Colin,

Sanding epoxy is not much fun, but you can get rid of the majority of the lumps, bumps and dribbles by using a sharp scraper (I favour the triangular ones you can get from paint shops...

Colin,

She looks very neat and clean to my eyes, especially as you are working under such difficult conditions.

As for the gunwales, what you have done will be fine - both structurally and...

The mast I made for the Micro that I built in 2001/2002 was a hollow "bird's mouth" mast to the same external dimensions as the plan. It turned out to be relatively easy to handle (or so I thought)...

Thanks, Mike. The credit for the video goes to the three previously mentioned gentlemen.

Your trim comment is perceptive and interesting. Periwinkle is sensitive to weight in the bow (as I...

Back when Mike first started this thread, I mentioned how similar to Cocquina my Perwinkle design worked out to be in layout and rig. I have to emphasise once again that she was not copied from...

rwatson,

Yes, correct again - thanks for pointing that out.

If you are interested in some of the performance-calculation data and background for Three Brothers, there is a long entry under...

Thanks for the mention, Ian.

rwatson,
you are correct about Three Brothers being quite skinny, as she is designed to be efficient and smooth-running in a steep chop. You will note that she has...

Firstly, I'm very happy to report that recently a number of Flints have been built, or have had successful hull glue-ups, and it appears that my supposition that the cracking problems were due to...

I'm not sure about whether she would be a suitable size for you, but Periwinkle is worth a look.

Colin,

Thanks for posting the pictures, and thanks also for the kind words about the plans.

It looks as though you are doing a first-class job, and thoroughly endorse your comments about the...

Al,

I was concerned about the complexity of the Chinese Lugsail (a.k.a. "Junk rig"), but the number of people who advocated its use (people with experience) made me research it further, and...

Al,

I've been using lazy jacks ever since I rigged my boat with a Chinese Lugsail back in about 1983. I agree with your comments completely.

Richard,

I work on getting adequate rocker so that the ends are just at, or slightly above, the waterline - but make sure that there is plenty of lateral plane at the bow (sharp, fine entry) and...

Due to a call received from a customer in New Zealand, I thought I'd reiterate a warning regarding plywood quality.

In the instruction manual which I send out with Flint plans, I make specific...

Hey Al,

Use a Rolling Hitch, and you will have no problems.

Ross

The convention came about because bits in boats bend and twist over their length, and "2 inches wide x 4 inches high" in one part of the boat may well turn into "2 inches high x 4 inches wide" in...

Mike,

I've only had a very brief look at the postings, and haven't read everything that you and Richard have said, so I may have missed something.

However, normally S means "sided' or "sided...

What I should say is that I did not mean to criticise "Seagull" as a design - it is just that she wasn't suited to the choppy conditions this guy was operating in - I think she would be fine on flat...

Richard,

"Flint" is very deep and fine in the V-sections for'ard, flattening to a moderate V in the middle and aft sections

Magd,

I've included a suggested nesting diagram on the expansion sheet. Read this at the same time as looking at the nesting sheet for the standard boat.

My belief is that whereas the standard...

Al,

Judging by his silence, I think he is still looking for the elastic garter. I'm just worried that he has been offended...

Richard,

All you have to do is draw the original on an elastic garter, and them stretch it - if you are already warped, the transom angle should be no problem....:rolleyes:

Folks,

Here is the text of a post I put on the "Seagull Vs MSD" thread on the "Plans and Designs" section, in answer to a comment made by a member. It has relevance on this thread: -

Hey Al,
...

Hey Al,

Thanks very much for the kind comments you made (I'll send you the money next week), especially about the website and plans.

Magd will be the first one to try the 17.5ft stretch that I...

PAR,

I think you are right, although there are some rig/hull configurations (particularly small boats with lateral plane concentrated) which make it virtually impossible. On the other hand, there...

Here is a link to a YouTube video which I shot yesterday while carrying out a
test sail on Lake Wivenhoe. The boat is a Micro on which I have been performing
some maintenance. I built her back in...

