Effect of Stack Packs in Storm Winds

I just added stack packs to my main and mizzen, The main pack is about 50 square feet and the mizzen is about 20. I have done searches on this forum and Google to understand the effect of the packs in storm winds- 40+.

Anyone out there with experience in high winds with a stack pack equipped ketch?

Read one post that referred to the packs as fixed sails. Would almost seem to be an installed set of storm sails. (Until the pack fails and dumps the sail!)

Thanks

Re: Effect of Stack Packs in Storm Winds

I have, just roll both sides and tie along the boom, the first time i dont realize can be a problem until a jib sheet cacht a batten end in fron of the mast and leave me with no other option to cut the jib sheet because the sheet entangled to bad around the battem... so if you plan to sail in serious weather my sugestion could be roll out both sides , also reefing is more easy if you need to visit the boom for reefing.

Re: Effect of Stack Packs in Storm Winds

I doubt they sail to weather very well as storm sails. I like having them in place when reefing, as they collect the loose sail base nicely.

Re: Effect of Stack Packs in Storm Winds

My boat tends to sail on the mooring on hull windage. I fitted my stack pack-lazyjack connection with St Steel sisterhooks. Quick release and wrap it tight with half hitches. Reduces windage b y 2/3.

Re: Effect of Stack Packs in Storm Winds

I fitted mine with quick release clips. When I'm gone from the boat for a while or expecting high winds I release the lazy jacks, leave the pack zipped up and put the old sail cover over the whole thing. It reduces the size significantly and keeps it all water-tight and covered. When returning to the boat I just remove the cover and clip the lazy jacks back in place. I then can unzip and raise the sail like before. In very high wind cases where I'm going to leave the boat I remove the boom with the sail, sail pack and everything attached and put it inside the cabin for storage. It's not easy but it is doable with a little help.

Re: Effect of Stack Packs in Storm Winds

'Consider the boat's handling characteristics--a lighter, less stable boat would be more vulnerable to the windage of the stack pack in heavier winds.

I release them and clip them to the mast at boom height. The sail cover then fits neatly.
