Thread: Iain Oughtred designed Gannet Build

Denman now is importing Brynzeel from Holland instead of Joubert but the quality is very high.

Yes that is correct. The Bruynzeel is a higher quality, still carries Lloyd's Register Certification of compliance to BS1088-1:2003 plus it carries a 10 year structural guarantee.

Really lovely stuff. More expensive for us to buy but with the value of the AUD/Euro being in our favour, we have kept the price the same as Joubert.


BS1088 is a British standard, and as such, means nothing if sold outside of Britain, and furthermore doesn't need to go there to get stamped. Buying a 1088 stamped ply is a matter of assessing the individual quality of each sheet, and getting the malay marine may not be worse, and indeed may be better..

I would disagree with this statement. BS1088-1:2003 is indeed a current British Standard but many companies throughout Europe and the rest of the world make marine plywood to this standard. The standard definitely does mean something outside of Britain. If a company "stamps" their plywood with BS1088 then they are making a claim that their product complies with the requirements of the standard. Unfortunately, the standard allows manufacturers to self certify their product but strongly recommends independent, third party certification by someone like Lloyd's Register.

So how does this apply in Australia? Pretty simply.

Under Australian Consumer Law, Australian businesses must provide consumers with guarantees for consumer goods and services they sell.

Consumers have the right to ask for a repair, replacement or refund if the goods sold by a business are:

- faulty
- unsafe
- look unacceptable, and
- do not do what they are supposed to do

Consumers also have this right if goods sold to them do not:

- fit the purpose discussed with them
- match the description provided
- match the sample or demonstration model provided
- have the extra qualities or performance promised before the sale

It is also unlawful for businesses to make false or misleading representations about goods or services in promotions or advertising.

Further information is here

So when a plywood re-seller claims to be selling BS1088 marine plywood in Australia, they have an obligation to the consumer under Australian law to ensure that the product they sell indeed meets the standard. I would suggest that if a person buying so called "BS1088" ply becomes aware that the ply they have purchased is not standard compliant then they could ask for a refund or replacement.

Sorry for the rant but I get so many phone calls and emails from people who have purchased non-standard ply from unscrupulous vendors and some of the stories (like the one above about the CS17) are just heartbreaking.

Hi Cameron,

Lovely to hear from you. Miss Mouse came up a treat in our pictures. Yes indeed like an Oughtred build the progress on the film has been slower than expected. Largely because we missed the northern summer last year for a variety of reasons, but we've been away shooting for most of the last six weeks. So now we have vision from Sydney, Hobart, up and down the Maine coast and various locations in the UK including Edinburgh, Anstruther, Brighton, Oxfordshire and of course the Isle of Skye. All up some 50 hours of vision that we now compress into a 50 minute film. That is my task between now and February unless boring things like work get in the way. It is my intention to have the Shearwater completed in the same time frame with a view to launching her in Hobart at the Festival. One of the joys of the project has been the opportunity to work with Iain and speak with like minded folk all over the world, appreciating all the while how something as simple as little wooden boats can change people's lives for the better. My own included!

Best,

Andy Mac

Well best laid plans and all that! As you will see it has now been over two months since my last post but with a bit of luck things are beginning to move again.


The moulds have now all been cut and fixed to the build frame. In the end after trying to track down some packing sheets, or similar, with no real luck (or at least with anything that was close to flat) I opted for 18mm mdf. Not the cheapest but will hopefully make life easier moving forward. One mould was made in two halves (to make the most of the sheets) and another was cut out of some recycled ply that I managed to get hold of, that was being thrown out. Of course the ply was being thrown out the day after I had finished cutting all but one of the moulds......................

Mould Mark Out.jpgMoulds Set Up 1.jpgMoulds Set Up 2.jpgMoulds Set Up 3.jpg


Like a lot of people I have a tool wish list that is quite long, but for what we don't have improvisation plays a big part. A band-saw is very high up my wish list but space and money are currently not onside for this. So in order to cut the laminates for the stems I temporarily glued a number of 1” thick pieces of spotted gum together, squared two sides of this glued up piece, and then slowly cut 4.5mm thick laminates on my Triton 2000. This method although a little time consuming worked well and seemed to be relatively safe. I am sure there may be another method that I could have used but this allowed me to have minimal wastage. This was made more so as I also glued a piece of mdf to the stack on the fence side.

