(Side note, what type of epoxy do I coat my bottom with before I add my bottom paint? again another possible video
Sumner used and recommends the Seahawk 2 part epoxy and I agree. It comes in a 2 gallon kit which is enough for a mac and goes on much thicker with less coats being needed than some of the competitors.
This question is quite simple. How many m models lost the mast due to basic design limits? Ie, not hitting something, hardware failure Ect. I was going to add a backstay but then decided that the attachment behind the forestay tang was not easy to do and would rub on the sails. Runners may put more strain on the mast. Plus they are a pita when single handing. I'm just going to sail the boat and if the mast comes down I'll be able to go NYAAAA SEE THE SAILING ANARCHY GUYS WERE RIGHT!!!!
I doubt it will.

Robin Lee Graham broke the mast on his Cal 24 TWICE (Carl Lapworth 24) and that is a VERY STOUT BOAT with major backstays. He sailed 24oo miles with a jury rigged square sail. I can find dismastings of all kinds of boats on You Tube - there are HUNDREDS of them and they all have backstays.
If you sail long enough in wild enough stuff, you will lose a mast but HEY! IT'S A MAC! A sailing Anarchy guy can't fire up the motor and turn his boat into a power boat and be in the harbor in time for dinner like we can even with a busted mast.
It does not matter because the mast on the MAC is not gonna bust - the boat is just too damn light!! There isn't enough 'THERE' there to break the mast. You need some serious counter weight like a 1750 lb keel under there to create some REAL leverage on the mast to break it. Only way your gonna break it is to hit something.
Now if he wants a backstay then so be it & with an inner or outer forestay for a cutter or sloop rig like me why not , remember I did add a 3rd set of masthead shrouds & a second set of spreaders
lets start with the masthead swivel brkt
I,ll have to find the mods then post the pics from photob
Gez Guy,s lighten up the guy is just asking for advise & help not criticism !
Not criticising just pointing out the error in the OPs belief that installing a backstay on an unmodified rig will somehow help keep the mast up when he is pounding in heavy seas under motor. I think it would be irresponsible to let him incorrectly believe this is a good thing when it achieves none of his intended goals.
There are plenty of circumstances where a backstay is a good idea, this is just not one of them.

BOAT, I have to agree with you here. The mast isn't that tall and isn't that heavy. Normal usage just isn't gonna break it. If it were that weak, we'd be hearing of these things coming down. Plenty of guys have pushed these boats hard. Some with 110+ outboards and pounded waves and the mast stood tall. I really don't see a need to shore up the mast. It's fine.

I disagree a slightly snug backstay will keep the forestay from whipping under power in heavy seas even in 2 ft chop so it does help the rig from taking a pounding & as I have one on my & have seen the diff it makes I feel I,m opinion is more assertive , but I agree that with out a second forestay or even using the jib halyard as a second back-up its pretty much not worth the while with out each complementing the other

Okay, sorry - I am a troll so it comes natural.
I have run boat really hard under power into the waves and I never noticed a lot of work going on at the top of the mast - am I looking at the wrong place? Where is it you guys see all this mooovement? Maybe he should just unhook the boom from the topping lift and tie it to one of the safety lines - it could be that his topping lift is pulling on the top of the mast. Am I missing it? Does your mast's move a lot?

how bigs ur motor !!! how fast u go !!, Yes with a strong enough topping lift & mainsheet on the boom or rigid vang as I have also u can stiffen up or bend the mast top to tighten up the forestay for powering or spinnaker , but for multiple head sails u,ll want to do my mods , remember my backstay is on a swivel on top of my masthead & mounted on a traveler on top of my aft arch high outa the way controlled from the cockpit helm on either side & center aft so she pulls straight back on the mast no matter what angle the mast is @ center, S/B , Port , what ever angle in between
Number of documented cases of mast loss, anyone?
Ps I mean, gee I inspected everything, no fish hooks, no dubious terminals, damaged tangs, dented or damaged masts. It just came down because I was sailing or motoring hard.
Having studied this rig a bit, any stronger-fying I'm going to do will be larger dia. Uppers and lowers, or dyneema, and more robust spreader tubes followed by stronger chainplates and a bit more glass under them. Four bolts each.
All of that I have a feeling is just for peace of mind. I have no intention of redoing the rig. I have plenty of wind. I max out the heel easily with stock sails. Even off the wind , once I learned to trust the rig, it was fine. Seven, eight knots down wind plus a bad accidental jibe that tore the bolt rope off the clew area of the sail. No problems.
The rig can take more pounding then I can, found out one windy day. It was so windy that once out of my shelter I regretted not uncovering the sails since if the motor had quit I would not have been able to because it was so rough. I spend the whole four hour trip worry about it. Meanwhile even doing five knots was slamming the hull and drenching everything on deck. Any less reduced my ability to steer.
This was a miserable little screwup that would have guaranteed any female companions on the yacht would have been getting a hotel that night lol. Fortunately it was just me and the dogs.
Keep the side wires properly tight, but if you still want to add a backstay I would also go ahead and convert the rig into a masthead system. The uppers lowers head and backstay all going to the mast head. That will simplify things in the long run.

But you no-longer have an un-modified fractional B&R rig, you have a full height cutter rig so you have to compare apples with apples not apples and oranges.
The mast is designed to mainly take compression loads putting only a backstay on an unmodified B&R fraction rig will actually induce unsupported extra bending forces at the head which can cause the mast to fail at the upper sidestay attachment point. If the forestay is so loose it is bouncing around under power adjust the uppers to increase tension. If you cannot get the rig tensioned enough because of trailering then you will need runners not a backstay.
As I said there are plenty of circumstances where a backstay is a good idea, this is just not one of them.

Exactly.. plus a halyard for a full height spinnaker
guys guys, no worries!!! I wont do what it was that I was seeking advice for. Man I would hate to ask for directions. You guy might tell me where you think I should go instead of where I was asking to go. Geezzzzzz! Answers are hard to come by if they are not popular here!!!
