I can use whatever. It’s just that I have more experience with epoxy. The problem I’ve always had with polyester is the narrow time window.

Do you think it’s doable with epoxy? I’m more comfortable working with this material. Also, what cloth combinations would you recommend?

The reason for the downsizing is that the original installation was too close to the waterline and cavitating like crazy.

It easier to get to it from the outside. Do you think I can use epoxy? Also, what kind of cloth? The lower half of the hole is about half an inch thick, the rest is about a quarter.

The new tunnel is made out of fiberglass. They recommend using isophthalic resin to bond it to the hull but I would rather use epoxy if possible. Sadly I don’t know what cloths were used.

Hi all, We had to cut an old bow thruster tunnel out and want to install a size smaller tunnel. What would be the right way to fill the roughly 2 inches gap all around the new tunnel? The hull is solid fiberglass.

Those are Simrad EVO2, 12 and 16 inch. They're fine. I'm not big on touchscreens but it's impossible to find anything else this days. They are unusable in bad weather. If you get them it pays to invest in a full remote control. In my experience Furuno is the best. If you can afford it, buy it...

I just finished building my console. The box I'm building right now is basically a cover to cover all my wiring on the Bimini top, radar cable, overhead lights their wiring, various antenna cables and so on. I may have a glove box built into it and maybe my sound system head, spare VHF radio...

You got it. If you have any questions let me know. I'm not a boiler expert but in my job as a marine electrician worked around them enough to have a basic idea how they work.

You got me here. I forgot about this set up.) You don't see this kind of installation very often. What they have here is they are using two economizers, one on the main and one on the ships generators. Because generators run 24/7 but their exhaust is not enough they use their exhaust to...

Yes I red this and it confused me. I've never seen EGE and oil fired boiler run simultaneously,

Oil fired boilers, we call them auxiliary boilers, are only used in port when the mains are stopped, or at very slow speed, when exhaust heat is negligible, at least in my experience. All EGEs have an automatic switch that fires oil fired boilers when exhaust heat drops below a certain temp. Why...

I think I found the answer! I think the way this ship was designed is to use two engines, the ones with the EGEs as primary engines to be run every time the ship was underway. The other two were auxiliary, to be used while cruising or full speed. By adding EGEs on more engines it gave them more...

EGE is basically a water boiler mounted on the exhaust pipe. Hot gases coming from an engine pass around the water tubes in the EGE and produce steam. Steam produced this way is used on diesel ships as virtually a free power source to heat heavy fuel, to reduce its viscosity so it can flow...

This is what I've in mind

The box will be about 4' above the console so if I get the gelcoat color close it will be very hard to tell.

You're welcome. I wonder why they kept adding EGSs? I can see two, but four?

The reason why I'm thinking of taking the mold route is that the outside will be finished. I did my lower console the way you suggested, plywood with fiberglass on the outside, but then I had to take it to a paint shop to have it painted. I don't have a spray gun or a garage to spray it in...

Hi, I been following this forum for a while. Got a lot of valuable hints while building a console for my boat. I in the design process of building an overhead electronics box. What I have in mind is basically a square box. I'm thinking of just going with a female mold made out of ether a...

Not sure about that CG vessel. On modern commercial vessels that stack area, also called fiddley, does contain engine room exhaust and intake fans but most of the space is taken by EGE: exhaust gas economizer.