Stem Veneers Temporary Glue Up.jpgCutting Stem Laminates.jpg


I built the jig for the stem out of some leftover ply from my router table. I first glued the inner stem and when it was dry, cleaned it up and shaped the forward face to that match the pattern on the construction plans. I then laminated the outer stem around the shaped inner stem. The outer stem has since been cleaned up and is now stored under our spare bed until needed (couldn't find anywhere else out of the way that I could keep it flat).

Inner Stem Lamination.jpgDry Fit Outer Stem.jpg



I must admit the stem caused me days, or was it weeks, of procrastinating. On the Mould Plans it shows what seemed to me to be strange fairing lines for the stem which didn't seem to add up with the details shown on the Stem Plans. The Stem Plans show a 'normal' equal width stem, however, some faint lines on the Mould Plans indicated the stem should be faired to widths that were wider than the stems I had just laminated.......................... To top it off on the Construction Plan it says to refer to sheet 4 for fairing of stem. Sheet 4 is 'Sail Plan II' and contains nothing related to the stem. Eventually after scanning the internet for some answers I came across someone else who had had the same dilemma with an Oughtred Fulmar. The Fulmar is same design as the Gannet but is the bigger version. Because the bow of these boats have a lot of flare they have to have wedge shaped blocks glued to the sides of the stems which are then faired down to the lines I found on the Mould Plans. I could have kicked myself as there is a note on the Construction Plans that states the stem width is increased with wedge shape blocks, it is just not mentioned on either the Stem Plans or near the stem fairing lines. Anyway I have now glued blocks to the side of the inner stem and I will be shaping these shortly


Lastly, the transom. As mentioned before I am using spotted gum.....argggggghhhhhhhhh..........tear out, tear out, tear out, tear out....................... After trying a number of jointing methods (jointer and router with straight edge) I finally resorted to jointing by hand. With the previous two methods I either couldn't get the edges straight enough for my liking or I kept having the grain tear out. Even jointing using a 50 degree blade in my Veritas Bevel Up Jointer I was still getting tear out, although minimal. Finally after filling a 20L bucket with shavings I finally had two a joints I was happy with and promptly jointed these using Titebond III. The boards had a little warp to them and I did my best to straighten these during the glue up. Once dried I flattened the whole panel to an acceptable flatness using my belt sander as I only had a few millimetres of thickness to play with and didn't want to risk more tear out. Once I have cut the transom to shape I will finish flattening it using a combination of belt sander, orbital sander and scrapers.

Ok so this has been a fairly long winded post. I will do my best to post more frequently as the build progresses but once again 'best laid plans................”

Hi Andy


Wow that is a very impressive boat you are building there. I look forward to seeing the documentary. As you will see by the gap between my posts things for me are also taking longer than hoped but a very rewarding experience none the less. The way I am currently going your documentary will be out long before I am finished the Gannet.

I have both Iain's Clinker Plywood Manual and John Brook's Glued Lapstrake Wooden Boats, both of which I find invaluable.



I will hopefully be contacting Denman Marine soon to put in a plywood order but want to time it right as I have limited workspace.


Regards
Brett

I just ordered the plans for the Gannet and plan to start building by the end of the year, so I really appreciate the comments on this thread. This will be my second glued lapstrake (clinker) project, having just completed John Brook's Compass Harbor Pram. It was fairly simple and a good first boat to learn from.

I plan to plank the Gannet with 6mm Sapele plywood. It's more expensive that Okoume (Gaboon) here in the States, but I've been told that it is more rot resistant that Okoume, and is what I used on the CHP. I was very happy with it. Any thoughts? Is anybody fiber-glassing the bottom or just painting? (I just painted the CHP). Is anybody "down under" using Sapele?

Nothing like a deadline to keep things moving! The Shearwater is booked for Hobart so we've had to get a wriggle on with the build. The film about Iain will still be work in progress but there will be a trailer of 6-7mins to take a peek at. There's a little article about it in the upcoming issue of AAB.

Anyway, back to the varnishing...

Fair winds,

Andy Mac

Dear Brett

How is the Gannet going?
I got out of the way of checking this site.
My boat has had its first birthday. I still enjoy sailing it when I can. In November spoke to the Qld Wooden Boat Assoc about the project.

I'll try to attach a few photos.
