I swear I read somewhere the slot for the main has to be 18 inches from the deck.

Anyone have a number for me where the fixed gooseneck is supposed to go?

John,

Do you still need the measurement? We have a Capri 25 in our Marina that has a fixed gooseneck. I'm headed over to Kami this weekend, do you want me to take pictures and measure that fixed gooseneck?

Fleet that would be stellar if you could. My thoughts are it's supposed to be 18 inches from the base of the fixed goose, to the deck. I was looking at the slide on my existing gooseneck, and it has very little travel room (as there are fixed screws in the mast that prevent it from sliding too low, and the bolt-rope slot [term] prevents it from going to high)...

I can see the mast band location on the top of the mast (stain on the alum), but don't have one for the bottom, or rather don't know where it might have been. I know the max-luff of the mainsail is supposed to be 28.5' and was thinking of measuring down from that band, with some SWAG, but I don't wanna install the fixed goose, only to find I put it too high and can't properly tension my brandy new main correctly (and I don't have that main as yet to check). There is no hurry on any of this as I won't be able to step the mast for a couple more weeks, and even then I'd only do it on dry land in my driveway... Season starts for us May 1.

So many projects, SO little time.

Just a note to consider, my mast has NO screws preventing the gooseneck from going to the bottom of the mast. I have a sliding screw stop that I can position to hold the mast at a minimum elevation.
I've not seen any evidence of screws either. I'm suggesting that your stop screws may not be factory.
I don't have enough knowledge to weigh the pros and cons of a fixed gooseneck, but I have to surmise that the floating gooseneck had a purpose in the original design.
Just food for thought.

The sliding goose has 3 purposes... 1) to allow the mainsail to be hoisted to max height with ease. 2) to allow one to easily drop the boom onto the mast. 3) to provide a spot to attach a boom downhaul.

You are supposed to use a downhaul with the sliding goose, to tension the luff on the fly... you get max height on mainsail, then tension the luff using the downhaul on the sliding gooseneck. Frankly I am pretty old school, and would prefer a fixed goose, and tension the mainsail luff with halyard (but then that's also how I approach my jib). Since this boat has primaries for halyards only, I don't see it tough to tension with the winch.

Oh and for the record, the cunningham is supposed to adjust draft forward with excess luff tension, and if the goose slides it creates an unwanted effect under the cunningham if there is no downhaul on the gooseneck slider (weird bag). http://www.youtube.com/watch?v=Gxg4k6c3XFo

This is all just a matter of preference... Since I sail alone a lot, I like sail controls, but I want the least number of lines to get me there.

Oh here's a shot of the screw stops that seem fixed (but I suppose I could unscrew them and see if it can move)... Note this is the only picture I have without a cunningham that keeps one from seeing the screws. It should be noted that the vang also keeps the boom from lifting a bit. Oh, and this is the worse sail trim I think I've ever had... the outhaul is loose, the cringle is all messed up, there is no cunningham... and the jib is too far outboard.

John; If you look at the Capri 25 owners manual (pdf) you will see a drawing of where the top of the boom is located from the bottom of the upper mast band (actually 26.50' which is also known as the P dimension on a sailboat) Mount the gooseneck (fixed) to line up the top of the boom at this point. Don't be concerned with height from deck.
Also, most sailmakers today do a 'floating' tack on the mainsails which is merely a slug at the tack that slides into the mast bolt rope slot. This does away with the need for a shackle at the tack and all luff adjustments are done by the cunningham. The purpose is to allow constant changes to the luff while sailing at various wind angles.

Ok, that's what I was hoping 26.50' from the band, which is exactly what I had thought, thanks for the confirm. THIS I can do.

PS: I could use some writers for tech articles on the Capri 25.

Fixed gooseneck from another Capri 25. This Capri is very fast and the owner knows how to get the max out of her. I think he uses a Porpoise or Pineapple main sail and not E/P. Not sure if the cut is different. Base of mast to the bottom of the gooseneck opening is 31.5"

Hope this helps

Wow, higher than I thought. Yes, I've seen the pineapple mains. Talked to the owner actually, and they have tweaked their Capri 25 design, and I think they are onto something. However, I like Harry, and the deal he's giving to "bulk purchases," and it was a tough decision to go with them.

I have to admit, I'm NOT going to be the fastest Capri sailor. I'd actually consider it an honor if I could even keep up with the guys who sail these things all the time. However, with 30yo sails, I had NO chance.

Anyway, I really appreciate what you and Jim got for me, and I can do a sanity check on my own boat, and verify these settings, before I drill holes in my mast. I may also add to that waiting until I get my new main, to make sure everything lines up properly before I fix the goose.
