RE: Aluminum trawler thoughts and opinions?

Ease of maintenance is the key draw for us. The lack of amenities is too, more systems to keep up to date. We don't have a microwave at home...

In our "budget" is a custom steel boat by a local builder, 8 year old Krogem 42's and Nordic Tug 37's. Different boats for sure. The Krogen is the production FG,boat in our size budget as well. A really nice Krogen 39' would be great!

Aluminum trawler thoughts and opinions?

Charles - Not electrolysis or galvanic corrosion...stray current corrosion...my first experience with it was back in 83' when they totalled a week old million dollar sailboat from a loose 12 volt wire...trashed the hull in less than a week.

There are sensors for this...and I would own an aluminum boat in a second...as long as the alloy was right...it had proper care throughout it's life and had one of those current sensors on the hull.

I left my wallet at home today. Actually I do that most all the time here in Alaska. Sometimes I stop to get something and have to go home and get the wallet. Always leave the keys in the car in Thorne Bay though.*

And why does everyone think that adding ballast makes a boat ride better? Just the opposite is commonly the case.

*Ok fair comment I guess Rick, I'm no naval architect for sure, but just on the surface of it, don't you think a 46' boat, which weighs little more than my 34', with such high topsides windage, and rigged for sail might not be a bit tender..not to mention bouncy in a seaway...hypothetically at least..?

I was hoping that there was 20 gallons of diesel in the tanks and no water for its riding high stance. Add 2400lbs of diesel and maybe it sits lower?

*Unless you know the center of gravity, metacentric height and center of buoyancy...it's only a wild guess...even just knowing where* the engine(s)* and*tankage are and the*beam vesus depth*would give a hint but only a hint of how she rides.

And tender...not necessarily bad..tender with a slow roll to a moderate number of degrees may be a more comfortable ride than a stiff snap roll.

RE: Aluminum trawler thoughts and opinions?

As the owner of a 42' Single diesel aluminum trawler, I love them! We are in the process of complete refit, but I think the hull will outlast most of us. As mentioned earlier, no blisters, no rotten decks, no cracked gelcoat, etc. etc. Just keep up with the zincs and electrical and we are good to go. With the lighter hull a single 120 Perkins is more then enough power, and if we wan mods, just break out the welder! Definitely a good choice.*

RE: Aluminum trawler thoughts and opinions?

Tim,

Is your boat a custom build? What kind of boat do you have? I see your bottom has some rocker aft *...I really like to see that. You're boat probably goes 10 knots like most trawlers go 8.

RE: Aluminum trawler thoughts and opinions?

What would cause underwater aluminum hull to turn black? No electrolysis, has been tested for that. Brackish water.
