Stormjib, clearly you failed to see how I said it can be a problem for some and there are varying levels of experience. The average inexperienced charterer would very likely benefit from a working wind gauge so they can look at the wind speed in the morning and check the reefing chart on the cat they are on and reef as needed. They should also listen to the forecast to see how things may change while sailing too.

And yes, loads can impact any boat, but your link to a racing boat has no relevance here. A typical charter mono is going to heel a lot in most cases if someone doesn't reef when they should. A typical charter cat is more likely to have something break.

So while you may not want or need a wind gauge and I could get by without it (but I do prefer to have working instruments) I think we should be able to agree that there are some people that will benefit from having it. It could be argued that they shouldn't be chartering, but that's a whole other topic..