Hey Richard,

You obviously haven't seen the state of my building shed or my office - the only things which are neat are the finished boats - the rest is a shameful mess. But, it is said that...

I use cable ties all the time when building stitch-and-glue. My preferred method is to run 'tack-welds' of thickened epoxy BETWEEN the ties, and the next day the ties can be removed easily, as they...

What should have mentioned in the previous post was that you don't have to use 2400 x 1200. By that I mean that I've drawn the plans so that you can get the panels out of sheets with a minimum size...

The choice of ply for a boat like this depends more on the quality of the ply construction rather than its weight and/or timber species. The twist in the bottom panels up for'ard is pretty serious,...

Thank-you, Mike.

Yes, Periwinkle sails beautifully, but (as predicted at pre-design time) the balanced lug cat-ketch (Periauger) rig is not the fastest way to get to the up-wind mark! However, as...

Dear Mike,

I've used caster-equipped strong-backs on a number of occasions, but in each instance, the casters were used only to move the strongback to a position. From there, the whole thing was...

PAR, AJ and Rob,

Thank-you for the comments. After the light-wind launching, Periwinkle was towed to Caloundra and spent her second day of sailing in fairly heavy winds, on salt water. This gave...

Green Ginger and PAR,

Thanks very much for the comments. There were a number of elements which I was concerned about (all of them?!), with the most particular ones being ability to hold up the...

Ahh, Child's Play..... She is a real favourite of mine, and is on the list to be drawn as a set of detailed plans. But, before then, I have to finish off First Mate, Periwinkle, Three Brothers, Test...

Fair Dink,

I'm flat out at the moment finishing Periwinkle, First Mate, and holding down a part-time job to make ends meet. (the message from that is - don't be a boatbuilder if you want to...

Fair Dink,

Thanks very much for the encouraging comments. Yes, she is getting close to the launching day, and I'm becoming nervous (always do before a launching when the boat has been built for...

I use a 17cfm, three-cylinder compressor to power a range of different guns. The ones I use most often (almost exclusively) are Star gravity-fed HVLP guns with 1.3mm and 1.7mm tips. The other...

Regarding the latest photos of Periwinkle on the website ( www.baysidewoodenboats.com.au ), the mocked-up breakwater on the fore deck will most likely be ommitted from the proper deck when it goes on...

The Periwinkle photo up-dates on the website may have appeared to be going slowly, but that is because there is not much to photograph when sanding, painting, sanding, painting, sanding, painting,...

AJ,

The devil, as always, is in the detail. I think that although the hull modelling is ultimately the most important part of the equation, it seems to take the shortest time in the design...

I've been thinking about what m2c1Iw (Mike) mentioned in a posting further back in the thread, about introductory texts on boat design. At the time I gave a reply which didn't contain much...

I lie awake at night thinking about things I should have done differently - on building projects as well as designs. The demons seem to be at their worst at about 2am...

The thing that I try to...

Thanks very much indeed, Mik. I'm very grateful for what you have said.

Ross

Mik,

I don't know whether you are pulling my leg or not :? , but I am grateful for your kind words.

The process of design has got me well and truely puzzled, and I find that the more I learn,...

Yep, I should have mentioned "Skene's Elements of Yacht Design", but not the Francis Kinney edition. I've got Edition 6 (Skene) and edition 8 (Kinney),but the Skene original is the only one I...

Mike,

Sorry for the delay in replying - beyond my control, I'm afraid, due to commitments elsewhere.

The matter of plank width is a difficult one for which to find a perfect solution. I would...

Mike,

The matter of hull-form in the forrard sections is one which I have been pondering for a very, very long time. I have to admit that I'm still working largely according to gut-feeling, but I...

Arbordg,

My use of glass or polyester would normally be for abrasion resistance and would therefore be placed on the outer surface. The only thing that I would consider using Kevlar for would be...

Arbordg,

No, I'm not advocating the use of glass. If someone wants to improve the strength and stiffness of the bottom of their boat, I believe that it is far better to increase the thickness of...
