Strongest boat

[JWellington]

So far this boat is the most sea worthy boat we've found. 19 meters, self righting, designed for Beaufort force 12. Aluminum hull. You can also get a fire boat water cannon installed to deter pirates/thieves.

Years ago at work we moved from regular highway trucks to heavy duty all terrain beasts. Access roads, ramps and general thoroughfares immediately deteriorated as customers realised we would now make it through. In many ways it actually became more dangerous and when something did go wrong it went wrong big time.

Enjoy your new vessel but realise sometimes there are places we are just not meant to go.

I remember a big chunk of steel on a marina here about 35 years ago that was recently launched and being fitted out for the worst that the ocean could throw at it
For decades we saw the owner throw buckets of money at it with this big trip to the ice in mind but it never actually went anywhere.

Then he died.

On sale reality was the boat was a heavy weight pig and totally unsuitable for 99% of the world's cruising grounds and conditions.
Couldn't attract a buyer and it ended up being cut up.

During that same time period Australian Multihull designer Robin Chamberlain and Pharmacist Terry Travers set off to the ice in an open bridgedeck 38ft catamaran and went there and back with no real issue.

Take from that what you will.

Sure, but an American equivalent would come with a mount for a M240B. Also
deterring pirates, though perhaps increasing temptation for thieves lol.

Fair enough, but it seems the Canadian coast guard prefers sturdy to flimsier....for Beaufort 12

This would be a lighter hunk of alu, that can follow those sturdy Dashew boats .....anywhere. Resale a non issue.

Guns not allowed most places in the world....water nozzles, yes.

The Chamberlain catamaran from memory was 12mm western red cedar and 440 gram double bias glass with epoxy inside an out.

It has sailed all through the Pacific islands, around Australia and Tasmania and down to Antarctica

Construction seems sturdy enough.

Just sayin

But I think you missed the point of my comment.

Canada's CG and the RCMP have sold their patrol vessels in the past, so
keep your eyes open for any that come on the market.
I was interested in one about 5 years ago that was an aluminum cat with
twin Man V-10's and surface drives.
It was before I was seriously boat shopping, alas.

Probably good too, but this one probably has 12mm or more of alu....I've seen others with 16 km alu hulls. It didn't state hullbthinkness, but designed for Beaufort 12_has to mean a lot.

Providing our Coast Guard with a newer class of ships also helps keep our shipbuilding industry busy.

Magnifique! Definetly not a floating caravan!

Yes, these are built in both Ontario and Quebec.

Quite right, not just a party boat! But one you can take thru the northwest passage, and round the horn with. For intended use for the coast guard , their range is short, but for private use of course that can be extended.

I didn't v miss your point....that even flimsy boats have sailed all over. But for those who lie robust seaworthyness, this has to be one of the best.

 

[long-cours.62]

The stongest

I know


https://www.boatdesign.net/threads/polar-bound.49298/


65t of "pressure" for each 0.836 sq/m !!!

 

[long-cours.62]

also German

"SAR" was for sale last year ( ? may be not sure )German SAR Patrol Boat For Sale




Oops already 3 years ago !!

Yeah, you did miss it.

The point was that you can spend your best years searching for or building "unobtainium" and when you get it are to far gone yourself to use it.

There is no doubt that a Motor Life Boat (which is basically what we're looking at here) are about as stout as they come. The self-righting nature is amazing.

However, these are not normally long range cruisers. These are very high HP (400 - 500HP twins), fast boats that can cruise into the mid 20 mph range, but have a navigable range of only about 200 miles. Even throttling down a high HP engine is not going to get down to the fuel burn to where a Long Range Trawler with high torque, low HP is going to run.

Unless you're choosing to go out in the low lat's during hurricane season, you're going to have fuel issues long range cruising the high latitudes with these boats.

