Had I not had a full keel I would have lost the prop,as it turned out it was sitting in the apperture formed by the keel and the rudder joining,this is one more reason to have the "correct " type of boat for offshore work,had it been a fin or some other type of hull design other than a full keel I would have lost the prop , now al I have got to do is dive back in ,insert a cotter pin and I am off again..lesson learned?"Dont take a moped to a drag race"

Wow long keel , slow boats loose their props , who'd have thought , it's was probably crap built by two guys in brown coats and an adze anyway !!!

You need a good modern fin keel and sail drive for blue water really

I note that I have had nothing but fin keel boats and have not lost a prop, and I always took race cars to drag races.

The fact remains "if you loose a "simple" cotter pin you loose your prop"(if a cotter pin is what holds your prop),all the "maintenance" in the world cant change that fact...

She looks like a fine boat, I have no doubt she will do the job. Thanks for showing it

[trapoc]

Honest I saw a guy lose his prop going down the Highway. It nearly took out my grill. True story

[trapoc]

Is a prop really that big a deal on a sailboat?

And I am sure its not 25 foot long,

They have races for these folks. We were anchored at Nelson's Dockyard in Antigua when the winner of the race a few years ago came in. He did it in 54 days which was an extremely good time. Second place was a double-handed boat ten days behind. I think there were around 20 boats which are very specially-designed for the purpose. There is an Englishwoman who has rowed the Atlantic and the Pacific and was prepping for the Indian.

Here's a video everyone should watch. A fin keel boat being put on the rocks just to see what would happen to it.

Very Very Good video, Puts paid to the hitting a floating container fear,

A few dents after that pounding, These boats are not as fragile as they look,

I did expect a hole after hitting that rock wall,

Great stuff Mate,

Its all a lie I tell you lies, these plastic boats are really all at the bottom of the ocean

Only if they have a hole in them, The bottom of them, that is, Hahahahaha


Seems its a bit harder to poke holes in them than I thought any way,

Well, after thinking about this for a few minutes, I'm left wondering how someone with the mindset of predicating the whole design of their yacht around retaining the propeller could possibly then employ a shaft/propeller that relied solely upon a "simple cotter pin" for that connection?

Seriously, the only prop design that I can think of which does rely upon a cotter pin is in small (~ 2 hp) outboards. All the shaft connections with which I am familiar employ nuts to force the prop onto the taper of the shaft. The nut is indeed often then secured with a cotter pin, but sometimes not... then using a jam nut instead.

The whole point of my thinking is that to say that a full keel/attached rudder is necessary to assure oneself of never loosing their prop and thus this is required for "Bluewater cruising capability" is a bit extreme.

Finally, I bet that your long keeled yacht has a whole lot of cotter pins securing clevis pins in your standing rigging. The loss of any one of those cotters can lead to the clevis working its way out, and then the mast falls down (I know this from personal experience, BTW). How could you possibly go to sea thus endangered?

I guess it is all about prioritization of risks...

Cheers,

Jim

Impressive to say the least!

Its pretty weak when you have to defend your boat on the fact of a small pin falling out..
Next thing you you'll see is someone inventing a basket and selling it to fin keeled boat owners that will catch your prop when it falls off..
And chances are, they will make money on the idea........

I'm thinking he was just " spinning up " the fin keel crowd. Just pouring a little gas from his gas can on the existing flame.............
