Guys,

Derek and I took the 18 out for the first time this weekend... (Sailing experience: Scott - a few vacations on a Sunfish. Derek- a few vacations having drinks on some, "boat with a sail".

(Friday)

We departed under tow of my buddies bass boat with sails furled. We chose to do this because of reading previous posts about the Hobies being ready to sail before the crew. We thought it was the safest option for the first outing. After reaching a satisfactory location, Derek raised the sails and I manned the rudder and sheets. "I'M SAILING" (Bill Murray) Wind was variable a 4 kts or less. We had forward movement for about 30 min., thats about it...
Furled and got towed back in. Good experience to do a full set up and tear down...

(SATURDAY)

Same deal, out under tow. Wind South at about 8kts. Sails up and gone! I love this thing! I don't know how fast we were going but it was probably about 45kts. OK, maybe 10mph.
We sailed to the other side of the lake to UW Wisconsin, Madison, Memorial Union. Dropped the main about 300 yards out and went in under the jib. Dropped the jib about 10 feet from the dock and ran out of forward momentum as Derek grabbed the pier. Had lunch and headed back down wind across Lake Mendota to the marina. We made a 180 into irons dropped the main and let the jib spin us back around then about 100ft from the boat ramp furled the jib and went in under the wires (took that from Mr. Lightfoot). Up on the trailer and back home, no worse for wear. Cant wait to do it again.

What we learned or need to learn:
We need to paraffin wax the main sail. I was very hard to get the last couple of feet up.
We need one or two cleats at the bottom of the mast for lines.
We need to understand better how properly unhook the main sail ring/hook from the top of the mast, seems cumbersome.
We need to learn now to properly trim the "slot" between the main and the jib.

What a blast!

Congrats on a great start! All things will be learned with time and experience, and there is no better teacher!

That said, if you want to trim off a few years of the learning curve, I'd highly suggest picking up a catamaran sailing book. They all have about the same information, but I'd recommend Catamaran Racing for the 90's. It's got the most up to date information and really explains how to get the most out of your boat, what to adjust and why. For a boat like the 18, with all the possible adjustments, it really explains what everything does well. Some of it'll be information overload at first, but as you improve, more and more of it will "click" into place. The chapters on boat handling are invaluable to a beginner, and the boat tuning becomes more useful as you gain experience. I like to read it once a season or so, just to try and absorb it all.

A few notes based on your lessons learned:

1) Always point the boat dead upwind when hoisting the main. It becomes impossible if the wind starts to grab the sail. The only way you can hoist it on the water is if you're being towed upwind. The top few feet is always a bit tougher, but a non-greasy dry lubricant or wax on the boltrope/mast track will help.

2) Careful drilling into the mast or crossbar. You can end up with a leaky mast or a weakened crossbar. The best recommendation is to coil up the main halyard and excess downhaul line and stuff it in a tramp pocket.

3) Unhooking the main can be complicated by the "flopper." If you have an older boat, it has one of these devices that "flops" up or down. The idea is that when raising the sail, you'll want to get the ring just above the hook (but not above the flopper) and let it "set" down into the hook. To lower it, you just pull the ring up out of the hook, past the flopper, and let it come down. The flopper "flops" down and "covers" the hook, preventing the ring from hooking and allowing it to slide past. It makes lowering the sail easy, but raising it can be tricky - like I said, you have to go just past the hook, but not past the flopper. If your mast doesn't have one of these, or if it's been removed, you just need to raise the ring up past the hook and then let it "set" into the hook to raise it. To lower, you'll need to raise the ring out of the hook, ROTATE the mast CLOCKWISE so that the hook is rotated away from the ring, and then let it slide down the track.

4) Trimming the slot can be a little tricky, and proper jib trim is a subject covered at length in those catamaran books. Basically, you want the main and jib to have the same shape. If the main is in tight, so is the jib. If the main is loose, so is the jib. Tell tales help immensely in figuring out how to properly trim the sails. The book that I mentioned has specific recommendations for proper trimming and tuning of the Hobie 18, specifically.

Another highly recommended book is the Hobie 18 Performance Manual, available online at Murrays.com.
