Hi GeoITA,
My words (referred to by petermac33) are simply my personal experiences with booms during the years, involving a lot of other booms than the ones from Maui Sails. I'm really sorry if you feel that "your boom brand" is treated in an unfair way.
No need to go into a lot of details as to the booms from Maui sails, I stick to my words. But especially concerning the MS boom heads, just allow me to say, that it isn't the first time the easily cracking MS boom heads have been brought into daylight - for instance in the (now very silent) Maui Sails forum. And every time the issue has come up, the Maui Sails people (and you, as I remember?) have blamed the users for tightening the head too much.
So just for clarification: When I've taken a new MS boom head into use, I've of course always started to clamp the boom very gently to the mast. When it then slides down, of course it has been clamped a bit more securely to the mast. When it still kept sliding down it has been tightened further ... and so on. And after a pretty short period of time the head has given up and cracked. I've really tried, but I never found the sweet spot where the MS boom head didn't slide down AND it didn't crack. For me, I don't think this sweet spot exists. And believe me, I've tried rubber shims, I've roughened the masts etc.
Obviously, you and others have got more positive impressions from using the (otherwise very strong) Maui Sails carbon booms. I think that's what the "Gear Reviews" section is about, to tell our honest opinions. And better do that without questioning the motives of the contributors.
Lastly, this video implicitly tells that I'm not the only one who has experienced cracking MS boom heads (
www.mauisails.com/2016/tr2016, from approx. 6:15 to 7:25). And by the way, if I've ever tightened a MS boom head as much as Phil McGain does on the video, it was destined to crack!
Best Regards,
Peter
