Congratulations to you both, she looks great. I like the way the outboard motor are mounted wide apart for docking.

Nice shots. GREAT looking boat. The difference between the drawings of the non-FB model, and photos of yours, appears like a different boat.

Will/do you have some blog or social media where we can follow along to learn more, please? I am particularly interested in performance.

Congratulations!
 
Congrats! Glad the build is finally over and now you can enjoy your beautiful boat.
 
Great looking vessel. Must be an impressive sight being trailered as well. Best of cruising success to the entire Mariso Crew!
 
That should be a very handy boat! Congratulations.

Some smart guy once said a boat should either be small enough to put on a trailer in your driveway or large enough to live on. Looks like you have both!
 
Best TT35 ever, thanks to a little help from your friends in Tampa/St. Pete. Too bad the manufacturer couldn't get it right.

Is the Great Loop tour eminent?
 
There should be a law about showing off your new boat while wearing shorts and squinting in the sunshine.. But have fun. :)

Indeed, Don. She is now 100 x better than when we got her a year ago.

We are so glad we decided to just get her repaired and rebuilt up to ABYC standards instead of taking the builder to court. Much less expensive, much less time-consuming, and now we have an awesome boat and many new friends in the marine industry.

Concerning the Loop, we will be doing two short shakedown cruises as soon as our legendary electrician, Charlie Johnson, finishes up the last two projects. As you know, Don, we had planned to start the Loop back in March 2017, shortly after our boat was supposed to be finished. Our old big dogs are now 11 and 13, so we will figure out during shakedown if we think their aging hips can handle such a long trip. If we decide they cannot, we might just trailer her up north to a lake near my mom for the summer.

We also still need to get ADR Power (Andrew - another amazing technician!) back out to help us adjust the Glendinning throttles. They are too sensitive. Fortunately I did several tests in reverse before attempting to dock, so I knew to barely touch the throttles when I backed her in to our slip.

As far as leaks go, we had a few topside leaks when we received the "new" boat from GH. Re-bedding deck hardware (chamfering and utilizing butyl tape) became easy for us after the first few times. Now there are no more leaks.

And as far as blogs go, I don't know if I will start one. After our first cruise I will try to post some numbers here on TF for the gas mileage, etc.

I forgot to mention above :facepalm: the wonderful job done by Monopoli Marine in Tarpon Springs. Pete and his son Peter built the flybridge railings. It was not a simple job because of the pitch of the upper deck, and yet just like all of our other local craftsmen they were an absolute joy to work with.

Cheers,
Pea
 
Congratulations, love the concept and now the boat. Enjoy :dance:
 
Congratulations!!!! Now starts the slow, inevitable corrosion and degradation of every single part.

;)
 
We're both so happy for you, to finally have what you dreamed of and thought you were getting. It looks beautiful and I'm sure you'll find it most enjoyable. You have far more patience than I do and it did you well.
 
Congrats on getting to the light at the end of the tunnel. Now you've got something you can be proud of and enjoy.

If you'd be comfortable with it, I'd be curious to know what work done by the various contractors. What needed to be modified to create the boat you're happy with?

Okay, and I will try to be concise!


What needed to be modified. Well, we had six main issues. I will break this up into six separate posts to describe each one.


Our marine surveyor spent two days surveying the boat before we made our final payment. During our surveyor's first day, both he and Dan noted that the latest hull under construction, either hull #5 or #6, had a cockpit floor that was 3 inches higher than our boat's. This was a hint that something was off.


Two days later during our lake trial of the boat, we observed that the cockpit sole and fold-down gate on the stern were slightly below the water line, meaning the cockpit was permanently awash, even when underway. (See photos 1-2 below from the lake trial.)


The fold-down gate had 1/3-inch openings on all three sides and when the outboards were in reverse, water poured into the cockpit from all three sides.


After some counterproductive discussions, we brought the boat home from Gainesville to St. Petersburg. We still loved her unique design and shallow draft, but we were exhausted and frustrated after waiting two long years for the build to be finished.


We decided that rather than hassle further with the extremely slow & quixotic builder that we would get her fixed up ourselves.


We consulted with a naval architect and took the boat to American Boat Works (ABW), the marvelous fiberglass shop that I referenced in my first post. ABW cut out the existing cockpit floor, built a new cockpit floor, and fiberglassed it in 3 inches higher than the original floor, as we had noted in hull #5 or 6. (See photos 3-8 below from the ABW shop.)


Paul and Kevin of ABW then built us the new closed stern with a swim platform instead of the original fold-down gate. They installed two nifty brass scuppers in the cockpit deck so rainwater can drain. (See photos 9-10 below, which are BEFORE and AFTER photos of the stern.)


