Hi,

I am planning to replace the acrylics to my hatches. I know my Hanse 400e of 2006 has Lewmar hatches size 60 and obviously Mk 2, but are they low profile or medium profile? Can't find the information anywhere. I am not sure if there is any difference, but the acrylic suppliers seem to ask the profile. Any recommendations from where to purchase?

Regards,
Heikki

Hi, 

I would try Lewmar direct. I am chasing them over the 2G flush hatches fitted to my 2009MY 400 (and  leaking as I hear is typical). www.lewmar.com

The website has an identifier for post 2007 fitment or contact them for earlier.

techsupport@lewmar.com

If anyone has had any recent success with Lewmar over replacing the 2G hatches, I would welcome your insight. From what I can see, pretty much all of them have ingress issues.

Many thanks in advance.

Hi there, I was wondering if anyone had any updates on replacing or fixing these flush hatches.  2 of mine have separated and soon will fall right off.

thanks

I have 2010 400 with lewmar flush hatches. All the flush series hatches on my boat (9 of them) suffered from powder coat adhesion issues and paint finish flaked of them all.

Lewmar/Hanse offered replacement set but my cost to remove old ones and install the new ones. After much backward and forward i forced lewmar to make me a replacement set with anodised aluminium finish rather than powder coated. (Should be anodised from new in my humble opinion). These will now last the lifetime of the boat. 

Note: cabin top has balsa core, Hanse fit hatches with self tapping screws directly into balsa core relying only on Sika to keep the water out. Whilst you have your old hatches off, drill old screw holes out to 12mm and fill with epoxy, when you fit new hatches you will drill and screw into epoxy eliminating the risk of water entry into deck core.

Regards acrylic covers, the flush series hatches have no rim, the rim on normal hatch protects rubber seal and glue from UV damage a fait bit. On the flush series hatch seal and glue are in direct light and therefore subject to degradation much faster. I have had external cloth covers made that cover all of the flush series hatches including side windows (port lights), these take the brunt of UV and get replaced ever 10 years but acrylic lenses stay like new.

When i replaced my hatches i bedded them on non setting butyl rather than Sika or the like, no leaks in the past 5 years. Your cabin top and side flex way more than you think so any setting sealant will be problematic.

Hi,

Does anybody know wether the Lewmar hatch in the photo is Low Profile or Medium Profile? The boat is Hanse 400e #121 manufactured in 2006.

hi,
If you search my site, you’ll find photos and articles on replacing the hatches and windows on my boat. Made all windows myself.

What do you mean with "low profile hatches"?

Hi Gregor,

Thanks for your photos!

This type of Lewmar hatches are either low profile or medium profile. Medium profile is more solid than low profile, for example the acrylic is 2 mm thicker.
