Hi Brian and SOA,
Great to hear you.
I’ve ended up putting a new aluminium strip over existing screen frame and spray- coated – think it will look good and introduce strength were the bolts had reacted with the ali and made large corrosion points.
Thought I was first one to remove keels and replace the gaskets and you beat me to it by quite a few years. Pleased I did it now they are back on – well, another 61 bolts to go and then the sealant etc.
Also replaced the seacocks like you as were leaking but went with a mix of TruDesign and Marelon. Still not sure whether I should have gone for bronze in the engine compartment – time to change as they are sitting loose waiting for another hull coat of Interprotect. Still got to tackle mast and think Martin changed tanks as they look new. I’ve noticed there is a kind of fibreglass aggregator of side-deck drains moulded into hull sitting below waterline with no seacocks – so probably need to resolve before engine goes back.
Once the keels are back on properly, planning to drop rudder as needs repair – why is it I can’t see a sacrificial anode on prop btw? and then need to rewire. If I can get Tarry back in the water in 2023 basically seaworthy then could tackle masts during winter lay-up.
Anyway, hope you had a good Christmas and see you at Feb rally.
Happy New Year everybody.
John
PS: Brian, your email seems to be bouncing – might just be a personal dislike of my email server.
Hi Brian,
Ha ha, yes, I got a few funny comments when I removed the keels and, as you say, they are incredibly solid. The inside keel walls weren’t a pretty sight. I noticed hairline cracks in baffles where joined keel wall and the port front keel section was cracked on the inside. Tipped keel on its end, ground it out and filled with liquid epoxy and left to dry. Then repainted with an epoxy paint for water tanks (see attached). Martin remembers an argument with a pilot vessel (?) which he thinks may have been the cause. Like you, I have 60 keel bolts on one side and 61 on the other. They are at distances of between 3” and 5” and often buried in bulkheads, stringers etc. – such a joy getting to them.
You are making me wonder as I have the windscreen off (one side repaired) whether I should go the hassle of a Halberg type screen before I get new hood made – just aware it adds another delay :-/
Thanks for advice on prop anode – think I need to revisit the wiring around the prop to see where I’m at – definitely one in the re-wiring section of work.
Best Regards
John
Hi Brian,
Don’t think the bilge keels are 1” thick – will have a look next time, my guess is about ½” to ¾” depending on where you measured it – bit like the hull, variable thickness.
Re the windscreen: see attached from a HR31 – a bit like that? I’m thinking I probably put the new acrylic screen on and have a think, as it sounds like quite a project (with associated expense) along with strengthening for the traveller etc. as I actually do like the curve of the screen, but then would probably need to move to glass if I’m to avoid crazing etc. Hadn’t appreciated that until you said and can see from looking online it is a problem. Wondering whether I could get a rigid frame made first that fits, without flexing, and then take it to a glass specialist. Perhaps have to let the rough weather mini-dog house go.
Fantastic bunch of photo’s btw – have a close-up of Rouselle sitting on the sand on my other screen as I type – have been comparing the HR31 windscreen with hers.
Happy New Year – hope you get a chance for some fine sailing.
John

Hi John,
Rouselle was number 100 and she was a Mk 4 design which was the latest I think. She had the latest rudder section which was bigger than the earlier ones but I increased it further downwards by 4" aft to increase the sailing capabilities. I'll send you a photo of her showing the outline. I was interested to hear that you had baffles in your bilge keels as Rouselle's keels were one inch thick which really didn't need them as they were incredible strong as it was. I put a one and a half inch pad on the bottom of each keel made of oak and glassed on that was to reduce the height of the keels off the ground when she was balanced on the main centre keel. Being on a drying mooring meant that when the tide came in the boat would crash over to each side as the original height off the deck was about 5 inches. The pad and the fibre glass amounted to two inches deep and reduced the crash to a roll which was acceptable.
You mention a small dog house instead of a full windscreen. I have looked into that as well and there is a ketch of slightly longer than the Seadog, can't remember the name but it has a small dog house and screen which look OK. The problem with the Seadog is that the angle of the screen and the shape of the roof part has to be dead right to look right but yes it would make a huge improvement. I have seen one on a Centaur and that was about the same shape as would be required on the Seadog. The side panel needs to come back to about five inches infront of the winch to look right. I made cut-outs of the shape and found that the height of the unit needed to be no higher than the present canopy, which was too low to stand up when at the wheel and to get around that it would need a hatch way of some sort. Because of this I didn't proceed with it but I think it could be done with a bit of thought. The other point was that with our increasingly hot summers we really need to dispense with the roof and that is where the present rolled up canopy scours
However for winter winter sailing it would be very good. There is a Super Seadog which is 32ft long and made of wood which has a wooden doghouse. I saw one in the Scillies one year and another in SW Ireland. They were designed and built by Reg Freeman but I haven't seen any more. I have a photo of one of them but where it is I don't know but I have a look and see if I can find it
Sorry hunted high and low but can't locate it under my normal system. I have about 4000photos but it's not under anything catalogued.
Happy New Year and may all the winds in 2023 be behind you
Brian