Yes, but boats can be, and often are modified. Look at the German SARs above, they already get 1500 in at 10 knots. If you slow to 5kts.....how many, with the same motors? Over 2000, right? Then if you put in smaller motors, more distance. If you go hybrid, more. These boats can circumnavigate.

 

[JWellington]

Haha, we will do this before we are 80. And we hear of, and see 80 year olds at sea. And these boats are not, ' unobtainable', or science fiction, but actually exist right now. The above examples are available at any time.

 

[rslifkin]

They're available, but not necessarily cheap. And many of them would take some real work before they're practical to cruise in.

In my mind, it's most important to figure out where you want to go. There are a ton of boats that'll take you to 80 - 90% of places with plenty of safety margin (provided you don't ignore the weather and just go whenever you feel like it). It's only the last few percent of places that truly require the most extreme of boats.

Plus, you can always start off with a good boat, go a bunch of places, and then trade up to a more capable boat if you find yourself still wanting to go to the more challenging places.

 

[psneeld]

Ice breaking, ice capable, and adventure vessels are whole different ball games...been there done that.

Thin plastic sailboats have survived rollovers, knockdowns and surf....ice and rocks and bad skippers do them in... bad skippers do them all in.

Pretty sure those Canadian 19m and USCG/RNLS MLBs cost well over $1.2 mil new and will need significantly more to turn into a long range cruiser.

 

[long-cours.62]

ok not "strongest"

ok



by far !!

But just to illustrate what you wrote , a boat could be more economical by only change it use/speed

for example this former patrol boat during the test at sea you can see the different consumption.(with big old fashion engine)

• 5,45 nds -------- 13,40 lt/h -------- 2,46 lt/mille vitesse mini sur un seul moteur
• 7,81 nds -------- 24,24 lt/h -------- 3,10 lt/mille
• 8,00 nds -------- 27,54 lt/h -------- 3,44 lt/mille
• 9,00 nds -------- 35,93 lt/h -------- 3,99 lt/mille
• 10,00 nds -------- 47,90 lt/h -------- 4,79 lt/mille
• 11,00 nds -------- 63,47 lt/h -------- 5,77 lt/mille
• 12,00 nds -------- 83,83 lt/h -------- 6,99 lt/mille
• 12,53 nds -------- 95,80 lt/h -------- 7,65 lt/mille vitesse de carène pour 26,50 m à la flottaison

At "low" speed" like trawler under hull speed the comsumption is similar ( some time better than a trawler).
And the range at low speed could be better than lot of trawler.(with no reserve)

• 7,81 nds environ 4600 milles
• 8,00 nds environ 4137 milles
• 9,00 nds environ 3658 milles
• 10,00 nds environ 3000 milles

Trawleurisation d'une ex vedette rapide !? - Trawler long-cours

 

[Shrew]

I say 'go for it'. Most recreational pilots fly Cessna's and the like. John Travolta flies a Boeing 707. Just because most people don't do it doesn't mean it can't be done. There's a guy anchored in the harbor in a 108 ft steel tug built in 1954. Not an common recreational vessel, but he seems to like it.

Just need increased range. To 2000miles. And that can be done.

We know where, round the horn and Northwest passage, but NOT sit in the ice all winter.

Thanks for corroborating......sturdy boats, that can circumnavigate.

 

[Northern Spy]

Uh huh.

The Bay class boats are just being launched with an average price of $7.5 million CAD each.

The Tahsis boat just showed up last year. It's pretty sweet.

 

[long-cours.62]

In the past year I saw two alloy boat from the canadian governement for sale one monohull and one catamran the resale price was far, far below for this second hand boat .
As in France for former patrol boat ...
For example this one former French custom boat fiberglass two near news C ( under 2000h 3/4 years old, 23.50m lenght sold 40000€ DF 24 Sua Luiga ..., like this one 28.5 m DF 37 Nordet sold also 40000€


Ok ok all fiberglass but just to illustrate the "gap" betwen buying price and resale price just need to wait ...30 years :lol::lol:
