At our Club, we are trying to get more folks active in the sailing of Hobie's. One of the issues is that 'the equipment is too heavy', another is 'difficult to right'. Many of our potential sailors are less than 200 lb and 6'2", so we experimented, and I'm asking for Forum feedback.

Based on our experiences sailing a boomless Hobie 15, we took one of our old H16's, and removed the boom to make it easier to carry the sail-boom down from the Club House to the beach. Then we had a sailmaker install a grommet in the foot of the main sail, (vertically above the rear crossbar), which is where the upper blocks attach. (Next weekend, we will further modify this by rivetting aluminum plates 4" tall by 18" long to either side of the mainsail in the same area of the foot, with a hole drilled through in to accept a shackle for the upper blocks.)

One of our members got all excited and said this is 'dangerous, and Hobie Corp would never build or authorize something like this.' Great Scott, isn't sailing sometime dangerous?

IMHO, while it may not be "authorized", how can it be dangerous? We are depowering the mainsail, we are removing a boom on which folks can bash their heads. We are making the boat lighter, easier to right. (Oh, we also added shroud extenders and a mast base keeper to make righting easier.) Anyone else tried anything like this? Problems? Successes?

I know what Matt M will suggest - something along the lines of 'why not buy a couple of Waves?' And he may well be right. Opinions please.

Sounds like the Hobie 17 sport "Boomlet". A short section of boom at the aft end to support the leech, but the sail is "mostly" boomless. You also need a bunch of sail reinforcement patches.

I'd also like to get a boomless sail made. unfortunately i drive a tiny 2 door lexus and have to get my roomate or a friend to come pick up my sails every time i want to go out! it sucks! but if i could find a boomless sail i could fold it up a little tighter and fit her into my car. fortunately i can leave my cat on the beach year round so i just have to transport sails back and forth.

Have you tried removing the sail from the boom for transport?

no. but its the size of the boom that wont fit in my car. so that wouldnt help. I guess i could leave the boom on the hobie at the beach but i think it would get stolen or have kids climbing on it or something.

I ran two training courses this last weekend, something we call 'Cat Chat'. About an hour of me yakking and asking questions, safety issues, history of beach cats, safety instructions, sailing differences between monoslugs and multihulls etc. I also demonstrate rigging, righting, launching etc. All of our students have previously qualified to a minimum of White Sail III, so this is part of our Club's contribution to 'growing' their sailing skills.

Then I took two students out on the modified H16. Winds varied from 8 - 12 knots, and fairly choppy. I handled the sheets while they got used to stalling during a tack, and whipping around on a gybe. The modified mail sail was fine, other than recognizing we will have to install a plate and/or some more reinforcement on the foot of the sail.

On the last run, the wind picked up, and on a screaming reach, we planted a hull, raising the stern up high. I released the main, but was not quick enough to release the traveler as I was busy sliding down the tramp. Good experience for the students, how to recover from a capsize, plus the water was not too cold.

Now this, from Sunday's sailors :
"All, Jim P. and I took the opportunity to take out the modified H16 on Sunday afternoon after John's on shore course. Although at times the winds were on the weak side, they were certainly steady enough to sail and to get a feel for the boat. The main sail held its shape reasonably and seemed secure; however during gusts I did fear a bit for the grommets as they are currently installed. (I agree that the proposed aluminum plate should rectify this).

Overall I think that it sailed quite well, maneuvering easily and predictably. We successfully tacked and gybed several times without difficulty or incident. In fact I don't think that we even stalled once ;-) Further, it seemed stable throughout all points of sail. Having said that, I should admit that I have not sailed an unmodified H16 for some time and cannot be completely sure of the differences in terms of performance.

It is fair to say that I found it quite comfortable to sail without a boom "threatening" on each tack and gybe. Also adding to the comfort, there is slightly better visibility and more room on the tramp.

With the addition of the aluminum plates to reinforce the foot of the sail as proposed, I don't see any issues with this configuration. Further, as has been mentioned previously in this thread, in terms of safety, I would agree that this new configuration, both with and without the extra plate is actually safer than a stock H16. It removes the potential of colliding with a boom either during normal sailing or during a dramatic capsize. Although unlikely after adding the reinforcing plates, I don't think that tearing a mainsail would be a serious safety issue since it should still be possible to sail with the jib if this were to happen. Has anyone tried sailing with just a jib on an H16?"

So far, so good.

i have been experimenting with a modified "batten boom" to address the weight, ease of set-up, and concerns about a solid boom during tack/gybe. the configuration is a flexible plastic plank the same length as the boom with the sail sewn around it. aluminum plates are attached on either side of the boom/sail to attach the mainsheet blocks, making a boom/sail sandwich.

benefits are:
- the "batten boom" is flexible, soft on (most) impact
- much lighter and easier to carry
- allows for the entire sail to keep its shape (flexible)
- stiff enough to allow for support at the foot
- sails fine for recreational use and actually seems to stall less in tacks since the boom doesn't force so much of a weathervane-effect.

downsides to this design are:
- you must use ~6 inches of the sail in the wraparound at the bottom which is a bear to sew and likely impossible to undo
- the head of the boom where it attaches to the mast is a bit awkward and i think is putting too much stress on the sail, to a point that the sail may tear eventually where it enters the mast track.
- i don't think the majority of the length of the batten boom is necessary (meaning the "boomlet" idea makes more sense)
- there is still a considrably thick, solid object swinging about during tack/gybe maneuvers

I am considering modifying an extra sail to go boomless for light recreational trips. Anything new here?

Has anyone tried a stock boomless sail from another boat on an H16?

Any known good (or bad) configurations would be good to hear about.

My friend has a Hobie Getaway, looks like you are aiming for a similar boomless sail.
