Only bad point of the design is the I/o with the dreaded maintenance headache .
Expensive per foot. Nice boat for cops! Not too bad if sailing solo with lots of cash and big charge cards. Not my cup o' tea.
BTW: Refreshing honesty from reviewer regarding accommodations and other items. However, his feeling that water conditions were on the rough (i.e. choppy) side simply does not pan out. I've seen hot tubs with more turbulence... when "adult" fun time was in progress! - LOL

I think their claim to low noise is probably much more legitimate than you think as a first thought. Those engines are probably small. Smaller engines make less noise. Excluding chainsaws and dirt bikes of course. And often only one engine will be running. So the engine has a small footprint and/or smaller. What makes more noise on your boat, the main or the gen? Double the size of the engine and you get much more noise. And I forgot to mention that being FD the mains will be smaller in the first place.

I use the TF app exclusively on my iPhone and am having no issue. The standard admin response to app wonkiness issues(technical term lol) is to delete the app and reload it. That has worked for me on the two occasions the app started acting wonky over the last several years.

That's honestly about it really as app developers are seldom if ever part of the normal staff at a website.

I've taken the liberty of reporting your post(best way to contact the admin at any forum) so someone from the Site Team should be contacting you via private message soon.

2017 Trondheim Trawler Power Boat For Sale - www.yachtworld.com

I am behind in this thread but I like this concept. The boat in some ways have the same appearance of a GH37. The interior layout is basically the same as my boat but with more beam. If I could afford it, and had the time for extended cruising from Olympia to Alaska, I would definitely look at something like this.

An interesting Trawler / Cat (former fishing boat) conversion out of Canada:



Full details here:

2004 Ocean Voyager Expedition Catamaran Power Boat For Sale - www.yachtworld.com

Rogue is a former university ocean mapping vessel and is a latest conversion by The Ocean Voyager who have successfully delivered the long range expedition vessels PINK SHRIMP, CHAGOS, and ACHARNE. Her catamaran form offers features seldom found on mono-hull expeditionary vessels. She is stable, fast, and efficient and acts as a comfortable multi-purpose offshore platform. She can traverse 7,000 nautical miles of open ocean without refueling. She has a large crane and extended deck that allow her to carry and deploy a 25' SAFE Boat AND up to a 5 ton submarine. She has commercial scanning sonar and a suite of electronics that are unrivaled in a 90' vessel. Her back deck provides a large outside living and working area. She is as efficient, self-contained, and green as can be with a 2500 watt solar system coupled to a large battery bank, LED lighting, 1600 gallon watermaker, waste treatment, 54 kw of electrical generating capability, excellent HVAC and air handling, and many duplicate systems for maximum reliability and comfort.

Rogue is a true global cruiser. Her twin 400 hp Cummins diesels give her an easy 12 knot cruise speed and up to 14 knots of speed when needed. She carries 3,800 gallons of water and 12,000 gallons of fuel. She is built entirely with high strength marine grade 5083 alloy and 6061-T6 framing for maximum stiffness and 3 foot transverse frame spacing and 1 foot longitudinal spacing. The plating is 5/16” thick under the waterline, ¼” for hull and decks and 3/16” for the superstructure. Rogue is an excellent high lattitudes catamaran and, while not ice classed, was was originally built for the waters around Newfoundland and Labrador where ice is common into July. Her comfort systems make her equally at home in the tropics.

Possible we're talking about different technologies. I envisioned something like diesel-electric locomotives, or submarines (watch Das Boot), or the 80,000 ton ro-ro on which I had the good fortune to sail.

If their concept is to cruise on battery for a hundred miles or so and then run an overnight charge, like my electric Smartcar, I suppose thety make a valid claim.

But, the massive fuel capacity and twin generators suggest that case 1 above is what they propose.

I don't know...the deep vee steel hull would slice & dice waves, and the two "tunnels" for the props where the stern flattens out would presumably slow down snap rolls. That, and you could easily run at whatever speed is most comfortable. Every boat is a compromise, and this one could get you into all manner of wild exposed coastlines or make fast sprints across open water

Haven't looked at the price however...

Unusual looking Dutch steel cruiser from 1974: GILLISSEN KOTTER 1100 motor yacht for sale | De Valk Yacht broker
The layout is some kind of „special”, but I like the (to my eyes) really pleasing exterior.

I could talk the admiral into that. Wish it didn't have the DD671, or the over 5' draft, or the nearly 70' length. Never mind. Lol.

Looking at that Paravane setup, I thought a center mast was needed to distribute the loads generated? Maybe I misunderstand.
