First, I would like to say that Yellowfin meets all US Coast Guard Regulations. We are inspected every year and have passed every year. The discussion has been quite interesting and informative.
I would like to say that in my 20 plus years of boat manufacturing I have seen zinc primer tanks, tar coated tanks and bare aluminum tanks all corrode within the general life span of the tank. The majority are from poor installation. Tanks being placed where water can get to them. The world of coatings has allowed tank manufacturers to make the tanks out of lighter gauge metal which costs less and is lighter for the boat manufacturer.
We at Yellowfin chose to engineer our boats where are tanks are placed in sealed off compartments as well as we build them out of heavier gauge aluminum than what is standard for the industry.
Bly and canarianfisher mentioned several things about tanks and installation. Bly mentioned this is old school, well it is and it works and we have 100 percent confidence in our build process. canarianfisher mentioned the tank company with installation pics on how to properly install fuel tanks and that foam is against the rules.. I read their site, the thing i found interesting was they tell you how they think it should be installed to eliminate stress and corrosion to there tanks yet they only offer a 1 year warranty for there tanks. If it was so great why would they not offer a 10yr or 20 yr warranty?
Please refer to US CG Reg 183.512. In short you are required to foam in all non ferrous metallic tanks. only ferrous tanks are installed without foam. your site failed to distinguish the regulations.
Also you can refer to USCG 183.516 this in short also explains the density and pounds per square inch that is required for foaming. 2 lb is required. Yellowfin uses double (4lb).
Also refer to 183.552 this in short tells you how to install and foam in your fuel tanks.
i believe in short you guys may have been a little mis-informed.
Boat manufacturers are required to build to US CG regs, but there is a group ABYC that is made up of ex boat builders, surveyors, engineers etc. that write regulations to improve upon the USCG regs. These regulations are followed by all nmma members. There are many regulations that are improved over the USCG regs and yellowfin has adapted these regulations into their build process even though we are not required to by the USCG.
Yellowfin continues to improve the build processes of their boats and will continue to build safe, fast and durable boats for years of use.
If anyone would like to discuss our processes i am available anytime.

Thank you wylie. This should put it to rest. Here in the bahamas we foam in all of our tanks. Once sealed properly they last a long time.

Thanks for weighing in Wylie. Your support is unmatched by any manufacturer that I am aware of.
Well I'm glad Wylie showed up finally, since there has been such an interpretation of the law, and everyone depending on others posts here is the reg. I found.
This has been a topic that has been occupying space in my mind for a while, I guess knowing about crevace corrosion and having an older boat...I always check the concrete for fuel when I go visit my mistress.
I'm just ready to see some blood on that deck! I'd still like to see a profile of a high back chair, cigar in hand, feet propped up, and a glass of neat Scotch in hand in your graphic!
Detour thanks for sharing, I personally am glad this debate happened, I think it got everyone thinking...

This has been going on for years - always the same occurrence:
1. someone innocently writes a YF thread and slowly it starts to rot with a buy back, some possible production mistake that YF makes, whatever...
2. Wylie comes on on with a single, well thought out, cogent post and runs the table.
3. The crows scatter and it starts all over again in a few months...

Glad to see you check in, W...
It's always amusing when that happens. You've gotta tip you hat to Wylie for coming on here and facing his critics. Detour, can't wait to see some more pics of the build.
I'd like to comment on the fuel filter placement. No matter what the regs say, the reality is that I have seen a lot more rusty filter cans leaking (the steel portion of the Racors) than I have seen leaking plastic fuel bowls. If you honestly expect to shrug off an event where something generates enough heat to melt the bowls, you better start thinking in terms of Kevlar fuel lines too. The access to the filters and changing them regularly is more important to me than the bowl material. I want to know when there is water in there and I don't want to have to drain fuel while in the bilge to find out. So, I hereby confess my sin and admit I use plastic bowls on my Racors. So, if I have a choice, I'd rather have them easy to change and with plastic bowls than have them tucked away with cast zinc bowls.
But I can't go without posing a question to Wylie: I see a lot of things in the construction that I like, but you still don't seem to use bolted flanges on the through hulls. I sure thought that was an ABYC requirement?

well now that the YF stance is documented, this post will be around for awhile for anyone who plans to look for it later....this could be a double edged sword.
It really does amaze me that wylie takes the time to address all issues on boards like this. How many times have you seen reggie (or any other owner) come on a message board to address questions other people have. And from what I've seen he stands behind his product 110%.
And before anyone jumps to any conclusions I'm not part of the yellowfin mafia or whatever it is that some people refer to the loyal owners as. But the amount of service available from the factory and wylie himself sure puts the boats near the top of my "maybe one day" short list.
Thanks wylie for the explanation.I strive to make the mouse trap better.

I just got home from the IBEX trip I in no way meant to say your way was not stronger considdering the size of the tanks? I have done quite a few retank jobs and I have to say for a tank with that many gallons and that width and length I would be hard pressed for a better way then you do it? The only way I could even think about not foaming that much tank would be to devide it into 2 or even 3 tanks and not foam it in. But that is your decision and since your No1 in centerconsoles now! you must be doing a lot of things right with out me? I was asking in the early thread for my own interest and tried in the beginning to be nice til I was even attacked with PMs for posting a question about YFs fuel tank? You have a great following? I never said Old school doesnt have its place? I have always questioned surveyors and others who tell me to do a boat their way when the old way worked for years especialy with a minor tweak or improvement! Thanks again for the reply wylie For my own interest in the next tank install I do which is in a couple weeks

Just my $.02.
strategic marketing. there's alot of potential buyers on here researching new boats and educating themselves, and there's alot of owners on here passionate about their brand. that's the beauty of small, family owned/ non bureaucratic businesses. Accessibility.
It does not matter what coating you put on there! Foam is an insulation product also! You will create condensation between tank and foam no matter what coating? Just like a glass of cold beer on your wooden coffee table and what it does to the finish! That is why coast guard, marine manufacturers and surveyors organizations will NOT approve a new boat with aluminum tanks foamed in! Yes YF does a great job on almost all points of the boat! But this fuel tank issue is beyond most sound thinking? I think you are way off on the tank issue?
Bly Iam not a boat builder but I know insulation and Polyisocyanurate. The sample you made with the cold beer is correct but the cold beer was not insulated. Now tell me if the beer was insulated condensation would not happen. Think big pipelines in Georgia 12" diameter with Liquid Gas inside with an interior temperature of -200 deg and the ambient temperature is 80 deg. with the correct insulation there is no condensation. same goes for the gas tank and I will tell you again not all foam are equal. I blend Poly Isocyanurate with solid carbons that has a 99.9986% of closed cell that is been used in the military for the last 18 years and also in NASA. So if you are having problems with boats that have foam in place tanks, you better check what foam they used.

I have a problem with people who take pieces of reality and blend them into what realy goes on! I have had a little experience in the fields you are talking about except NASA! No NASA in my past. The way that tank in the picture is insulated and is a text book case of causing condensation! If you know anything real world about insulation on metalic surface any break in insulation is going to cause even more condensation in that particular opening in the non insulated area! Its a fact. so then the condensation will migrate into and out of the insulated and non insulated area! Fact. Now if you want to bet a cold beer on what I said? its going to cost you a Guiness. I* am not a professional insulator but have worked side by side real world installing,hanging and supporting industrial piping so that the insulator could do his job properly!
So true.