These new scuppers work quite well. I did not take a photo of the scuppers prior to installation; I wish I had because they work beautifully.


Incidentally, I have just learned from another new TT35 owner that GH has now decided to eliminate the fold-down gate on future TT35’s and instead build a closed stern with swim platform very similar to ours. We think this is sensible because, in our opinion, the original fold-down gate design with the cockpit sole raised 3 inches was still susceptible to water intrusion with the outboards in reverse gear.


Up next when I have an hour or so to find more photos, will be the issues with the gas tanks…

Yeah that tailgate was a silly idea. Nice changes.
 
Just looking at the picture on GH's opening page for the TT35 here: https://www.greatharbourtrawlers.com/tt35.html, it looks like the boat rides too low in the water aft. The outboard in that pic looks like it is almost underwater. Further down that page, a rendering shows the outboard where it should be, but not the real world pic above.

Raising the floor 3" is a fix but I am afraid it is a kludge. GH needs to totally redesign the boat to bring its attitude back level. That would solve the water coming in from the aft gate.

Pea and Dan,
Congratulations. I hope Marisol ends up worth the wait and expense, taking you to some wonderful cruising grounds.
Safe travels
Henry and Debbie

Some models in Beneteau Swift Trawler family has an opening gate that opens the transom to the swim platform so that the "Transom opens to extend the cockpit space connecting it with the swim platform, creating a real terrace over the sea." They seemed to have made this feature work ok.
 
Repairs Part Two of Six

GAS TANK ISSUES from original build


Thanks for following along. I am having fun going through all my photos to create these posts! And re-living the excitement we felt as our boat came together this past year.


If you click on each photo below, you will see my photo labels that correspond to the following descriptions for each photo.


1. Our surveyor snapped this photo, taken inside the bilge, of the metal gas tanks sitting in bilge water. At this time, the boat was sitting on its trailer at the builder’s facility, prior to the lake trial. Metal tanks sitting in water is a pretty big no-no, for obvious reasons.

In addition, the original cockpit sole was installed on top of the tanks, which our surveyor noted could potentially lead to stress cracks in the tanks ("decks can flex").


2. This photo is for perspective. Here is the original fold-down tailgate in the open position. Note the ginger ale can in the lower left just inside the cockpit.


3. A close-up from the cockpit: Above the ginger ale can you can see that the gas tank VENTS were installed INSIDE the cockpit.


4. American Boat Works (ABW) removed the two gas tanks in order to build supports that would raise each of the tanks 2.5 inches above the bilge floor. Since they were also raising the cockpit sole 3 inches to solve the water intrusion issue (see my previous post), this would give us a half inch clearance between the tops of the tanks and the bottom of the sole. Three problems solved!
ABW also strongly recommended that they paint the tanks with an epoxy primer which should double the life of the tanks. Here are the tanks after painting.


5. This is the Pettit Epoxy Primer that ABW used to paint the aluminum gas tanks.


6. Here is the new support structure inside the bilge for the gas tanks, made of very thick starboard and topped with rubber strips. In addition, ABW fiberglassed in a 3-inch high core along the top of the original stringer in order to support the new higher cockpit deck.


7. Just a photo of Mariso in the shop, with the yellow lift behind her that they used to remove & reinstall the gas tanks (this photo brings back the smell of awl-grip in the morning!).


8. Gas tanks re-installed.


9. Gas tank VENTS re-installed on the OUTSIDE of the cockpit.


10. New cockpit sole after glassing & painting and before the non-slip coating was applied.


Again, if you click on the photos below you can see the labels for each photo. And, I have to reiterate what a pleasure it was working with Kevin and Paul, and their shop manager Tony, at American Boat Works. They are all such wonderful, conscientious gentlemen. We were very fortunate to have found them.


The next installment will cover the electrical issues that we had repaired.


Cheers,
Pea

I appreciate your willingness to relay the story for us. I also admire your ability to see all the positives, and not have become bitter about it.
 
I'm surprised that GH hung the outboards on brackets, rather than extend hull back to the motors. It might have given them the extra buoyancy they needed. Not all that hard to do now, extra waterline length and extra buoyancy. It'd be a fun project.
Thanks for the updates. A cool boat.

Your extension approach requires careful thought on the part of the designer. It would appear Cutwater did a hull extension - oops.

A look at the big Scouts, Intrepids, etc with triples, quads and fives show some interesting stern attachment designs.
 
Look at my avatar on the left for a boat with a well integrated stern bustle/outboard mounting bracket. It adds both water line length and bouyancy aft. This seems to be exactly what the TT35 needs but not sure how it would work with twins.
