New Lazarette Covers

I started to tackle the installation of the new lazarette covers and discovered a significant amount of core rot in the deck under the port cover. The bedding had failed allowing the core to become saturated around 2/3 of the perimeter. I am digging it all out and will ultimately back fill with thickened epoxy before installing the new lazarette cover. The balsa was so wet that when I drove a screwdriver into it, a stream of water came out! Whether you install new lazarette covers or simply reuse the old ones, it is worth removing the covers and properly dealing with the exposed core in the deck cutout.

Thats weird.... I checked mine when I put my new hatches in...and the wood was like new.... I wonder where the moisture came from??? That is such a high area that unless it was condensation there would not be any way for water to get in there.... I don't know what the answer is though.... but I sure would make sure I had a good answer before I sealed up that edge.... and trapped any water in....(assuming that it is getting in some other way other than the raw edge).....

Has anyone else found moisture there ???

Glad you found it before it caused any major problem.....

I am shipping a batch of hatches out today to those that are still waiting.... they arrived at my house yesterday....snowed last night...gotta go into town to vote today anyhow...
 
OK now...This is REALLY, really the last batch for awhile....last time I said that....six folks said they wanted them.... so I ordered two cases of hatches....(10 sets) so I have 4 sets available..... but that is it...at least until next summer..... Sue and I are getting on the Road on Sunday to Biloxi and so the GREAT Hatch Deal...is going to close for the winter....Honest !!

If you want new hatches....Speak up NOW !! I have now gone through 90 hatches..... hopefully the factory will take notice and install these on the boats they are now building.....

Thanks

It looks to me like the polysulfide caulking under the hatch rim was not too heavily applied and was limited around the screws. It had clearly failed at every screw hole as the screws removed very easily. The boat, new to us, was outside and uncovered 12 months of the year. I suspect that rainwater seeped down the screw holes and to a lesser extent under the rim. In some areas, I had to dig out an inch to get to core that looked OK but for example, on the forward end of the hatch, I had to go back in about 3+ inches. I would say that the average was close to 2 inches. I am likely to tarp the boat and let the core dry out over much of the winter before I put the thickened epoxy in place so that I have as little leftover moisture in place as possible. This is just another example of why one needs to treat a balsa core properly and to keep the moisture out to begin with. BTW, I dropped the new hatch in place to see how it looked. It looks great and will be a real improvement. Thanks again for running the ordering process and shipping the hatches.

Belay that order for 2 covers Joel, they won’t work on my lazerettes.
I have my canvas hold-down straps attached too close to the current covers, so from looking at Roger’s installation have determined they won’t fit without repositioning the strap hold-downs.

Thanks again for your hard work.

I just talked to the manager at the sales office.....where I order the hatches.....he told me that C-Dory is now installing the hatches, but went with a smaller size ....maybe to save money.... I sure would not want a smaller opening....... whatever... after a few complaints, maybe they will go to the size we are using.....

Hi All,

I see that some have installed the hatches with BoatLife and some with 5200 and also with silicone. My new hatches have a label on the inside that say to only use silicone. I would prefer to use a polyurethane or polysulfide. Any one know why there say to use only silicone?

Thanks,
Steve

I removed the lazerette OEM Bomar hatches because of regular leakage from rain, sea, and washdown on the Bomar, and installed this same deck access hatch pictured in the post for "The Hawk is here,'" known to me as manufactured and distributed by Imtra Marine. As I recall, the Bomar require some work to remove, with care given to avoid damage to the gelcoat, and there was some filing to get the correct fit for the new hatches, and some new drilling to match the deckplate pattern of the Imtra hatch. Imtra recommends use of silicone sealant so the plasic is not weakened. Both hatches were replaced in two hours.

Flawless performance over the last 6 months in sea, rain, and washdown - no leakage at all.

Hope this helps.

Looks like it has something to do with the chemical reaction, or lack thereof, of silicone on the plastic.

I installed mine (or more properly said, I had them installed as I don't trust myself cutting and drilling on a new boat...it'll have to get some real nicks and such before I get brave) and they are just great.

Joel,

How about putting me down for two for Sealife? If you can give them to Roger, I can get them from him, or ship 'em. Tell me how much I owe you including tax, shipping, etc. and I'll mail you a check.

Thanks,
 
Hi Mike...... I am in Apalachicola right now.... I do have some in Chester and hopefully will be there around Christmas ... I will bring a set back with me when I return sometime in Jan..... (maybe)..I will put them in your boat....or give em to Roger....

I mentioned earlier on this thread that I had severe water intrusion and rot around the entire edge of the port lazarette hatch when I removed it extending back several inches in some places. I was dreading tackling the starboard lazarette hatch but I did it this morning. Pried it off and the core was perfect and dry as a bone. I routed it out (trusty Dremel tool) and have filled it with thickened epoxy. It does demonstrate that you really need to check everywhere for water penetration into the core. If I had pulled the starboard lazarette first, I never would have known there was a problem.

So, not being a chemist or fiberglass guy, I'm wondering what the consensus is for this. I'm not sure I like the permanentness of the 5200, though can't see any need for removing them at this point, but also know that the silicone won't stand up forever. I am getting ready to do mine and would like to do it right.

Actually getting my new hatch covers on now and came up against the "installing instructions for silicone use" :roll: So some questions come up:
1. Is Boat Life a Silicone based? to comply with manufactures instructions.
2. What are the down sides to using Silicone?
3. Has anybody used either and then wished they had used something different?

I like the new covers, but the factory cut hole is generously sized for them. I found I could only use one existing screw hole. Very little room to move in either direction. Two screw holes had some rusty stain. All seemed dry.

Noticed the factory is using these covers in a smaller size, (according to this thread). Would not like that too much :sad , as we had to shoe-horn the new group 27 batteries :evil: into the ones that were there already.

Thanks again Joel for all your work to make this great :thup improvement.

Hi Everyone..... I am back in the mountains again for the summer....and I have one case of Lazarette hatches remaining... (that's five sets)....

They are $77.98 ($71.10 plus the shipping 6.88 set) Plus....whatever the actual shipping to your address...

If you would like a set, just let me know, send me your shipping address and once you get the hatches....then you can send me the funds....
