The first week of summer

The summer solstice was just a few days ago and today, after 14 months since the knock down, Ventura sailed once again!

It was a very nice day though I could have used just a touch less wind, but in the end it was just fine.  Trying to get this rig back together and sort out everything is tedious and time consuming.  One really needs to be happy just "messing about" in boats with a trailer sailor because so much time is spent getting the boat to the water and ready to go, then doing the reverse at the end of the day.
Our sail was only about 2 hours, but it was enough time to take the boat thru it's paces.  We raised both main and jib.  We reefed the main.  We tacked.  We jibed.  We docked and we used the motor.  It is all working again.  The only thing we didn't really do was anchor.
I have along "to do list" after the sail.  Mostly things I forgot, some important, some not so much.  I forgot to put on the rigging for the reef point, that was very annoying.  I made it work with spare line onboard, but heavily chastised myself for not thinking it all thru.
The out board was a bit inconsistent as we left the dock and eventually died, but we had decent wind so we just sailed.  On the return I ran it for a while and it eventually evened out and ran the entire time we needed it.  This was the first time it has really run since it was IN the river.  I did maintenance it after it's sinking but hadn't really run it very long since.  I think it will be fine.
In truth my enthusiasm for this kind of boat, this kind of sailing isn't very strong.  I miss my full keeled cruiser on it's mooring.  But I will make due with what I have right now.
It was good to be back on the water and even sailing with in sight of where I took my very cold swim, the one that was almost the last thing I ever did, was fine.   I really only gave it a thought for about 2 seconds, maybe 3.
There is a lot of summer ahead.  Todays sail only cost 10 dollars at the launch ramp.  I have to do quite a few of those to equal the cost of a slip for the summer, so that makes spending the 10 bucks a lot easier.  Let's see what the summer has in store for us.
Fair Winds!
Although I am thinking of having a new mainsail built for Ventura and using her as much as I can I will say that if anybody needs a very, very cheap boat and trailer I am open to selling her.  I have too many boats right now and I really miss sailing my Bristol

sails

I know that there is something elemental missing from these photo's, like water, but one step at a time.  Presenting the Venture 21s.  "S" stands for short rig.
Formerly the staysail, now the jib.  Kinda small but it'll work
The shortened main sail.  Always was short along the foot.
The sail actually has roach to the leech but I don't have the battens in.
Cut and pasted jib, from the first photo into the second and now we
have all working sail up.

It's not a lot of canvas but I ain't racing and at this point in my experience with this boat, I'd rather be under canvased.  (Wink, wink, nod, nod).  I hope to be in the water next week.  Before the equinox would be nice.

My rigging measurements were good

New rigging copper swaged eyes, slathered in lanolin and
covered in heat shrink tubbing.
Workboat handsome, or industrially cute?
I stepped the mast today with the newly made rigging.  All the measures were good.  The turnbuckles were about 60 % open when it was all snugged up.  That should leave some room to take up if and when things stretch out under strain.
It was a breezy day so not only was I wishing that I was launching, but I also had to be careful about raising sails while the boat was on the trailer, which I did to see how things fit.
The small jib which was the staysail is truly small, but, it fits nicely on the forestay.  I have yet to alter the jib and genny to fit the new rig measures.
I also set the main, which was much easier for the topping lift that I added to the boom, but still awkward as the mast is really designed to have the luff, as well as the foot of the mainsail in the groove.  This main has the roping on it to set it this way but lugs have been put along the luff.  I'm not sure why this was done and only realized this now after owning the boat for a year and a half.  Duh!
Anyway, the mainsail's new height is good.  I may end up with a lot of chafe as the leach passes under the back stay and the topping lift.
I took pictures but my phone is having issues sending them to the computer.(piece 'o' shite!)  I'll add them later.
I will say again that it is so much easier to raise this mast now.  I suppose that the 15% of length that is no longer out at the end of it makes a lot of difference.
I'm not sure what is next, maybe launching her and sailing.  There is a thought!  It's been a while.

Jib (staysail) is ready

I had to stitch a new clew onto the staysail that I am using as the jib.  It works pretty well for stronger weather.  I added a patch and then a roped grommet to the clew and we are set to go!
I also moused all the upper rigging points.  So I guess the next thing is to try raising the mast again and seeing how it all worked out!

