Default Mako T-Top and snow...

Anybody see this over on CM? I mean, it just doesn't make sense...




Not an original Mako T-top, but in the third pic, looks like the tubes were cut, not broken from weight...

With a cover holding a few feet of wet snow and the leverage of the length of that top it doesn't seem out of the question to me. They should get it fixed and next time prop up the back with a piece of lumber or something. Winter sucks !

It was sheered apart from an unsupported 4 ft. overhang with 2.5 ft. of wet snow on it.



Not the best design. If snow can collapse football stadiums, well...

What desn't make sense? What are you implying?

There was additional weight from the canvas cover holding 2.5' of snow and hanging off the back of the t-top as well. Are you a structural engineer? Can you help me redesign a new one?

If you look closely that my picture that you reposted you'll see the signs of fatigue of an aluminum pipe when it is bent like that. Look how the pipe tapers right near where it split.

If you have any other questions feel free to contact me and ask instead of hiding in another forum.

Sorry pal, I'm not implying anything. I just thought it seemed odd the way the tubes seemed to "break" so cleanly...

You don't need to get defensive about it...

also, I may add here. On any welding job 1 inch from the weld is where ist's going to break. The weld is always stronger and the heat from the weld makes the metal more brittle.

If you got a lot snow and a little wind, it would start that top moving around with all that weight off the back of the stands. Turn it in to your insurance and next year, just put a couple of 2X4s under the aft end of the top and you probably won't have that happen again. Then again, if you put the 2X4s under it, it probably won't snow that much again as long as you have the boat, kinda like buying a snowblower after the last snowstorm of your life.

The real problem may have been the type of cover used. Most likely that cover began to sag and collect snow (& weight) aft of the T-Top, which ended up putting even more stress than just the snow load on the back of the T-Top. Of course, that's assuming that cover originally went up over the T-Top. If it did not, then please disregard what I just posted. Even with properly supported shrink wrap, this year we went out and attempted to rake the snow off as much of the T-Top & hard top cabin boats as possible. Not an easy job, but better than calling a customer up and telling them their boat got damaged.

I agree completely. I've mentioned it a few times in other posts. The canvas cover sloped from the back of the t-top to the transom with little support beside the t-top. The cover ripped right at the seam that ran across the t-top leaving the weight to be all supported by the back. We had about 3' of snow accumulation the day before and it rained that evening. Probably 10-15 lbs per square foot. Over the top and the cover pulling down on it, it was only a matter of time.

Seabob implied I cut the pipes, that was very clear to me and unappreciated . Nothing like having some jackwagon take your misfortune and try to turn it around on you. I could give a shit what he thinks. Everyone has an opinion, especially on the internet where you can hide behind your computer.

You seem pretty tough too, behind the keyboard and everything. Just to recap, Seabob, a respected and extremely helpful and knowledgeable member of this site, said "in the third pic, looks like the tubes were cut, not broken from weight.." He never said you cut them or anything of the sort. You are now calling him names, which, for the record, makes it appear as though you do, in fact, give a shit.

He put "break" in quotations. To me that means he thinks they were not broken. Maybe I have it all wrong.

Being a "respected and extremely helpful and knowledgeable member of this site" doesn't impress me. How is accusing me of cutting the pipes helpful?

Done with this thread. If anyone in the Boston area wants to come over and look at the t-top in person just shoot me an email. I'd be happy to meet you and show you the boat.

When I saw his post, my interpretation was that he was sharing something that was a bit of "wow, look at this". Which is a pretty common practice on internet forums. And then he was questioning whether the boat was vandalized or something. It never occurred to me that he was accusing the owner. I'm sure he wasn't. I think the owner is a bit paranoid!

There was a thread a while back with a hard top that was sheared off while transporting the boat down the interstate on a flat bed trailer. All the breaks on the legs were so clean it looked like someone sawed them off.

^^^ x2

My thought went right to the thread that HH is referring. In that case, a professional transporter "claimed" the wind destroyed the guy's T-top and after shearing off, the top was lost along the highway.

But upon visual inspectioin of this boat, it appeared that the bases were cut with a sawzall.

Whenever there's movement or flex in the pipework On the pipework theres usually barely visible lines radiating around the radius of the tubing an inch or so from the weld. It looks like the anodizing is cracking but it's actually metal fatigue. I have had to have a few spots repaired on mine where it cracked all the way around. Luckily mine was supported by other pipework so it didn't look so catastrophic. We've seen the before now post the after pictures of your new pipework when it's done. It's about 60 degrees here now twelve hours ago it was 6 degrees. I can watch the snow disappearing. Winter sucks! Oh, and SeaBob didn't say you cut your own top, but his repost of your picture may help someone else to avoid learning the lesson you just did. "I'm just sayin". Good luck to you sir.

Seabob's original post would have been less offensive to the owner of the boat if Bob hadn't used the phase "it just doesn't make sense". This type of statement implies that something "devil-ish" was taking place .... even if not Bob's intent.

I'm not getting into the "who cut/didn't cut what" aspect of this thread but that is a beautiful old Mako that had its' prior home near me. Always loved that boat and hope it all works out for you.Nice to see the "Acre Shaker" again. Wonder if Charles has seen these pics?

Suggestion: Next time, go out and brush the snow off the cover or top before something bad happens. That's what I did when I lived in MD.
