The one that came when I bought the boat is pretty much shot. I have called into the local supplier @ Deacons twice but failed to get either a budget estimate or measuring instructions so I can get a firm price. Last week they promised to call me but never did.

I also need a cockpit cover.

Anyone got any recommendations?
 
Try 'RAIN and SUN COVERS' in Bevois Valley(02380 348854) ask for Phillip Bull, they manufacture and repair boat covers and anything in canvas,acrylic etc.

He lives locally and is a fellow club member, (sails a beautiful Osprey) otherwise no connection.

My sail cover / lazy jacks were made by CJ Marine (http://www.cjmarine.co.uk/) a few years ago and they have lasted exceptionally well. I take them to my local sail centre every other year for laundering, and each time receive positive comments on them and how well they're made.

Would definitely recommend the quality - although I don't know what they charge as the items in question came with the boat.

I have just bought a sail cover with 3 lazyjacks from Crusader and a sprayhood from severn sails. Both are excellent workmanship and fit well.

Sprayhoods are a particular issue since the maker really needs to be close to your boat to ensure they fit properly. I was keen to have the new cover fit on the same poppers as the old one so I could continue to use the old one with the boat laid up etc.

The sail cover from Crusader was made to my measurements and very accurately at that. It doesnt have the usual bonnet but instead has a zipped on front piece that goes round the mast and the pole - the jury is out on whether this is an improvement or the reverse. It also has a strap on the aft end to close up the cover since I am plagued by birds roosting in the main sail and sh*tting all over it. TBH I was uneasy about ordering from Crusader because they are cheaper than many others. I was wrong, the quality is excellent and I shall use them again.

I've just bought a sprayhood and mainsail cover with lazyjacks from CJ Marine. Quality is very good. And I had an awkward sprayhood shape. BUT .... the invoice was laid out in such a way that suggested that the hood and mainsail cover would both be fitted. Actually, they only fitted the hood, and then left the mainsail cover in a bag with instructions. I am hopping mad. Fitting it involves slitting the sides with a knife to put my reefing lines through, and I am convinced I'm going to slit it in the wrong place. And it's made for a main with a boltrope in the foot, whereas mine is loose fitted. Cost if I'd have had a standard shaped hood would have been £1375. Cost because I have an awkward hood was £1635 (for both). These quotes were comparable with three or so others I had. But I'm still steaming that they are not fitting the mainsail cover!

for a loose footed main fit the stac pac with a bit of rope of a suitable diameter tack stitched along the bottom and slid in along the boom

Used him for various canvas/canopy work and I have been very pleased. And he is close to Deacons, which is handy for measuring etc.

I've now bought a sensible length of rope, which I hope to just slide into the boom groove to hold the main bag down, but I'm certainly not going to stitch it in! They came to measure for the mainsail bag, so they should probably have provided the rope to make it fit. (Sorry about the thread drift to the OP)
 
Have just received a lazy jack system from crystal covers in Portchester. Seems a decent piece of kit (not been on the water yet) with zips for reefing lines to go through. Only (minor) annoyance is the mast bonnet thingy fastens under the boom with rope through an eyelet instead of a more convenient system though I dunno if thats standard.

I too failed to get any response from a swanwick based supplier but got quotes from crystal and CJ based on the length of my boom. Crystal were cheaper and did the proper measurements themselves while that seemed to be extra with CJ.
 
Another vote for Crusader

The black clips are to roll the stack pack away when it's not in use

I remember reading that a stackpack sail cover when left in situ can increases the drive from the mainsail by acting as an end-plate on the foot of the sail and reducing the loss of pressure differential between the two surfaces of the sail due to airflow round the boom. It is of course this pressure differential that drives the boat. I think the research and testing was carried out by Dehlers.

If this was the case I would have thought that the racing community would have picked up on it, wouldn't you? :)

I personally have my doubts because the lines for the stack pack would effect the laminar flow, likewise the the bag flapping around at the bottom would disrupt the airflow on the sail surface. The boom itself would act as a end-plate, the same way a bulb on a keel does, to prevent or reduce wing tip vortices

Looking at it very simply, I paid for all of my sail, and I'm going to use it all.:D

One owner. a renowned racing man a few years ago, used to remove his stackpack when racing his family cruiser/racer. He reckons that he forgot one day, and found the boat actually going better - he put it down to an endplate effect, similar to winglets on a modern jet. I only repeat this for what it's worth, I haven't got a stackpack.

I've also seen a comment (similar to another poster) about the speed-enhancing possibilities of Stackpack canvas - I think written by someone at Dehler yachts (which I believe supply their own system on boats) who used it to good effect in their club racing.