"New" Standing rigging

My new standing rigging is finished!  After much research, and a bit of stepping back to look at the big picture, I decided to go with the "nico-press" type of fittings because it was inexpensive, I could to the work myself, I didn't need expensive new tools or machines, and I could reuse a bit of the material I already had.  I fully realize that many might be critical of the use of this type of fitting, and I might be to, if I were setting up a boat bound for open water or even strong weather, but in this case the boat is to be used for recreational, fair weather sailing, and having "made" the rig myself, I will be more mindful, and aware of the conditions of both the rig and the weather.
Had I been using this rig a year ago, I might have been more conservative about what I put the boat thru, decided to quit sooner, or not gone out at all, and saved my self the experience of being very, very cold and wet. (on the good side, I now know what that is like.  Ignorance can breed fear, and knowledge allows for better judgement, I hope)
SS thimble, 2-Swaged copper sleeves on lower shrouds
coated with anhydrous lanolin, then covered in shrink wrap tubing
Some info on this rigging technique:
-1x19 S.S. doesn't want to bend the short radius of the thimbles.  It seems that the sharp bend may compromise some of the strength of the rig.
-1x19 S.S. requires 2 copper sleeves, each swaged 3 times along their length.
-I made sure that the sleeves did not actually touch the thimble, or each other.  I did this to promote a full compression of each swage.
-The end of the SS wire stuck out of the lower swage, but was covered by the heat shrink tubing.  Before the tubing was applied the entire fitting was slathered in anhydrous Lanolin for protection.
-I used a swaging tool that uses 2 bolts, tightened down to compress the copper sleeves.  This tool was the least expensive(a priority in this boat), smallest (so that in the future it can be kept on board my larger boat for emergency rigging), and it was simple.
- I checked the swages with a micro meter to see if they fell in the specs that I found on a forum thread about home built airplanes and this type of rigging.  the tool was pretty consistent with the thickness of the finished swage and that dimension collaborated with the aviation specs.

I believe that Brian Toss mentioned that most of the boats he'd seen rigged in this way were in the UK.  He didn't recommend these fittings very highly and seemed to think they were the wrong "tool for the job".  I wouldn't disagree with him ultimately, but, I think that they will serve fine in this application.  Most of the negative comments I found on the forums about pressed copper sleeves seemed to be about the way the finished fitting looked.  I actually like the work boat kind of look they have.  It is even more attractive because the look reflects that I did the work myself.

Using this tool with these parts required really taking my time setting up and making each swage, three for each sleeve, two sleeves for each eye, two eyes per stay, six stays, plus a few practice sleeves.  I have to enjoy each moment of the work or I will rush to be done and botch the job.

Now on to recutting the sails.

Presto! the mast is in one piece again.

Here is the repair of the mast with the pop rivets in.  I found that the epoxy got thick pretty quickly so I worked fast.  I think that with the number of rivets, the epoxy, and the area of the scarf, the mast should be pretty strong.
Looks like I took a Bedazzler to by mast!
 The mast does have some slight twist and bend to it but not so much that I don't think it will work fine.  The sail track lined up just right.  I am hoping that with the rigging I can pull it into as true a shape as is necessary for it to work.  The distortion is only slight.
I had to cut off about an inch of the spreaders because on got smashed on the inboard end.  I don't think that will be a real problem.  As I have been going thru the rigging I think that I can get three of the six pieces of wire rope from what I have.  I think the back stay can become the forestay and the upper shrouds can become the lowers.  All of the wire rigging was cut by the tow company when the recovered the boat.  Kind of seemed like somebody just got a new wire cutter and had to try it out.  Oh well.

Ventura mast repair

As I walked across the street to collect up the fire wood I'd been chopping I looked back and caught sight of Ventura sitting there on her trailer.  I had put some white primer paint over the fiberglass repairs so the big blotchy scars were not so apparent.   I had a flash of the sensation of sailing her and all the kindly attributes I could ascribe her, including my surprise to discover that she was a quick little boat that could move along in the lightest air.  I laughed out loud, giggled really.  How many things that you own actually make you laugh out loud, or even smile each time you see them.  My boats do this for me.
So with renewed energy I set to work on the mast repair.

