This is sort of like a really big C-Dory. Well, maybe not in the same league. Still it might be intriguing. The easy of using a 35' boat as a "boater home" and all the trailering is a bit overstated IMO.

If the front berth is a true queen island the boat is going to be too wide for casual trailering like a C-Dory.

It's still in development. It will be interesting to see how the final version turns out. You could almost use a CD16 as a tender for it.

One thing that seems odd is that the displacement of the 35 is stated as 6000 lbs, but the 37 is 48000 lbs. Seems like a huge difference in weight for 2 ft. Yes, I know that 2 ft in length is more than just adding 2 feet to the hull. However, even that does not explain how a 2 ft increase in length results in 8x the displacement.

Leading-edge composite materials seems to be how they are able to build such a lightweight hull.
I filled out the survey to get a design team t-shirts.
Hay, LOA of 35' that's able to make 20 knots with twins 60 horse outboards; all I can say is more power to them.
This could be a game changer.
When and if I'm ever financially able the N37 Great Harbor has been at the top of my list.
The T35 may change that perspective.
 
One other thing to keep in mind with respect to the weight difference, the Great Harbor N and GH hulls are solid fiberglass below the water line, not cored. The 37 and 47 also have close to a 16' beam.
To to be able to pull a 35ft boat with a 1/2 ton truck would be amazing.
 
I saw this on another list server a couple of days ago. They have not completed the first boat yet. There is a lot of speculation in the design specs and performance.

still a number of details and options that will be defined and refined based on customer feedback.

There are pluses and negative to the GH line. I personally would not buy one, based on some of the feedback of the larger inboard boats.

The beam is over 10 feet--so a permit is requited--and may be some restrictions on time of trailering etc. There are similar designs, which are within trailerable beam. (David Gerr NorthEast 34 Trawler: http://www.gerrmarine.com/DR_NORTHWEST_CRUISER.html ) Could be built as outboard variant.

Think of the Trailer length with a 35 foot LOD boat. Add a couple of feet to bring the outboards up to trailering position. then the tongue--probably another 5 feet--so a trailer length of in the neighborhood of 42 feet. Most trailers that size are 5th wheel, or similar to keep the weight over the rear axle of the truck. Initially they said a 1/2 ton pickup--but are still saying full sized SUV as tow vehicle. I would not tow it behind my Yukon XL.

The suspicion is that the dry weight without motors is what they are talking of with the 6000 lbs. Sort of like the 1800 lb C Dory!

Can you make a 35 foot boat, out of exotics, foam or NadiCor, etc and keep the weight at 6000 lbs? Absolutely. BUT it will be very expensive. The interior bulkhead and furniture would also have to use this type of technology.

Another issue to me is the flat bottom. We have a little deadrise aft with the C Dory, but this boat looks to have no deadrise, until you get up well forward., Maybe the boat will not go fast enough to pound, but I suspect that it will.

They are claiming a range of 800 miles with 150 gallons of fuel and cruising speed 8 to 15 knots. The 8 is going to be achievable. The 15--maybe WOT with twin 100's. OK, lets say that you can get the 800 miles--this means an economy of 5.3 miles per gallon. (Actually close to 6 if you were to have the 10% reserve normally required in range calculations).

I took the survey--but don't want the T shirt.

It will be interesting to see the real boat, performance, and photos.
 
There is the Eco-Trawler 33 that is similar in design and specs.

Its dry weight is stated as 7000 lbs. and gets 3 NMPG at 9 knots on about 100hp.

Those boats go for about $220000 new and don't have all the amenities that the TT35 is supposed to include.

They are towed with a conventional hitch on a triple axle trailer. Even at 10% of gross the tongue weight should only be about 700 lbs.

I don't think they've sold very many of the Eco-trawlers.

I was on one of these at a boat show. While they are nice, there is the effect of being in a long narrow space. Getting to the front of the boat is usually out the back and along the side. Like a C-Dory, but it is a much longer way.

Might be good as a canal boat though.

You would be hard pressed to land this boat by opening a side window and grabbing the dock (or flipping a line) like you can do in a CD22 or 25.
 
That is a really, really cool looking cruising boat. I signed up!

Transom between the twin outboards could be a really nice solution to the "outboard motors ruin nice big swim platforms" problem.
 
Ssobol,
Thanks for the link on the ecotrawler 33. I was not aware of that boat. There is an article at"
http://trawlersmidwest.com/pdf/eco-trawler_article.pdf

She is truly a displacement hull--looking at videos of her running, at full speed, she is not lifting much--and putting out a fair wave, for the narrow 8 foot hull. She is aluminum. There is a keel.

She is really a 6 to 8 knot boat. 6 miles per gallon at 6 knots seems like a good compromise. If you get up to the 15.7 knots at 6000 RPM the mileage drops to 1.7 miles per gallon.

The cockpit is self bailing--I like that. It is probably necessary, since this boat looks far wetter than a C Dory--the trial ride, and videos show water over the foredeck at speed.

One of the issues, I see with the Ecotrawler 33, is the lack of room in the main saloon There is no table. The head looks smaller than the C Dory 25. However the boat is nicely outfitted, sprayed in foam, liner etc.

Base Price is $123,000, but outfitted is over $230,000. Lots of great boats in that price range. For example you can pick up a nice used PDQ 34 cat for $189,000--not trailerable at 16 foot beam, but an economical boat which will run at 14 knots. With a huge saloon and deck area. (one boat documented at 3 miles per gallon over almost 5,000 miles and average speed of 11 knots)--but entirely different types of boats.

