  1. Somethink does not add up. On the side view as well as the photos of the actual boat, the planking reaches the rudders and at that junction the stern appears vertical. On the top view plans though, it is clear that the stern is never vertical. Unless the side planks reach the outside of the rudders vertical but the planking inbetween the two rudders is at a different level and sloped. The side planks seem to indeed stop at the rudders.

     

    Apologies if I am over analysing this, I tend to really over engineer and over loft my hulls! 

  2. Thanks Michael, blocks it is then. The end is so close that I am starting to become impatient! To feel like a child is very rare in our ages but it does happen...

     

    Some more pictures to explain the progress. I am not sure if they help because my camera is terrible, the boat large and there are ropes everywhere. Anyway, here it goes

     

    The two dots are where the sheets will land, the inner for the staysail (inner jib) the other for the flying jib (mid jib). They will not rub.

    Michael, this is the knot you mentioned, no shackle needed

    However, there are more ropes. The backstays land on deck and need to be clear of other ropes. The highfield levers actually have quite a travel and also need to clear sheets and cleats. This is the optimal position

    and we are not done yet. There will be a rail, the aft most pole will be round about there and the 2 ropes through the pole will meet the deck somewhere close to the lever, these ropes need to stay clear away of everything else.

    I need a leap of faith I think and start drilling.

     

    Michael (and everyone else), common blocks will do to guide the sheets when they meet the deck or do I need to make some special sheaves/blocks?

  3. I think it is time for another post. Michael and Mark, again many thanks for your comments. 

     

    I ve spent some time thinking about things, searching the net and reading. When I started building this boat, I wanted to make it as complex as I could, so I could learn. But it is still a small 7 m boat so space is very limited.

     

    Regarding the main sail, I did not make it very well thus the sag. Lifting the gaff does not correct it, it is not square enough. Now, the lacing, this is a misunderstanding from my side. I was not aware that it is kind of either or, outhaul or laced. I am now committed because the sail is full of holes and the boom full of hardware. I ll just pretend that the boat was built to allow the captain to use both ways and that the mainsail has had so much use that has stretched and needs changing. The sails will be furled either way. 

     

    Regarding the rest

     

    1. Cleats will be moved to the outside of the coaming, with one cleat added to the side of the cabin

    2. The outer jib sheet will course on the outside of the shrouds. Indeed this sail is set very loose so the sheet will not rub on anything.

    3. Mark you are very right, Tom Cunliffe I thinks calls blocks on clews "widow makers". Still, looking on photos, many large sail boats use them. In all honesty however, I think for this size boat a simple sheet with no blocks at all should be enough. 

    4. On the forestay (inner jib) I will reduce the power of the blocks, a 1:1 system should be enough

     

    I played around on the boat, trying to arrange the eyes and sheets so that they don't rub. I think it will work but at the stern, everything will be very camped, mainly due to the highfield levers that take on a lot of space and need to move without catching.

     

    I tried to tape things and have a complete rigging before I do anything irreversible but it is impossible as strong tape will lift the varnish and low tuck tape cannot hold thing firmly. So I will need to drill and install a few things. I think I will start with the eyes for the sheets of the 3 foresails and also I ll install the cleats.

     

    In summary, could I ask for your advice on the following:

     

    1. Is it ok if the flying jib (the middle jib) is sheeted straight without any blocks/purchases?

    2. When the sheets reach the deck, do they need to go through a block/sheave or is a simple brass ring/tube like bellow adequate?

  4. Bob, it will be interesting to see how many coats you ll need to cover the grey primer. Hand brushing it took me a dozen or so

     

    Regarding marking the waterline, this is the method I used. Advantage that you can just wipe it clean and start over.

  5. I always seal the wood before painting, it leaves a very smooth surface, I do not like to paint raw wood. I often use primer, to improve adhesion but mainly to have a uniform colour as a base and reduce the number of coats of paint needed

    I ve used automotive primers in the past and they are not very good for modelling. They spray very thick, take a long time to cure and are smelly. For a long time now I ve been using Humbrol primers that come in red, white and grey, the latter I find is the most useful. They are expensive but very nice-no nasty smells. It leaves the surface smooth but a quick pass with 400 grit could be done.

    My experience is that trying to fill imperfections with primer will not work, I remember spraying layer after layer of thick automotive primer and sanding in between, still the imperfections were visible. Really the surface needs to be prepared before the primer goes on

    I have preferred to have my mainsail on my sailboat loose footed and it allows for a nice shape.

    Dear both

     

    I am really very grateful for your help. Now, I need some time to digest your advice and explanations. 

    One way or another we ll get this boat rigged!

  7. Rod's advice above is good. If you look into my Deben log, you ll see all these steps-I hand brushed though.

    I have the same issue with the raised edges. I just live with it. Apparently it is possible to wet sand the paint with 2000 grit or similar to get rid of these edges but it is too terrifying to do on a finished hull. I think this is something I should experiment with.

    One think that needs attention, the paint will find its way to even the tiniest of creases. If you suspect the masking tape is not firmly stuck to the hull, start over. Also remember, any imperfection after painting will be much more visible.

  8. Well, the end is very near but I am struggling with the rigging and I badly need some advice! I will try and explain as best as I can and have taken a few pictures but please bare with me, the boat is large and my photo skills bad so if further pictures are needed to explain the situation please just ask.

     

    First of all I laced the boom

    I also made a brass pulley to re route the backstays from vertical to horizontal. These are offset inwards to follow the course of the backstays to the mast. There will be quite a lot of tension so I ll use screws to secure to the deck

    I took out the rudder I ve made a very long time ago, it is quite huge! It is painted with Valejo acrylics and satin and matt polyurethane varnish, no brush marks at all! Modern acrylics are amazing.

    Now, to get to the problems

     

    1. I have very little space for cleats, I need at least three on each side. Is the position of the cleats on the coaming acceptable? If not I could make some round bases attached to the outside of the coamings to screw the cleats on but the coamings are very thick, as thick as the cleats.

    20200614_162453.thumb.jpg.14b7522cfa246ec63495017d68ec64f1.jpg

    The next questions are about the sheets of the three fore sails, the top jib, the flying jib and the staysail.

     

    2. The only way the sheet from the topjib will not rub and catch on anything is to go in between the shrouds that go to mid mast and the shroud that goes to the top of the mast. The sheet then will go through an eye on the deck and then to a cleat aft. Is this ok?

    20200614_162607.thumb.jpg.eebdbdde332a27978b5c5ca3b36de7f4.jpg

    3. The flying jib will have a single block on the clew, one end of the sheet will go to the deck. However, the sheet, in order to clear other ropes, has to go to an eye or block on the cabin top and then to a cleat aft, next to the companionway. I ve never seen a jib sheet going to the cabin top, is this acceptable?

    20200614_162806.thumb.jpg.1d074ecebbb46e2531d4c31ef8451302.jpg

    4. It seems that the staysail sheet is the easiest one. The books say that this is a powerful sail so two blocks will be needed to tension it, the sheet going aft to a cleat. How do people feel about this?

    20200614_163135.thumb.jpg.866fcf29ae7a9de46de3b4faead8de55.jpg

     

    The cleat that is closest to the bow in this proposed arrangement will be used for the mainsail sheet.

     

    Very many questions I know, I hope I ve explained adequately, any advice will be greatly appreciated!
