The V-8 powerd Tyne boats can do 20 knots. The V-6 powered boats do 17 or so. Max speed of the Shannon is 25 knots. The Shannon's displacement is actually 18 tons, not 15.

The Wikipedia description of the Shannon does not jibe with the RNLI's specifications.

And yes, the Shannon design was done in-house. However, this is a lot different than saying the design was done in-house by the Navy, Coast Guard, etc.

History has proven that governments can't design a proper paper bag. The RNLI, being an all-volunteer organization, has some remarkable people in its ranks-- I've had the priviledge of meeting some of them.

So while I have no idea who was on the RNLI design team for the Shannon-class boat I would not be surprised if it included some of the UK's best naval architects and marine engineers.

And as to efficiency it would boil down to how much added surface area the second keel brings to the table. The props would get cleaner (less disturbed) inflow water and there may be other advantages too.
Far more important, those keels eliminate almost totally the chance of people in the water getting caught in a propeller. This is one of the strong reasons for going to jet drives in the new boats.

Lifeboats have different criteria than a pleasure cruiser, because their operational envelope is completely different. They are designed to capsize and remain operational and complete the intended mission. They run at high-speed in weather conditions that keep pleasure boats in harbour. Sea state has less effect because at high speed dynamic stability is a larger factor.

I've always been leery of people talking about "tripping" and what they imagine waves effects are on a boat. We know very well that any boat can be capsized by a breaking wave with a height equal to 60% of hull length. And some boats will be capsized by a breaking wave with a height equal to only 30% of her length. For a 33' boat that's a 10' wave.

In the PNW I can imagine lots of ugly scenarios with chunks of drift jammed between those keels and a shaft or prop or rudder. No thanks.

The designer is Irish, hence the Shannon name.:

Boat experiencing any sea conditions, or being mechanically forced to roll over... Immediate, natural return to upright is GOOD!

Looked for Marin's picture thread thinking it may be a more appropriate place but couldn't find it. This 26NT isn't far out or strange but it's newness and all white color is stunning IMO. She's on our float and it's hard to walk right by w/o at least slowing a bit.

Nice looking boat. A 26 footer is too small for our uses, but I like the lines of the "original" Nordic Tug. Much nicer than some of the top-heavy looking monsters NT makes these days in my opinion.

Thanks Eric, I like the look of the NT26,lovely proportions.
What is that on the bow? I recently saw a very new Jenneau 42 sailboat with a padding "cushion" around the bow secured with 4 lines, presumably to prevent marking the bow while on a mooring buoy.

It is hard plastic strips (sometimes metal) which prevents the bow from being damaged by the anchor.

Mine does not have these, but does have a damaged bow.

Love those lines of the 26-32. Here, however, is a recent ad for a very nice 26 that uses this shot as the main photo in the ad. Great ideas in canvas are not always complementary to style, no..?

Is that a pop-top camper?

What do people think the right price is for this boat?

Craigslist:

**REDUCED PRICE - 91' EXPEDITION YACHT (SEWARD ALASKA)

**REDUCED PRICE - 91' EXPEDITION YACHT

200000. Good bones. Lots of work to make handle able by 1-2 people and modern comfy. 2 new gensets and what else. This would be instead of something else you could get that was more turn key. Not an expert on steel pilot boats or a broker. 😃

looks like a really cool BIG boat with really little propellers!

18500 gallons of fuel?? yikes!

Looks like it would go anywhere.

You can get a lot more yacht for 800k than this beast. Pilot associations are not known for discounting their surplus boats.
Keep in mind that a full time crew assisted by a shore side maintenance staff maintains these vessels. You have to do the same or pay someone to do it.No more boatyards,its a commercial drydock and associated costs. If you have to dump it for resale, a very small buyers pool.

Not that we're interested in this boat, but Sailor brings up some points well worth considering that most recreational buyers, including us, would not know to consider. Interesting post SOF.
