Rigging Terminology Question

I like to use the proper terminoloogy when asking a question about rigging. I don't know what to call it, so I guess I have 2 questions. What is the name for the attachment point on top of the wheel house where the line form the boom is secured? Is it a cleat, eye bolt or some other cool nauticle term?
The other question I have is about this force this attachment has to withstand. Its a vague question I know, but in general terms, is this a highly stressed point? It on a 50 foot ketch. The boats I have been on have a triple block and tackle there so I would think it may have a large load on it at times.

Thanks in advance

Re: Rigging terminology Question

Without seeing it, or a picture, I would guess that you are refering to the mainsheet's lower block. I do not know if there is a strictly nautical term for it other than a "tack". Unless it is a part of a "traveller", in which case it would be a "traveler car". And yes, there are substaintial loads on it, but the reason for a three part tackel, is so that you can make adjustments while it is under those loads.

Re: Rigging Terminology Question

To get an idea of the loads on the traveler car you can put in your numbers at this site: Mainsheet Load Calculator.

Re: Rigging Terminology Question

Could be a padeye if it is an inverted U shaped fitting made of steel or stainless or bronze. A shackle goes to it to attach your block and tackle for the mainsheet tackle system.
kind regards,