I suspect the Great Harbor 34, will not perform as well as this boat, speed wise, if the bottom is as flat as it appears, there will be quite a bit of roll, and slap/slam--but only know after we see sea trials, and the real lines of the boat. There was a Great Harbor (Mirage 37) which went East Coast to Hawaii. I had heard that the delivery crew left the boat in Ensenada. I believe that the owner, and some factory folks took the boat across to Hawaii. She was put up for sale shortly there after, and was on the market for some time. The GH 37 is more like a "Florida Bay Cruiser--live aboard--a lot of room in a small package.

One of my friends had written a bad review of the 37, and a law suit was a result.

Anyway, it will be interesting to see what comes with this light weight trailerable boat--if she comes in at specs.
 
Reviving this year-old thread to post this interesting update video----

https://www.youtube.com/watch?v=9Q7oxIb ... e=youtu.be

They are getting 5mpg at 10mph---with one or two 60hp Suzukis--- a speed difficult to efficiently achieve for most boat designs.
The prototype is not what I find attractive, especially in it's bare un-rigged state but the inside drawings show a very livable interior for a shallow-draft outboard powered cruiser.
Too pricey for me but I find the concept interesting.

I think it is an interesting idea. The styling leaves a bit to be desired (IMO). But it could be a fairly good compromise between a boat with real livable space, pretty good efficiency, and portability.

The ride might not be that great in 2 foot chop based on the hull shape.

The boat in the video is clearly a prototype and some allowances must be made. The boat is incomplete and the economy numbers might change when the hull is fitted out and finished. I expect that the weight will go up considerably (for instance, this boat is supposed to carry a household refrigerator).

If I had a $quarter mill lying around I would be seriously interested in this boat. Sigh.....
 
If the Great Harbour 35 can do 25 knts on 120 hp, why can't the C-Dory 25 do the same on part throttle with 150 hp? Why dido I have trouble at 15 knts on smooth water going up the Sacramento River this summer?

Well, it looks like the GH 35 is just a stripped hull with just enough insides to make it run. If you add windows, seats and the other accoutrements cruising boats have, then the top speed would be meaningful.

I know that Journey On gets slower as we add weight. If we're just going to San Diego Bay for a day or two, the boat is faster then if Judy packs it for the summer; it certainly gives less speed (or needs more power.) And of course there's current.

Not a criticism, just a thought from an idle mind.

I remember a firm called Hybrid boats here in Western WA that manufactured an extremely nice looking 25' welded aluminum trailerable trawler. It was quite economical: the power choices were single 60 or 90HP Honda outboards. Well built, with traditional lines. I can't find more than an old Facebook page on the web, so I guess they didn't ultimately make it. I suppose most of us with our busy lives and limited time need to go faster in our typical boating mode.
 
I don't think this boat is intended to go 25 on 120 hp.

The questionnaire is quoted below:

The TT is designed to operate efficiently at speeds from 8 to 20 knots. With standard power (2 X 60 hp outboards), it is expected to cruise at speeds in the 14 knot range. What cruising speeds would you find most desirable? *

This is from the Specifications:

Power: Twin 60 to 115 hp
outboards
Cruising Speed: 8-16 knots

It's also not going to be that light.
When the 150 gals gasoline and say 50 gals water are onboard, the weight goes up by 1300-1400 lbs. Add people and their gear. Total weight could be 9,000-10,000 lbs.
 
First, my disclaimer: I know Ken Fickett, owner of Great Harbour Trawlers and Eric Kraft, Sales Manager quite well and have been consulted from the beginning on the TT35.

We should not confuse the Great Harbour TT (trailerable trawler) with the Great Harbour Trawlers such as the N37, GH37, N47, GH47. Those are full displacement models designed to cruise at 7 knots. Consider that Mirage Manufacturing, which builds these boats also builds fast sportfish boats that feature lightweight, but strong hulls. So building a "fast trawler" is not out of the question for them. (Fickett has also build a number of fast, lightweight sailboats over the years.)

I have spoken to Fickett and others who were onboard during the initial sea trial for the TT35, and they had 8-people onboard along with barrels and buckets of weighted objects to approximate what the final weight would be. Although still lighter than the final production model, they found that the Suzuki 60's topped out at 300 RPM less than spec and that the engines were mounted lower than their ideal height. So it is possible that the performance of the production model will be close to what the initial sea trial showed once the correct props are fitted and the mounts adjusted. All-in-all, this boat should cruise at about 12-15 knots while burning about 4gph. Not bad for a 35-footer.

Fickett thought long and hard about the boat's beam, as he wanted to find the right balance between trailerability and comfortable accommodations. He finally decided to go with 10'4" knowing that some owners would hire a boat transport company to move their boat around the country rather than trailer it themselves. For those comfortable with getting the various permits and with a decent sized truck, trailering it themselves is certainly an option.

Having personally made the switch from a 45-foot diesel downeast boat to a TomCat, I know the advantages of cruising with outboards, and so I think Fickett might have created a real game changer with his 35TT. He's been aboard my TomCat, and we've discussed the development of the TT for the past 3-years. I'm glad he's finally at the stage of building the boat, and I believe he's already had a number of deposits. I can't wait to hop onboard , hopefully to run one of these over to the Abacos. The concept is sound, so let's hope he's successful in the final stages.
 
George, great to hear from an "insider". I think the TT35 is a great design, wish the style was a bit less of a downsized N37 and more of a modern cruiser.

Specs include a 5 degree deadrise on the transom. So not flat but no deep vee. As they say, every boat is a compromise. Seems like a great looper boat to me.
