I have a H36 with a furling main with partial battens in the sail. Simply, this system will add another 10 years or maybe more to my sailing life.
I've seen more seasoned sailors (old timers) giving up sailing their boats with traditional mains due to the physical and awkward demands of reefing in rough weather, hauling sails up and down, securing them in ties, applying bulky covers at a days end. They may be purists that refuse to go to in mast set ups or it may be the expenses of converting to in mast. Some I know just say, they didn't have any charge left in their body to raise the sail to the next waypoint.
I personally love the traditional main for its performance option, *tradition*, romanticism, and its feel of being really involved out there sailing. I tend to compare my like for the traditional main by comparing it to a true standard transmission on a car versus an automatic that does all the selections....do we not all love the hands on approach?...especially when sailing?
The in mast system versus traditional system and the trade off is relative to the enjoyment of being out on the water sailing...no matter what! I've had two back surgeries that were successful, 99% of the time it's my wife and I that go out, and sad, but, true...I'm getting older too! My reply is not an argument, but more of a consideration to those sailors like myself that wonder just how much more sail time is there ahead. The in mast main is perfect for us and at the end of a day sailing you are more relaxed, with a lot more charge remaining in the body. Once familiar with the operation of an in mast main...it's nothing but smooth sailing! NOTE: Every boat with in mast even identical models have their own special characteristics. This can be due a lot to your own special characteristics and in how you set things. Eventually, through trial and error you will find the *sweet spot*! It doesn't take long!
