Re: Small main sail, large jib - questions

You're likely to reach at 2kts when hove to, and you'll probably be sat at quite an angle to the wind/waves. Depends on how powerful your rudder is too. All a big balancing act, as Faster says, give it a go and see what happens

Re: Small main sail, large jib - questions

I have not seen Tenuki's boat out much. I can get ahold of him if you want some info on this boat. The Ranger should not broach as much as an SJ, due to different hull designs IMHO. Should work well around here in puget sound, lk washington etc.

Thanks, yes, I'd love to get in touch with any Kent Ranger 24 owners....

Depends where you are sailing and what you're after. If you are just noodling around Lake Union of an afternoon, reefed main and smaller headsail will take you anywhere. Just put a preventer or boom brake on, and accidental jibes aren't that much risk. DO remember to blow the preventer before an intentional jibe, or you will be washing your windows.

If you just want some lazy reaching-back-and-forth, deploy the big jib and keep your main in the stackpack. You'll get good speed & low stress jibes. Small mains on these boat can mean poor drive, esp. in chop. You'll need some speed on if you hope to tack thru the wind.

Big breeze, open water, long hours downwind, lots of sailors prefer double headsails anyway. Saves chafe on the main and keeps the pointy end where it belongs. IOR boats are actually really good for this: your roller genoa (or a light blast reacher) flying to leeward, a smaller, high-clewed headsail poled out to windward. Many people will use a 100-110 for that. You can fly the second sail on an extra forestay, or on its own luff, or in the second groove of the furler (if it has one & can take the loads.) It's a bit fussy to jibe, so not a tactic for narrow waters.

IOR boats can make very good cruisers if you twiddle the sailplans a bit and don't horsewhip the boat downwind. You can actually lengthen the boom and mainsail foot w/out messing up rig balance on these boats, but most folks just do what we have planned: put a full-hoist G2 on a furler as your everyday working jib. Use a light Code0, gennaker, and/or spi for winds less than 10kts -- easy to handle, stows tight, drives the boat to hull speed. Roller-reef the G2 to stand in for the G3; add a solent or babystay to carry a staysail genoa and/or storm jib when it gets snotty. Mainsail requires little attention; many IOR owners don't reef it til ~30kts.

Here's a tentative sailplan revision for our Ballad:

revsailplan

The 150% G1 is replaced with a higher-aspect 138% on a furler. All our other sails are set flying -- a nylon 150 for light days (removable furler to the anchor platform), a 100% spinnaker staysail/staysail genoa for winds in the 30s, and a 50sqft storm jib hoisted flying on the spi pole topping lift. When the main needs replacing after a few seasons, we may opt for a longer boom.

I'd prefer a more balanced rig, but most of the boats we have to choose from in our price range are either narrow, heavy, traditional voyagers, or IOR-optimized racer-cruisers with livelier sailing characteristics but large headsail inventories. We've chosen the latter path & will spend the needed effort to minimize sail handling. It'll be fine.

Re: Small main sail, large jib - questions

Update-

Been out a couple times in the new Kent Ranger. Handled heavy swell and chop right into 18-20 knot winds while I was motoring to its new mooring.

Also went out sailing in 6-8 knots. Moves well in light air. Went on downwind runs wing and wing with 130 headsail. The small boom is nice in a way since it made me less concerned about unintentional jibes..... but that leads me to this perhaps stupid question:

Doesn't having such a small main sail in these types of boats cost you a lot of speed?

Anyway, very happy with it so far.

.
The sail area for the boat is not usually 'less' than any other. It's a matter of distribution. So the sail area you've 'lost' in the skinny main was made up for in the larger headsails and the (relatively speaking) big spinnakers.

If you're not flying a kite then you might lose some area downwind unless you pole out your genoa. When it's windy the smaller jib and the main will be plenty.. esp down low on your learning curve.

Re: Small main sail, large jib - questions

Also, while the main has a short boom, it is a high aspect ratio main. Upwind the luff height generates force, even though the sail is not wide. Few would argue that IOR boats do not sail well upwind.

Get that 170% genoa, that oversized masthead kite, and that extra long spinnaker pole and start enjoying that boat's speed. Just beware of the death rolls...

Re: Small main sail, large jib - questions

Thanks... another stupid question:

Can I use the spinnaker pole as a whisker pole to pole out the genoa?

Re: Small main sail, large jib - questions

Sure, although it may be too short for a larger jib. It also does not suffer the same compression pressure, so you can use a thinner, lighter extendable whisker pole to pole out your larger jibs. You can attach a topping lift to the end of the whisker pole to keep it from dipping in the water.

In racing, you will be penalized for having a spinnaker pole longer than "J" (the horizontal length from the stem to the vertical line created by the mast). Similarly, I believe the foot of your spinnaker cannot exceed "J" x 1.8 and the luff cannot exceed 95% of the square root of "I" squared plus "J" squared without penalty.

If you do not race, you can use a longer pole and a larger spinnaker, subject only to your ability to handle them and ultimately your boat's dimensions. If you look at the old photos of racing yachts, you can see that they carried huge spinnakers on long poles to gain maximum sail area downwind.

Re: Small main sail, large jib - questions

Don't plan on racing... If the spinnaker pole turns out to be too short for, say, the 130.... would that absolutely preclude its use, or just mean that it wouldn't be optimal?
