. |

I'm having a hard time seeing that. We have a whole set of sails with US bases that are set at a max of 1 cm from the cleat at the CSUS Aquatic Center.

Use Euro 98% I have had sand in one that required some extra cleaning otherwise no issue at all. They are easier to detatch for a older fellow. Of note not all euro plns are compatable with other euro systems.
I would not consider changing over... but would replace to when needed _________________ K4 fins

I didn't see anyone mention that the euro pin system allows the lowest setting on the extension to be closer to 0. I recently got a sail that needed to be rigged on a 430cm mast with 2cm of extension. All of my US bases have a min setting of 8cm or more. I found that a Euro system allowed me to set the extension at 2cm and it sounds crazy but it made a big difference when setting my boom height etc.... I use both Euro and US and find that they both have their + and -'s. Euro is faster and easier to attach until sand is involved and the US system does rattle around more. _________________ _____/)_____

OK I believe it's in the difference between SDM and RDM, the skinny extension has to transition to a fatter diameter at the US cup and this keeps one from removing the collar and having the mast sit down on the top of the cup, i.e. there is a funnel shaped bit at the bottom of the extension where the mast cannot slide.
On my Chinook carbon us cup skinny extension the minimum is 10 cm but on a SDM US cup you can remove the collar and the mast can sit right on top of the cup. |
