Here is what our customers have to say:

SP Marine were incredible. I had a port side tank leak on my 5 year old 40 Sabre SE (which is a story unto itself). SP Marine drove to my boat yard and rebuilt port tank (I had them do starboard too) onsite and in the boat. Their work was flawless and I now have two tanks that are better than when factory/new. And each tank now has a USCG approved inspection/clean out plate I can use to clean tanks every couple of years. I just took boat south to Charleston. Zero issues with tanks. I’m thrilled with SP Marine’s work.

Dear Darren,

I want to express my deepest appreciation for your service.  As a fellow professional, academic physician, former medical school and dean and professor at Johns Hopkins I want to congratulate you on your professionalism. Your boat side manner was quietly competent and reassuring.

I wish some of our trainees and medical students had your gift. The trip was uneventful and everything worked fine. Please count me as one of your references. I look forward to seeing you at the Boat show in Annapolis Audrey and I thank you.

Hi Diane,

I can't say enough good things about SP marine. I used SP for the installation of my Tide Slides and then to clean 3 fuel taks and install access ports for future cleanings. Darren always shows up on time and answers my calls when I need him. Competitive pricing and excellent service, you can't ask for anything more.

Thank you for the wonderful job you did fixing our diesel fuel tanks this week. 

We have seen many contractors over the years working on boats as well as at our home, but you and your mechanics are by far the most professional, systematic, always working in unison team we have witnessed.  You made sure to treat our boat like it was yours, taking caution not to get anything soiled and seeing to every detail.  We are very impressed with the way you handled all expected and unexpected issues, and the way you kept us informed along the way.  We also appreciate your environmentally friendly approach.

Your charges were fair and we feel we truly got our money's worth. 

Thank you and your team again for your hard work, we give you a Five Star Rating!

Ahoy Darren,

Our rebuilt fuel tank is fantastic. No more fuel smell in the boat or oily bilge.

Your crew was professional right from the start and I was very impressed with their work ethic and skills over the 3 days of working on our tank. I feel like the repair is better than new since you not only fixed the problem but also made sure it wouldn't happen again.

Thanks so much for the great job on our boat. Coming in under your estimate was icing on the cake.

I highly recommend your work to other customers.

We've been at this boating game for over 45 years - from a 36 foot Chris Craft to an 84 foot Burger.
We have had every conceivable maintenance or repair issue face us over that time. 

Rarely do we find craftsmen who deliver what they promise. You are one of the rare exceptions. You arrived when you said you would, you protected our boat properly, you accomplished your tasks on time and within budget and you did it all with good humor and obvious expertise.

As a retired CEO of a 5000 employee high tech company with a fair knowledge of mechanical skills, I am a pretty harsh judge of the trades that service my vessel.

You guys are winners. Thanks for a job well done. Feel free to use me as a reference.

To Whom It May Concern,

I was very pleased with SP Marine Services.  From the first time we spoke , I was given specific information regarding the services that  would be needed to fix the leaking fuel tank on my 455 Motor Yacht.  All details were clearly written out as well as to all the expenses that would occur to fix the problem on my boat.

Three men came to work on my boat and completed the job in a quick and efficient manner.  They were pleasant to talk to, informative as to the job they were doing and made sure that the boat was kept clean with all their equipment around.

I would highly recommend them to anyone needing their services.

I discovered a leak in my 250 gallon aluminum fuel tank on my 44 foot motor yacht and searched for a company to repair or replace my tank that was professional, efficient and fair.  Through a marine engineer, we located SP Marine after a thorough search.

Before settling on SP Marine Services, we dealt with other companies and all of their proposals were both more time consuming, disruptive and expensive.  SP repaired my tank at my dock in a short amount of time and at less cost than the alternatives.

They were thoroughly professional.  They arrived at my dock with all of the materials and tools necessary and were completely familiar with what needed to be done and how to do it.

They were thoroughly efficient.  Rather than months on dry dock as with other alternatives, they finished the job in about a week.  Actually, I had them repair my other 250 gallon tank and that was accomplished in another week.

They were completely fair.  Their final bill was less than the estimate and they accounted accurately for all their time and materials.  Actually, their cost was about 1/4th of the cheapest alternative. 

In short, they did a very good job in a short amount of time at a fair price.  I heartily recommend SP Marine!

Darren, your crew did an outstanding job on our 2005, 45 Cruisers. When you opened the port tank and found the corrosion you were able to accommodate opening the starboard tank as well without having to reschedule. We greatly appreciate the extra care you took in protecting our boat while working on it. I don't recall anyone going to that extreme.

When fuel started to seep from the starboard tank on our 53 Krogen Express, I kinda got that sinking feeling. Had big boats for over 20 years. Along the way, a number of boating friends have had fuel tank leaks and not many ended well. Doing my homework on fuel tank repairs I came across SP Marine Services. At first I was a bit skeptical, I’ve tried to avoid snake oil. But the more I learned the better their repair sounded.

After numerous conversations with Darren we set a date to repair the Black Swan. Hurricane Irma had other plans and we had to delay a few weeks, but Darren arrived with first class equipment. I can’t tell you how many comments I have had on how professionally they conducted themselves, even after they had left. I might add this was after Irma, 95 degree humid days and these guys are welding inside a fuel tank.

Turns out the tank that wasn’t leaking was in worse condition than the one that was, so ended up doing both. One of my concerns was that the tanks would have a “repaired “ look, and hurt the value of the BS. This is not the case. Darren trimmed out the inspection covers in the soundproofing. (He has pictures in his photos), and is proud enough of his work to put his companies sticker on it.

By the way, it doesn’t leak!

I thought my summer of boating was over when I discovered a leak in my 450 gallon tank. Of course it was buried under my cockpit sole and impossible to remove without tearing the boat apart. I tried to get estimates from all major yards in Rhode Island, but only one yard would even consider it and it would be the end of the season before they could do anything!

Then I discovered SP Marine who specializes in on site tank repair.

Everyone in my yacht club said it wasn't possible! But they were on my boat in 2 weeks, cut open the back of the tank, cleaned it out and removed baffles, welded a 1/4" liner inside, reingineered the baffles and fuel line pickups, pressure tested, and had me running 6 days later, all without touching the cockpit structure. Saved my summer and left me with a much better tank! Great crew, everything spotlessly cleaned, couldn't be happier! Thanks SP!!

I spent months researching options for solving a leak in a fuel tank on my 43-year old Grand Banks trawler, with no one willing to undertake repairs in lieu of replacement.  Luckily, I kept searching and found SP Marine Services.  Darren quickly called me directly and engaged in a long and detailed conversation aimed at exploring all of my options before we settled on a repair commonly used in bigger ships.  I was immediately impressed with the scope and depth of his knowledge about the advantages and disadvantages of the various options.  It gave me confidence that his repair plan could be carried out successfully.  After excellent coordination of travel and estimated costs with the professional staff of SP Marine Services, I made the decision to conduct the work.  From that point on, Darren and team made it effortless for me.  They arrived on time, introduced themselves to my marina management and executed the repair plan as described; providing periodic photographic progress reports.  In the end, I confidently refilled the tank and voyaged the very same day.  Months later I am kicking myself for not choosing Darren's plan earlier.  If I have issues with my other tank I won't hesitate to contract SP Marine Services again to solve my problems quickly and effectively.  Thanks for working with me to give me the right repair options!
