Playing with different rig layouts

I've been meaning to get the boat accurate drawn in Cad for quite a while to play with sail types and dimensions.  Good way to get the CE close to the right place before actually building and putting it on the boat.

 The sail above is pretty much the one I've already built.  The geometry gibes with what I've found on the water.  I end up pulling the sail back for the right helm balance when going to windward.  I also drew in a sprit boom with the snotter about as high as I can comfortably reach, and it lays out pretty nice.  Since drawing this I've run both the running parrel and the downhaul into the cabin for easy adjustment on the fly with the hatches installed.  anytime I'm headed downwind, I'll want to move the sail back forward as it's shown on the right.
I've also been wanting to do a junk sail for the easy reefing.  I built one for a little trimaran I used to own, and it worked out great.  This is a sail built on the Vincent Reddish classic proportions using 10ft battens.  The area and balance end up almost perfect for my existing mast location.  This one will get built when I find the right batten material.

Hatching a new hatch Plan

These are the original "Quick and dirty" hatches I build for the boat.  Front with window, rear with window and the one for the top of the slot.  The fore and aft stored in the boat just fine, but the top one ended up being 59" long x 20" wide, and was a tough thing to stow inside the boat underway.  So Decided to cut it in half.  I ended up with 2 pieces at 30" x 20" that are easily stowed inside the boat in several places.

Obviously I want to keep the hatch joint freeway in the rain tight, so I built an interlocking joint.

I wanted something quick, cheap, simple and secure for battening everything down both on the trailer and on the water.  Shock cord and thumb cleats made out of scrap plywood work just great.

When the hatch was full size, I could slide it back and forth on the rails to stand in either end.  The thumb cleat and shock cord detail allowed me to secure it in many positions.  I now can just install one of them and have the other easily stored in the boat at only 30" x 20".  Good foul weather setup that allows me to stand provided the wind isn't too strong for the sail i have up at the time.  I don't show the rear companionway hatch installed here, but it most certainly can be, and leaves me a nice 29" x 16" opening to stand in well supported and protected.

In the picture above, you can see where the top hatch pieces now normally store.  I stuff them along the sides right behind the batteries.  Just quickly tuck them behind my Perma-bungees like I do with the throwable cushions to keep them out of my way when needed.  The fore and aft covers can get stuffed lots of different places being much smaller.

Aft hatch in the normal position with ventilation through the bottom, matching the opening at the bottom of the front hatch.  Rain tight but well ventilated.  I can of course wedge something in these openings to cut the airflow if needed.  In bug season I'd only need a little bit of netting at these openings.

The bungee system on the rear hatch lets me slide it down like this to ventilate out the top instead of the bottom.  This is what I'll probably do when using a cabin heater or cooking inside to keep from Asphyxiating myself.  The front hatch ventilates through the bottom end always.  The taper on the opening keeps me from sliding that one up or down like this.

The front hatch opening I've been talking about.  Also in this picture is another issue I've been meaning to deal with.  The Mast opening in the foredeck.  No good way to seal that with the mast in place, or even with it out of the opening in transit.  The hole is also flush to the deck, making any water on the foredeck an easy path into my front storage area.  But I found a solution.

More lumber from the scrap pile.  There's a reason i never throw away any wood bigger than a playing card.

The finished product (except for paint, bedding, screwing it down, and putting the rigging fittings back)

I can now take a plastic bag, cut a hole in the bottom and slide it up the mast before stepping it.  Bungee the bag tight to the mast and the bungee the bottom of the bag over this collar.  Whole mess raised off of the deck so only water running down the mast has any chance of getting in.

I'm now rain and spray tight.  Even in a knock down past the slot edge not much water should get it through the slot before she self rights.  If I have the hatches battened that is.  I have a little more lean that will allow me to put a window in each of the top hatch pieces to let me see the sail when underway completely enclosed.  More on that when I get it done.

No wind, so breaking in the Honda 2.3

Sorry there hasn't been much here lately, I've been working a lot and been having some truck issues so I couldn't tow the boat.  I've been playing with little details to fine tune the rig and sailing position.  I've moved ballast forward, re-rigged my lazyjacks to make them more useful, went to a smaller diameter mainsheet for less friction, etc.

The truck is finally all done and dependable, so I hitched up the boat and headed down to the multnomah channel of the willamette river.  No wind.  Not a problem, I'd purchased the new Honda 2.3 and it needed more breaking hours at low speed.  The video below is a quickie with the iPhone.  Throttle position is @ 1/4 to 1/3, and was getting me 4+ knots.  I ran for over 1.5 hours without having to add gas to the tank.  Not bad for a 15 foot displacement hull with @ 13' in the water.

Just as I got back to the ramp and was loading up, a front moved in with LOTS of wind, probably too much :-)  I sure like this little honda.  The boat makes a fine little mini trawler with it.

Fern Ridge photos actually sailing taken by John

Thanks John!

Another light wind day on the water

SO I hauled the boat down to fern Ridge reservoir in Eugene Oregon.  John Khonnen was nice enough to meet me there and hang out.  He keeps his Old Shoe in a slip there.

It was a light wind day again.  I let the whole 120ft2 fly unlike at Hagg lake.  I managed @ 3.5mph in what couldn't have been more than 5-6 mph of wind.  The boat heeled no more than 10 degrees with me sitting in the beach chair in my new helm arrangement.

I haven't show photos of it yet, but I rerouted the mainsheet under the boom to another block near the mast, then down through the foredeck to the cam cleat.  I did this because the cleat didn't work properly with the sheet led in from below as shown.  It also gets the mainsheet off the floor of the cabin where it can be stepped on and such at just the worn moment.

This worked pretty well, though when the sheet went slack there were all kinds of new things on the top of the boat to hang up on.  Primarily my sculling oar.  I threw this in the cabin, so it started to hang up on the aft oar rooftop bracket.  More fine tuning needed :-)

The wind was spotty, but I got enough to find that the boat now balances pretty well with how I'm locating my weight.

I was happy to find that I kept up with/stayed ahead of John in his Old shoe.  No racing boat, but John is an experienced sailor who knows what he's doing.

John Khonnen's Old Shoe

Quiet day on the lake.  Good for testing new rigging.

New forward Hem position

So one of the things i've noticed is that I need my weight forward in the cabin to make the boat trim level.  I rigged some quick and dirty rope steering ala Paradox with a few fairleads and a chunk of rope laying around.  I rigged the mainsheet to run along the floor and turn back through a cam cleat block, all so I can sit low and forward comfortably in my little sand chair.  One cushion in the chair puts me just high enough to see well.

Since rigging this I've found that the cleat doesn't hold rigged this way, i need to come in from the top.  I'll put another block forward on the boom and drill a hole for the sheet in the forward end of the cabin to rectify this.  It will have the added benefit of not having the sheet running on the floor the whole length of the cabin where it can get stepped or sat upon.

I'll upload the changes once i get the sheet re routed.  

Finally getting back on the water for the year

So it's been a long wet record breaking nasty winter here in Oregon.  It's been a long time since I've posted because nothing new has really happened for a while.  I got the boat down to a local Messabout with the Oregon Coots a week or so ago.  Dan Rogers was nice enough to send some dry sailing pictures from the gathering.

Hoping to get out on a lake this weekend.  Truck is in the shop getting some transmission work done, hopefully I have it back by Friday :-)
