I'll bite since I have owned a 34R now for 15 years with runners and checkstays. They are a PITA. So is a Baby Stay and that's why you won't find them on modern designs. Baby Stays went out of vogue in the 80's with most designers except C&C who kept them longer than anyone else. To be honest, I bought my boat because it had runners and checkstays and I wanted to learn all I could about making a sailboat go fast. I don't regret it.
Runners and Checkstays make a difference but I wouldn't add them to an existing design. They complicate the mast with so many anchor points and the deck too, requiring another set of winches or heavy duty purchases. Research has shown me that the forces on the runner block and deck anchor point are close to the breaking strength of the backstay. This requires large expensive blocks and beefy anchor points on deck w heavy backing plates to spread the loads properly. Harken has some great spreadsheets on this but if memory serves, my "end of boom" mainsheet load is around 600# max. I have a 5:1 course with a 20:1 fine tune. The halyards are 1500# max. The genoa sheet is about the same1500 to 2000#. The #3 jib sheet in 40 knots of wind is 3000# plus. While the runner is closer to 10000#. BTW, the highest load for running gear for a typical sloop is the #3 jib sheet in high winds. The highest load for a sailboat with a bowsprit will be the bobstay, which is many times higher than the backstay. It's all physics. > On November 1, 2017 at 3:34 PM jacob fuerst via CnC-List > <[email protected]> wrote: > > Furthering the baby stay thread, has anyone considered replacing the baby > stay with check stays?
