Steel trawler

SD462 (Diesel Duck 462 Sedan)

Our Diesel Duck 462 Sedan has lots of advantages. The large raised main saloon is more "home" like 

with lots of space, good views through those large windows and great for entertainment and water sports.

The full displacement and flush deck 462-Sedan, using the proven full displacement

Diesel Duck 462 (DD462) hull, watertight compartments and commercial type water tight doors 

and hatches, is our attempt to make one of the most seaworthy sedans available.

We do not advertise this boat for circumnavigation. Nevertheless one of our 462-Sedan's sailed 

from Hong Kong to Hawaii and the owner and crew said it performed just fine. 

The rest of 462-Sedans owners always cruised from USWC to Alaska to enjoy summer seasons.

The sail assisted trawlers were designed with sail rigs, besides providing stabilizing and

fuel economy, provides "get home" capabilities just in case of engine failure.

Remark:

Boat can be arranged for shipping to any major int'l port all over the world if not sail away.

Boat registration with Owner's dedicated reagion/country can be pre-carried out prior to delivery 

from Seahorse Marine yard. Details to be arranged with each dedicated case.

TESTIMONIALS 客户来信

This was our 14^th cruise to Alaska! We have travelled over 50,000 miles and have 8750 engine hours.

And we see more and more Seahorse Marine Diesel Ducks in Alaska each year, it seems.

Here is who we saw this year as we passed by, and some we chatted or visited with: 

Laysan

Shearwater

Luck Dragon (Kwakatu)

Arakatu (David Ellis)

Peking (now with second owners)

About Time (saw, but did not talk to owner), now kept in Wrangell

?   (Mandarin, who is now kept in Ketchikan)    

Umiak, 2^nd owner, met them last year, saw them docked in Puget Sound on AIS as we passed by this year

Thank you for the Seahorse information in separate email.  By the way, in 2019, a very small leak

developed in the gasket of the inspection plate of the starboard fuel tank. 

And I do mean a small, drip……60 seconds……drip  (not drip..drip..drip)   

We had an excellent company we had worked with previously (when we owned our first boat)

come out to take care  of it because we were about to go on a long trip to Australia. 

Once the fuel was out and they opened it up, the two fellows were amazed at the condition

of the tank in a 10 year old boat. 

The tanks were in excellent condition, pristine, like they were brand new.

These guys were very impressed and I just wanted to pass that along.

Thanks for the offer on LED lights etc.  We have had one LED light fail, a few years ago

and we had 2 spares, we left the boatyard with, so we were fine.

Then what we did do was take the lights in the heads and shower out of service and

put those away into spares and replaced them with Dr. LED 6-3/4" Chromed Mars

Dome LED Cabin Light - Dual Level White, 12/24V SKU: 196758 Item ID:

 DLE 8001528 that we obtained from Fisheries Supply here in Seattle. 

The price of the Dr. LED lights has doubled since we did that.

Well, best regards to all, 

Marcia and Kurt
