Dear fellow Hanse 312 owners
The two small Lewmar opening hatches over the chart table and the gally has lost their handles, and I am looking for a spare part replacement of the lid or the whole hatch. However, no Lewmar hatch in their catalogue are matching the deck hole (approx 174x312 mm). Have anyone, an idea what to do and where to order? Thx in advance.
Best regards
Michael

Than you for your reply. I tried the Danish reseller Reese Marin - and they could not help. Also the Hanse webshop seems empty on this item. I have tried to email Hanse Yachts Monika Diedrich - don't know if she still is there. She helped a lot for like 15 years ago with other items. Have anyone tried a direct contact to Lewmar UK?

SVB seem to have parts often used on Hanse. It may be worth checking their website:
Handles for Boat Windows buy now | SVB

If your widow has a lens code on it you can use the Lewmar support page to identify spare parts required: 
Lewmar Hatch & Portlight Identifier
Or drop an email to Lewmar technical support.

Thanks for this input. I actually tried SVB as well - and I did order Lewmar LP Size 20 hatch as I thought this came close but it was 2 cm to wide and long. 

I contacted Hanse Yacht yesterday and they will try to source a product no on the hatch as this a special sized one. Hopefully, it is then possible to order the hatch at Lewmar with this reference.

For anyone interested, I have now got the product id for the opening hatch which is 393129933. I have tried the product identifier from Lewmar but without result. Now I will try to contact Lewmar UK directly to know if the hatch can be supplied.

I finally succeeded to order the custom made Lewmar opening hatches for my Hanse 312 (2005) (similar to 342 and 371). The correct order no/product name is 30162200 LP 246X386 GRY SLV HATCH LEWMAR, and can be ordered at https://shop.chastheboat.co.uk/pages/contact-us.

I can highly recommend Chas Newens Marine, they were very helpful in sourcing parts for my Hanse 400 that I was unable to find elsewhere.
Chas himself was Thames Waterman and a well respected member of the boating community. He sadly died last year.
