I don't love roll back entry. I have the down loaded sheet of Dive ops.
What entry of boat would I look for to do giant stride entry and not roll back.
(have back issues that roll back is not the best for me)
Sounds like you looked at the spreadsheet I put together. Didn't include that piece of info, but wrote in my original post what others have already responded with - bigger boats (sometimes described as slower) generally enter with a giant stride and smaller boats (sometimes described as faster) generally enter with a back roll.
Some have used the term "cattle boat" for the bigger boats - mainly with a negative connotation - referring to a larger number of divers that can be on the boat. If it provides what you want, I wouldn't worry about it. Personally, I've enjoyed all of my dives regardless of the size of boat or the number of divers on the boat. There have been many times I've been on a small or large boat and wished for the other for whatever reason - as others have stated, it's a preference and you are going to Coz with lots of dive ops where you can make a choice. I will say that the easiest, for me, and my new favorite entry occurred off of a RHIB - fins on, slip over the side, don your BC, dive, surface, remove BC, take off fins/hand them up, use the ladder to board the boat.
My suggestion is the same as that of a few others - call/email the op and ask the questions you want answered. I would think that many would accommodate your needs.
