Hi, I'm considering calming my 41yr old Tempest down into a more "gentlemanly" day sailor for my family and I.
My main concern is the head clearance under the boom.
I'm considering having 12" taken off the foot of the sail to lift the boom but would like a bit of advice first.
Should I just have some reefing cringles put into the sail 12" above the foot rather than have it cut?
Will lifting the boom by 12" make a dramatic effect to the balance of the boat?
The clearance is ok at the moment if I'm single handed but with a couple of (not so experienced) crew I start to twitch a bit.
As I mentioned earlier, I just enjoy the day sailing with family and friends and dont race or hang off her on a trapeaze.
Any advice would be great,
Dave

I'm no sail designer or engineer, but if you left a way to lower the sail so the boom is in the original place and shortened the sail so you could sail the way you plan to, that would leave you something to resort to if the wind got too strong. You could accomplish this with a dyeema or other modern fiber main halyard, and a different method of cleating than the wire loop and hook on the mast that I have on my 31 yr old.
Just thinking if the sail is up a foot higher and you get in a big wind, it might get dicey. If you could lower the boom, it would be just like a reefed sail on the original boat. You could just do that and get some reefing points installed on the original sail.
Just thoughts. Ask North Sails, or someone at Proctor.

I'm not sure that made sense. You could sail with the halyard all the way up, and have more boom clearance, and if need be, lower the halyard so the boom is in the original place and have more stability.
Good luck,

Hi, Thanks for your advice, I think we are thinking along the same lines.
I've fitted a cleat on the mast now to do away with the wire loop and hook, and the sail is booked in to have a couple of reefs fitted next weekend. I'll let you know what difference it makes to stability in a good blow with the boom raised for head clearance.

Let us know. I bet the loss of area will offset the elevated boom as far as lateral stability, I bet it doesn't point as well. It will be interesting to see the effects.

Fitted the sail today with its new reefing. Sailed with the 1st reef in, and the boom raised about 12" to give extra head clearance for around 10 miles, covering all points of sail in a fairly steady 15 knot wind.
I was surprised that she pointed into the wind just as well as before, and she is only slightly more "Tippy" in a strong gust but is still nice and stable.
In fact I'd say it was a "Very civilised single handed sail!"
Happy Dayz
