    Posted: 17 June 2023 at 16:00
Is the gas strut attached to the swim platform actually supposed to do something? It lets the full weight of the platform drop without helpful resistance and does nothing to help raising the platform. Tried turning the whole cylinder but no effect. Also searched manuals, etc. Can you clue me in? (i'm a newish owner). Didn't want to mess with it or try lubricants without experienced advice though did try turning the whole cylinder to no avail. Temporarily rigged 3:1 line pulley system. Thanks,
Steve

Hi, yes the strut takes the majority of the weight, such that you can close the platform with a gentle pull on the restraining line or open it with a gentle push. It sounds like the gas has escaped from yours. Ours went a few years ago and I got a ridiculous quote of around 350$. I have replaced it with a piece of rope led to the rear winch. 
Not as practical but at least I don’t feel like I was robbed!
Good luck

I have the same "problem" and i also talked to two other Hanse 348 owners and they say the same. It's not a "gentle pull on the restraining line or open it with a gentle push". 

Maybe we all have faulty struts or its to weak.

It's possible to replace these failed original gas struts with aftermarket gas struts, at a fraction of the cost that Hanse charges. In the US, McMaster-Carr has a wide selection.

All of the aftermarket tension gas struts I have found have been in black nitride finish rather than 316 stainless.  Is that what you purchased?  Has it lasted in a sea water environment?

I had two replaced under warranty during the first year.  The top ball bracket was repositioned for the second replacement and then served well for 6 years.  Unfortunately I didn't notice that the top socket fitting was becoming unscrewed from the strut, and the strut detached itself a few weeks ago and went 'plop' into the ocean.  But for some thread lock it would be still providing good service!  ;-))  Word of warning.

Yes the black strut seems to be good so far. Has outlasted the stainless one supplied by the factory.

Brand new 348. Terrible design. Struts do nothing to help you pull up the platform. You need to be a weightlifter to get it back closed with just the line. No way my wife could even attempt this.

Hi, very strange they got it so wrong on the 345 and 348. On the 415 I would estimate that the strut took 95% of the weight. 
All the best

I use laser dinghy main sheet rig with swivel and cam lock. Works great. My piston crapped out after one year.
