19 7/16 X 19 7/16 Bomar 100 replacement options
 
Mrs. Rain Dog here :)

Was wondering if anyone has replaced their 19 7/16 X 19 7/16 bomar series 100 hatches with another brand or even replaced with a fiberglass hatch. I'm having a hard time paying $1000 for a hatch, especially when we need two.

I dont think our present hatches would survive a rebuild, due to the flange that holds the rider arms, I think that is what they are called. The flange has a lot of corrosion at the ss attachment. The hinges look good.

Can't find any with the same cut out measurements(dagnabbit).

Thanks,
Erika

Mrs. Rain Dog,
I feel your pain. Last year, we had a similar problem and I looked all over the place for a replacement that would even come close to fitting, precisely because I didn't want to spend the $$ on new Bomars.

I removed our forward Bomar and bought a new Lewmar (I think it was the Lewmar Ocean 19 1/8 x 19 1/8) from Defender. I knew I needed to do some woodwork for the inside gap (the frame doesn't extend down far enough to meet the headliner), but when I placed the new hatch in the cutout, the flange around the base of the Lewmar did not cover any of the existing screw holes on deck. I would have either had to do some fiberglass work or add some sort of aluminum or wood base (like a washer for a bolt). I'm not good enough with fiberglass to make it look good, and I was concerned with doubling my chance of deck leaks (deck to base seam and base to hatch seam). In the end, I sent the Lewmar back, had the Bomar stripped and anodized (much cheaper than paint and more durable on aluminum, I'm told), and then fixed my cracked support flange with some JB Weld. The anodizing color matched almost perfectly and I have had no issues with the JB Weld fix.

If I had to do it again and couldn't refinish my existing hatch, I would bite the bullet and get the new Bomar. While the Lewmar would work, it requires semi-extensive boat modification and is not as heavy duty as the Bomar. The Bowmar is much more substantial and can be made water tight, whereas the Lewmar frame is much thinner and flexes easily.

Hope that helps,
Brian

Mrs. Rain Dog here

Thanks for the feedback. That is a good idea to repair the flange, it is not a critical part of the hatch. The rest of the hatch is very good, but will know more when we sand blast it.
Thanks for responding,
Erika

My problems are not so bad as yours. All I have done is put stainless helicoils in all (or almost all) of the corroded bolt holes for the props and dab on some new paint. I think I have now done all four bolt holes in each of the two large hatches (saloon and vee berth) and in the smaller hatch (head). I've delt with plastic to aluminum joint leaks with windshield leak stuff in a tube from Advance and replaced the rubber gaskets on all three hatches.

After your note I'll pay better attention to the bubbles under the paint. The devil may be lurking there.

Mrs. Rain Dog again:

Thanks Irish Eyes. I've gotta ask, was your hatch in the head a factory install? What size is it? Also a bomar?


Thanks,
Erika

Our two Vetus dorade vents are in the saloon - port and starboard 10 or 12" aft of the bulkhead. The head has a small Bomar opening hatch with an inside spigot of about 10x10". Our boat has a number of other deviations from the brochure boats. I think all were factory installed.

In regards to the hatch in the head-When we purchased NiftyNickers the head had a Vetus dorade and a small opening porthole.The head felt claustraphobic and airless.I removed the dorade and installed a Lewmar 10x10 hatch in its place.An amazing difference.Air and light,great!The dorade was then installed in the salon opposite the existing dorade providing more air in the salon.My wife's favorite improvement.

Wow, thanks! That is what I'm thinking to do. Did you have any surprises when you went to cut out the area.
Thanks

Mrs.RD
The installation of the hatch in the head was surprisingly easy.The deck at that point is very thick,I suppose to support the mast,and requires a good strong saw and several blades.Once the hole is cut you want to seal all the exposed edges with epoxy.Then only the interior trim is needed,I made my own rather than pay the Lewmar price for a trim ring.The improvement in light and air is remarkable.
Good luck,
