Trojan Boat Forum

The main cabin ceiling is leaking. I think that the culprit may be an access cover on the cabin top just forward of the windshield. The access cover seems to be made of a rubber like material that has sagged – holding puddles of water & it has cracks in it. This cover is sealed around its edges. and seems to be there in case the engines need to be pulled. Can this cover be purchased/replaced?

Welcome to the forum Shake.

It's hard to answer your question without knowing which model of Trojan you have & what year it was made - a picture would be great also. Sounds like you might have a tri-cabin since you talk about a hatch to remove the engines located in front of the windshield.

I was able to post a photo on the Trojan Yachts Facebook wall.

It is a tri-cabin

I have seen these where the cores have rotted out. The only way to do it right is to remove it. You'll have to remove the interior headliner enough to expose the hatch. Cut out the bottom glass and core, replace core, re-glass (doesn't have to be fancy...you won't see it). Use the balsa coring material that comes in little squares; it's light and will take on the shape/curvature of the hatch.

It sounds like you are saying that the cover itself is made of a rubber material that is sagging and cracked. The standard cover is molded fiberglass that fits the opening, is curved to match the curvature of the entire top, and is very rigid and strong.

It may be the original but just thoroughly water-soaked and in very bad shape.

If it is missing and someone has replaced it with a substitute of some sort, you will either have make one yourself or get one made. Beacon Marine has a complete set of drawings for each Trojan made and would be a good place to start your search.

If you disconnect the headliner and roll it back you should see the cover and the clamps that hold it in-place.

I'm aboard my tri right now & will try to get some photos of what mine looks like from the outside so you can compare to yours. Mine is all original. I had it open last spring when I replaced the fuel tanks, the refrigerator, the stove and oven, and all the furniture in the salon. It is very heavy and very rigid. I weigh about 235lb and walk on it when I am cleaning & it doesn't move at all.

I took two photos of the top for you to see.

The first one is taken at a little distance so you can see how it matches the curvature of the top.




The second one is closer up



Hope these help.

Thank you Tim – You have been a great help. The photos indicate to me that it is what you said… “It may be the original but just thoroughly water-soaked and in very bad shape”. I will try to post photos later today, but what I see is you top – but soft, sagging, and old. I will look into what the expense will be to have a new one made by Beacon Marine. (I have no knowledge of fiberglass and I need to do something about the leaking.) After removal & replacement I suspect that a sealant is placed at the joint. Is that correct? While I and looking into a replacement I was planning on re-sealing.

Bob or Don at Beacon Marine can probably help with the drawings and may know some sources to get it fabricated from fiberglass.

The top sits in a "U" shaped channel that is formed on the top of the salon and lifts out when the clamps are released. Once clamped back in-place, the entire gap is filled with caulk.

Would like to see the photos when you get them posted.

This is my 1st attempt to post photos – hope that I get it right.



Re: ‘filled with caulk’ – I have “Elastomeric Marine Sealant” by Sudbury. States for use above or below waterline, for use on fiberglass, permanently flexible…
Do you think that will work. I would like to re-caulk now while investigate having a new top made.
Thanks for all of the advice!

I can't see the photos since it wants me to log into FaceBook and I don't do FaceBook.

If you'll email me the photos I will get them posted for you.

mail to k9th@yahoo.com

done Thanks

Here they are.





I see what you mean. Looks like it already has caulk around the outside. I would remove the old before applying any new. Is it leaking in the center area at all?

I have not yet taking down the headliner to see exactly how or where the water is coming in, but the headline gets soaked with a good rain or washing of the cover. The cover is soft, sagging and holds a puddle of water after a rain, so in may be soaking through.
