seems a miss to create a class without making the j 24 more comfortable/less expensive. flattening her out without railmeat makes a lot of sense. But why slow her down and require 3 to run her. I vote:

  • keep the traveler and primaries since they are already there
  • switch to a 120ish headsail on a roller furler
  • allow the main to be roached out
  • ditch the lightweight sailcloth and move back to more durable/less expensive materials
  • add a portapotty

I don't see the value in removing the pulpit or stern rail

 

I have to agree, it is one thing to simplify the sail plan but why loose valuable things the boat already has. Sailing short handed? Drop the traveler..

In the old days we carried a 120, don't ever remember racing with it. We carried the 150 to around 18knts then dropped to the 100. It makes total sense to optimize any boat but why take it to a point that you can't sail OD anymore. The idea is to be able to do more races not less...

eX 24 “Sierra Hotel”  prototype will have a traveler less main sheet like below. Also 2 ratchet blocks per side for the spinnaker sheets and guys. 4” to 6 “ Longer forestay and standard J 24 sails.

The prob with the j-24 is if you rake the mast enough so you have helm the boom can go under the 24" lifelines in a jib! Can make you go swimming.

Putting 4 shorter stantions in. U have any ideas on what the length should be? Standard j 24 is 24” would like to have the legs out on the sloping deck.

How about using the same one's they use on a J/70?  Should be readily available...puts lifelines at 305 mm above sheer, or just over 12 inches...(12.0079)

12” is good, 14” is also common. Minnie’s has crates of used ones of many lengths. Long Dead J 24s in the Club dry sail lot are showing preparations....

Or pick a length, and cut down the current ones.  14 probably easier to slide under, esp with the sloping deck.  Also makes a more comfortable back rest for driver/trimmer.  Neither is high enough to not be a trip hazzard, so that's not a factor in the decision...

Sailing the eX 24 prototype with spin / guy sheets just 2  big harken ratchets per side, No winches on the boat. Any thoughts?

Winches are for genoas.

 

Edit: ratchets on the rear can be problematic. Be sure you can turn them off. Never had much luck with autos turning the line 180 degrees and releasing.

These are old harken ratchets with knobs. I’ve used double ratchets on melges 24s but not symmetrical kites. Thx

Windward sheeting with trimmer to leeward?

 

Not a good thing!!  We cross sheet to the windward primary on the Soverel 27, when we have enough breeze to need all the crew weight to weather....

How many changes are you actually making? Am I wrong to say that there are no changes to the hull besides stanchons pulpits and winches?

Took off winches, put Stainless Steel carriage bolts in the holes.

How would a retrofitted full length batten or two go in the top of the main and jib. That way you could blade them out and depower without flogging the shit out of them. This might fix some of the shitty shape issues with older sails . 

I'd also like to see a floating jib lead system with inhaulers so you could depower the jib in a gust quickly and power back up without messing with the sheet to help keep her on her feet with only three crew. 

It would be interesting to try a slightly longer pole. Might need a bridle for the lift and downhaul to stop it bending?

These could be very cheap mods to an old suit of sails, and it would be easy enough to go back to class in the future if you wanted to.

Why not just fill the holes with a suitable material instead?

Also, bolting on a keel bulb can't be any more expensive than replacing a deck.

 

And the keel stub is going to absorb the extra bending moment how?

I'm no engineer. I was just brainstorming how you could make a J/24 less crew weight - dependent without depowering it to the pint that it is no fun to sail.

5 people crew was de rigueur back in the day. 3 crew? Good luck. It is a big dinghy. Maybe trapeze and leave the genoa ;-P

Yeah, traps is just what you want for geezers who no longer want to deal with a kite?!  LOL!!!

I say cut the keel off put lee boards on it and use a crew of 8.  That be a lot more fun.

That way you can return it to  a J 24 if you wish.

See I C 24 s  more rake and floating jib leads should handle it under 22 knots

That’s why we are using standard j 24 main, jib, spin. A longer forestay fixes many problems with the boat balance.

eX 24 prototype with max mast rake. Forestay is adjustable for those who are squeamish.

Finally Sailing! 4 to 6 knots true. 1 degree of tiller angle slight weather helm to neutral . Shadowed the beer can racers, she’s very fast and high. Liking the mast rake similar to the J 22 or a Lightening 7 degrees aft. Thinking we will take and inch out or the forestay for the heavier stuff? maybe remove the fwd and aft mast chocks ? PHRF Northern CA rating with no Genoa 177.

She is very light and tippy at the dock, we had a 25 year old spinnaker in a dying breeze. Hard to tell. Far too much beer and high fives to get serious. We will set up a frackulater for the next sail. Will go with a simple bridle backstay no pinching setup to get more slack downwind.

6 degrees rake is becoming the AP setting. Took 1” out of the forestay. Using a Home Depot plastic adjustable framing or truss square.

9/2018  update. Old pic. Mast rake is now 5 degrees or 3” longer than max will be the AP setting for now. She points very high and is deadly fast 12 knots and under. We ditched the pinching backstay adjuster for a block on backstay and bridle rope on a 6 to 1 harken. Also removed the fwd deck chocks to get more mast bend.

If you didn't wack the crews heads before with the boom, surely you will now :rolleyes:

For you sissys you can punch a flatting reef grommet in or shorten the leech like a J 22. "Magic Pony" bike helmets also work. BTW the CA J 24 fleets are dead and good boats with trailers can be had for less than $4000.

As you are modifying a standard J24, just get a two foot longer boom and mainsail foot. Plenty of helm balance then and faster all round....

Yes true,  but we want to use std. J 24 sails too rebuild the class. The eX 24 is points very high and fast as we configured even in the lite stuff.

Second hand J24s are cheap enough, instead of messing around with minutia, which still cost money, go for the bigger main and scrap the Genoa. Savings on sail replacement will pay for the mods pretty quickly.

And you woud have a faster better balanced all round boat.

The fixed length forestay rule helped Ruin the class. Blueprinting the boat moving keels, shortening rudders, masts all cause the stupid forestay. If the class with std. sails won’t take off then we will roachout the main and use our masthead express 27 spinnaker.

This pic is 3 3/4” longer forestay. a I C 24 has 2 9/16 longer forestay. The gray mast behind is a Olsen 30 with no rake.