I had cut and shaped the 2 halves of the 18 inch section of mast that I was using for the scarf repair.  Now that they fit inside the mast snuggly I could start the attachment process.  I decided on a pattern for the fasteners.  Each half of the masts would get a total of 22 rivets, all offset so as not to create weak "perforation in the mast.  I drilled out the holes in the mast to the size of the pop rivets, 3/16 inch.  I then fit the sleeves inside, as snug as I could get them to the inside of the mast  and chose one of the rivet placements for the first self taping sheet metal screw to be placed.  I pre drilled the hole, undersize in the sleeve as it was held in place and then drove in the screw.  This had the affect of drawing the sleeve in tight to the inside of the mast.  This allowed me to then drive in the other fasteners and have the sleeve as tight to the inner wall as possible.

Once I finished attaching both sleeve halves to the bottom section of mast it was time to attach the upper section.  Lining up the two pieces as best I could and using length of scrap metal T track set in the sail track to keep it straight and aligned I then continued the process of driving in screws.  These screws are temporary, holding the sleeves in place until I put in the permanent pop rivets.  Using the screws to pull the inner sleeves tight against the inside of the mast and allowing me to remove them and adjust if needed.  The sheet metal screws are a smaller diameter than the pop rivets so that if a hole from a screw needs to be adjusted, the pop rivet will still be able to do it's job.

Even with only a few screws in I stood the mast up and the scarf felt very strong.  I am probably going to coat the sleeves with a TiteBond epoxy, that is supposed to work on aluminum before I rivet them in place.  I figure that even if the epoxy doesn't bond well, it should work as a bedding between the two surfaces.

Skiffing again!

Working on a project for the skiff.  I'd like to add a rudder to her, so, I tried out this one that I made for a fiberglass dinghy. just to see what it looked like.
rudder from another boat just for size.
 It seems pretty close to being about the right size so I decided to glue up some cedar decking on edge to get the width I want.  I will add some horizontal "straps" to  help the glue hold the rudder together.
reclaimed cedar decking being glued up for a rudder.
I'll have to work on the actual shape of the rudder and I may need to weight it to counter the buoyancy of the cedar.  I am thinking that instead of a typical tiller I will use a fore and aft steering stick so as to make it all less cumbersome.
I am sticking with the Gorilla Glue for the adhesive and the cedar decking is already in use on the boat.  I may offset the cedar with yellow pine cheek blocks, or the luan plywood, but I haven't decided yet.  I'd like the cedar to be varnished.
It was extremely pleasant to be working on this boat again and to be in the shop again.  I hope to get the boat out for a row soon, maybe tomorrow.  After the winter dealing only with the Venture I had forgotten how fond I am of these boats that I made with my own hands.  Makes me kind of wonder why I ever bothered to get another fiberglass boat.

Speaking of the Venture, I found some scrap aluminum in the shop today, some plate, some tube.  I think that it might be usable as the joint for the mast so that I don't have to cut down the mast anymore.  If this works out then I will have only lost a foot of mast height, which may mean that I won't have to recut any of the sails.

clean cut

Today I cut the rough edges off the mast to begin the repair.   I cut out a 4 in section to experiment with how I might make a sleeve/insert.  After cutting a slot on the back side of the mast I realize that I will need to cut down the diameter of the insert quite a bit in order to get it to fit in the old mast.

Cut off ends and a section to experiment with.
 I have done some looking around online to see what others have done and I think I am narrowing down my approach.  Right now I am thinking that I will cut the insert in half, lengthwise in order to make 2 shaped plates that I can then mechanically attach the 2 mast pieces with.  Since I am planing to reduce the rig anyway I can make the insert/plate about 3 feet long, which should give enough area for the scarf, a foot and a half in each section.
Clean cut ends ready to be joined back together.
Now what?
I am sure the most challenging part will be lining it all up so that the sail slugs run clean in the track.

I finally got inside the boat and got out the water that the tow boats bilge pumps didn't pick up, about 12 gallons.  I also put the port sheet winch back together.  Amazingly, I still have all the pieces to it, even after the sinking and 2 days under water!  I also put some plastic and tape over the holes in the deck that will eventually be repaired so as to keep them from allowing more water in the next time it rains.  I have a feeling this boat will forever smell of the Hudson River.