Hi Brian,
What hull No was Rouselle? Tarry is 47 I think. Just wondering whether baffles were a later addition. Problem with the bilge keels is they are slightly proud and higher risk for a prang – perfect for the odd obstruction in a harbour – does make you wonder whether the HM was taking something.
The windscreen amend sounds like a professional install as I think (not sure) the whole cabin raised section (incorporates cowling, hatch etc.) is one piece and as you say, in order not to look amateur / bodge-it, would have to be done well. So while you are there I wonder whether a small dog house could be incorporated for structural rigidity / hardiness in rough weather (see Halberg(?) example attached – mini version of that) without ruining the looks and then a mainsheet traveller forward of the windscreen (find myself occasionally getting caught in mainsheet hanging of mizzen post in snug cockpit) also better when tacking (?). Then re-do the hood off the back of the dog house which wouldn’t need a gap for mainsheet and could go aft of mizzen post – sounds ambitious but once you go down the road of changing the windscreen you might as well incorporate other amends. Thoughts welcome. Of course means its in the yard for even longer.
Yes, have really enjoyed the work – I’m about 1 ½ hrs away so go down for a day and a half and, whilst probably not the most accomplished practical person, can just take it slow, possibly a little on the obsessional side.
Happy New Year
John

Hi John,
Strangely enough ours did not have any baffles just one inch thick around with no cracks. One of the reasons apart from the fresh water for doing the keels was the fact that I hit a rock on the port side bilge keel at 6 knots when going into Baltimore harbour SW Ireland. I reported it to the Harbour master there and he said" Oh that one everybody hits that. We have thought of putting a buoy on it but have just not got round to it yet." There was a slice of gel coat that had come off but that was the only damage. Had we hit it square on I think it must have cracked but the missing gel coat suggests that we had hit it with a glancing blow and were lucky.
I realize that the windscreen change would be more work but you love a challenge John. If that moulding was made in two halves i.e. front and back with a gap in the middle you could remove the outer flange and straighten out the bend up against the inner flange, and fill the gaps either side with fibreglass and gel coat. It's something that needs to look right and not a bodged job, which is just up your street!
The trouble with Seadog windscreens is that as soon as the panel is bent it causes a stress fracture that appears in the screw holes first and then splits right across the screen. If the panel is bent under heat you do not get stress fractures but it's almost impossible to heat the whole side panel together. I did it once with two of us using hot air guns on low power and that screen did last a lot longer, about 15 years but it was a tricky job. I suppose the answer would be to remove the entire moulding and start again from, the deck up. Too much work for a weekend John.
From the workload you have on Tarry I'm getting the opinion that you like doing what you are otherwise you would not take it on. I used to find that sort of work very enjoyable as you had an end result which you were happy with. I think If I was doing that windscreen job, I'd remove the whole moulding and fit a timber plinth for a flat screen panel system above. When completed the plinth could be oil varnished or painted pale duck egg blue. It would all depend on whether the original moulding is removable or part of the deck moulding. If it's part of the original moulding you could not do that as the flat base gap would be too wide to cover and it wouldn't look right and unless it was done by a Shipwright I think it would spoil the boat.
Have fun
Brian
