Hi all-

Tried searching a few different terms but couldn't find a thread about this. Has anyone replaced their bowmar hatches with Lewmar (Ocean or Medium Profile)? If so, does anyone know the specific models/sizes/config?

I vaguely recall reading something some time ago that one of the lines will drop right in with minimal grinding/filling in tne non-flanged config...

Also - I believe the main salon/head hatches are the Lewmar 10 and the foredeck the Lewmar 60... Would be great to confirm if anyone has done this switch.

Thanks!
- Jeff

Hi Jeff,

I replaced the 2 small Bomars with (size 10, I think) Low Profile Lewmars, which were the last 2 on clearance from Defender. I needed to cut out the deck opening about 3/8 on all sides, but it was all in solid glass - no core. I sanded and painted the exposed deck edge below the frame for a pro installation look.

With compound and a polisher the ugly forward Bomar cleaned up nicely. I did not remove the light from the plastic frame and grid, because I was afraid it might leak after I "fixed" it.

Silicone was used to bed all of the hatches - leak proof the first time.

This was probably one of the easier jobs on my long list this year...

Regards,

Jeff

You can replace them with out cutting the deck. You need the Lemar without a flange. They mount flush to the deck. Not sure if the low-profile comes without a flange. But they are perfect matches with the stock opening.

Thanks Jeff and David! That helps - appreciate the wisdom. Time to do a final measure and place an order.

Thanks!

Jeff -- If you'd be so kind as to let me know what you ordered, and more importantly, if they fit, I would appreciate it.

Good luck,
Brian

I used the Lewmar Ocean 10s without the flat base to replace the old small Bomars. I had to fill the old holes with epoxy and then re-drill new holes for the Lemar's. Not a hard job at all.

Jeff how did this work out for you? Specifically which hatches did you end up ordering and how smooth was the installation?

Regards,
Dominique

I installed the Lewmar Open Ocean hatch without flange on Mithril last summer and it has been great. Easy job. I used 4200 and also had to fill in old holes and redrill.

Was this for the V-berth hatch or the small head/salon hatch? Either way which size did you use. My hatches are done and I want to replace them this winter. Just need to get a handle on which hatches to order

After looking at the different Lewmars this weekend I would like to try the low or medium profiles versions but I'm not sure if they'll fit without modifying the deck. A little more research is required I guess.

It was the V Berth and I used the lewmar ocean 60 without a flange. From prior posts the other hatches would be the 10. I do not know if the lower profile hatches fit as well. I am hoping to replace the two smaller ones next season.
