Hurley 24/70: couple of n00bish questions...

[Reptile Smile]

Hi all,

I bought the boat dis-masted, and want to re-step the mast as soon as poss. I measured the hole through the tabernacle as 10mm, but at M10 bolt is a tiny bit too big. It would originally have been imperial, of course (accursed system) - am I right in saying it's most likely to be 3/8"?

Also, I'm struggling to understand my stern gland - I can't see a grease tube anywhere. is this one of those new-fangled maintenance-free ones that doesn't have a grease tube you turn?

BTW, the 1GM10 engine is allegedly seized, but I don't have a hand-cranking handle to test this. Can anyone suggest somewhere I could cheaply obtain one?

Reptile Smile,

have a good look in the bilges beside the keel; there was a 24/70 at our club with a keel which really did wobble like a jelly laterally, when the boat was being transported in the hoist a small crowd would gather just to watch this hypnotic effect !

Hopefully that was a rogue boat, but have a good look around yours; a dark night with a F6 as you claw off a lee shore is not the time to start wondering if the keel will stay on...

If she's ashore resting on the keel it will be hard to tell, the only clue I can think of would be stress cracks - so fresh bilge paint might be a warning, if so get to work with thinners and a wire brush or similar.

I can't see any pictures. A socket on the crank pulley will let you turn the engine by hand though.

Seajet: Checking the keel bolts is surely sensible on any boat. I don't there's anything about Hurley's that make them any more or less likely than anything else to suffer failure, though - they have an envialbe reputation for sea-kindliness.

Tammany: The crank pulley - is that the lower of the pulleys on the alternator belt? (In the manual, it's labelled as the crankshaft V-pulley, so I presume it's that?)

I thought the keel on a Hurley 24/70 was part of the moulding and didn't have keel bolts.

I thought the keel on a Hurley 24/70 was part of the moulding and didn't have keel bolts.

This bilge-keel version seems to be bolted on:

I can't see anything that looks like the cut-off stub of a moulded-in fin keel, so if there was a fin version then presumably that was bolted on too.

I lived on my 24/70 fin keel for about 3 years, never had any leaks or keel movement, the ballast is encapsulated by the way.

All these questions, and many more, are dealt with on the excellent Hurley Owners Association (HOA) website, which is about £10 a year membership.

Has the coach roof been strengthened, some of them get squashed down by the mast foot. A good time to do this is with the mast off!

Hurley 24 fin keels are definitely moulded in and I thought bilge keels were as well. Some have lead ballast and some iron so try to make sure the ballast stays watertight. If iron and it starts to corrode you will have problems with expansion.
I can't open the picture but mine certainly had a conventional stern gland so if you don't have a greaser in the cockpit locker I imagine it has been changed for something like a Volvo seal as Vic says.
Definitely worth joining the owners association as there is a huge amount of technical information available

If this is a tabernacle mast foot (like my H20) then just drill it out.. I plan to do the same this year to make fitting the bottom bolt a little easier...

A friend bought a Alanter25 a few years ago and had to replace the mast support beam as water had leaked in and caused the coachroof to sag.

Also had to get the keels reinforced as they started to leak at the hull join.
They are rather large keels on the twin keel version and repeated sinking in to deep mud may have loosened them.

The owners web site gives us the Info There are No actual "keel bolts" but fin and bilge keel are encapsulated in mouldings which are then bolted onto the same hull mould.

"Interestingly there was only one mould for the 24/70. The keel combination was made up by bolting modular keel moulds into place which provides the moulded bulb keel shape that is so useful without the need for keel bolts that provide so much trouble for owners of other makes."

 

[Seajet]

I'm quite sure the fin keel 24/70 I saw ( we all watched it's wobbly progress for several years of launches and recoveries ) had a moulded keel, an integral part of the hull moulding - no joins or bolts.

Which is why I suggested cracks in the bilges around the keel may well be the only way of spotting anything untoward.

I have often wondered about that boat, as Hurleys have a good name and surely all the 24/70's can't be like that one; all I can imagine is it may have been a Friday afternoon job - " I thought you did the final layup coats ? " - " No, I thought you did them ! "

P'raps a pioneering form of canting keel!
