Re: [Electric Boats] Re: Test sail

 

 
Arby:
Usually sailors are not so lucky as Pitt and his crew. Though quick action probably increased their odds of saving the mast.  Usually the mast goes over the side and it becomes critical to cut it away because it could put a hole in the hull. So having some type of way to cut through stays is more critical than a come along. Though a come along could help in winching the mast back on board which is not an easy task. Some sailors in England simulated a mast failure you can see the link here:
 A few boat designs like mine have an unstayed mast  which is one less thing to worry about. But, the mast is a much heavier piece of metal. As Eric mentioned some are changing to high tech lines instead of stainless steel for the mast stays:
 It's relatively new but, may result in less surprises than the suddenness of metal failures.

Just curious, does anyone carry a cable come-along for such occasions? It probably wouldn't hold up in a good blow, but at least the mast would still have some support. Purely a novice question.  

Be Well,

Sorry you had to turn back Pitt, I suppose if it had to happen it's better 60 miles out than 600! Did you figure out yet why it broke?

I don't know that there is enough power even in my bank to move my boat into that kind of sea for long but there were times that nudging the throttle Fwd to give me control of the boat in those seas was reassuring, as for the numbers here goes. Distance off shore 60NM motoring for about 3 hrs at low speed enough to move me at 2.5-3kts over a 2-3 ft rolling swell without wind from the GG bridge to where we found wind. We sailed the next 14 hrs hitting between 5 - 7.8 kts the entire time we needed the motors 3 or 4 times for boat control during sail changes and reefing of sails, keeping course into the seas with the motors during these evolutions makes it more comfortable.

Avoiding the Farallon islands in the middle of the night was done with power assistance, we had no stbd backstay for the main and had to keep tension off the mast on that side. We used power to get through the early morning doldrums outside the Gate and had plenty of power when arriving at the dock. Still 52v in the tank.
