You are incredible fast!
Looks great… -
As long the thinner uppermast protrudes long enough into the thicker undermast i wont worry so much.
The fiberglass putty seems not elastic enough to stand the flexing of the parts.
for 100% safety i would remove the putty and look if there are any cracks into the uppermast.
After that i would laminate longitudinal rovings above that part. -
Yes i know, i saw it on the picture. But the industries still use the smaller average from the past and do not use the multiplier for todays taller average. When building for yourself you are of course lucky to use the right multiplier for your height...
-
unfortunately a lot of industrial products like kitchen and other furtniture etc seems to be made with that old measurements in mind.
Compared to the 50ies i guess the people today are at least 10-15% taller than in this old standards.
10 years ago i bought a IKEA kitchen and had to put it on a pedestal 12 cm higher to fit me (199 cm) and my wife( 183cm).
Same problems with chairs. When sitting on an average chair i have to put a thick hard pillow underneath or i can cover my ears with my knees. And the table legs are too short either so my knees hit the tabletop.
So if you are not very short take this old books at least with an additional 10%

You are lucky
Unfortunately, the authorities do not want amateur build vehicles on the streets and set high safety criteria for street approval.
May be with a Kit it is a bit easier. Than only the manufacturer of the kit has to do that inspection process and the builder has to show the ready build trailer to the authorities… -
That sounds much easier to build an own trailer than here in Germany.
Here you need an expensive safety report from an engineer. You have to show him the build in different stages so he can inspect all important structures… -
Such a well build cute little trailer!! Do you need to get it certified to use it on public roads in the US?
I wish i would be allowed to move a self build trailer in the public here in the EU…
I had to scale it up for my needs. Me as a 2 meter man i would get claustrophobic in that...

I wish you good success with that electric engine. It sounds very well thought by you.
Yes reading in other Forum the problems that peoples have with their Diesel and their throughulls…
A friend of mine has an electric Torqueedo outbord on his smaller boot. For emergency he has a small 2,5 HP gasoline outbord on board.
But he has only used it twice in 5 Years as he has to motor a longer distance on river Elbe. With more spare batteries for his small torqueedo he would not have to use it. -
i find the idea with the generator nice.
Torqueedo and a Diesel both have pros and cons…
For inshore or Lakes i would definitely go electric. For large rivers or offshore a Diesel or that solution with a generator might be better choice... -
OK, 18mm plus a doubler should be strong…
Edit:
did you compared the cost of a diesel installation with the complete Torqueedo installation incl. batteries and charging equipment?
Almost the same? -
That motor looks quiet nice and compact. But isn´t the mounting flange a little bit small?
Wouldn´t a larger flange distribute the load when hitting an underwater obstacle better? -
You are making good progress.
The endcap seems to be a good idea. Seen it sometimes at workboats that operate slow in shallow waters. I think with an endcap the rudder needs not reach so deep as without… -
Although it is in german i find in that video they show a good method to apply glass and epoxi over head.
You don't necessarily have to understand German to understand the steps of glassing…
the interesting part starts at 8:00-

Yes i think i am only 200cm not 202 anymore.
The disks in the spine get thinner the older i get. Perhaps we just wait a little bit and shrink to fit the smaller boats…-

Yes i wish i would be made a little bit shorter. It is even not easy to get shoes in Size 13.
Only Rubberboots and basketballsneakers…

Thank you, its not so easy when being 202cm tall.
Berth with 220 are more comfortable then…

... Does the #1800 mean 1800 pounds lead ballast? Seems like a lot.
I think thats the downside of shoal draft and high stability.
I assume with a deep keel bulb it could have much less lead. But for shoal waters it is perfect…
Really nice Design. I have some questions. How long are the berths? What do you think about windage? Is freeboard quite high compared to other designs? Could it be scaled proportionally or only stretched lenghtwise to 26 foot?
Thanks in advance… -
Yes , it is more work than most people can imagine to keep a website up to date.
But i will keep on watching your site because i am curious to learn more about this design, its performance and other specs..

I have been designing the Mathew Flinders for myself for more than a decade off and on, long before we did the Mk3's. What I was trying to achieve was to design the ultimate small voyaging boat that could easily be trailed behind a reasonable size vehicle and yet be be capable of crossing any ocean. She had to be built tough and live well for two people with room for a third person. She is not intended to replace the mk3's as they are great boats, but for anyone who wants to go up to the next level.
I went through hundreds of iterations till I finally got it and I am very pleased with final outcome. As you can imagine I am really excited to see her come to life with Jay and Carol.
I started at 22 feet and it finally grew to 23'4" as I massaged the ergonomics. When Jay ordered the boat, I did a lot of thinking about his comfort plus I had some interest from people who are a lot larger than me so at the last minute I scaled her by 5% to give 6'4' headroom with the final length at 24'6". If anyone has to have 6'6" headroom they can raise the cabin sides.
The trailing weight will be around 4000" depending on how they load it
. I am still planning to build the 23'4" version.
One of the things that I worked hard on was the range of stability. She has positive stability to 180 degrees which more than meets the EU ISO rules for ocean sailing. I have attached one of the many stability curves that I made with the red and blue curves showing a best and worst case vertical center of gravity. That is to allow for builders to make their own modifications and still meet the high range of stability. I was also able to calculate the Flicka A well known small cruising boat, @ 20 degrees for comparison.
Beautiful design!
Reminds me a bit of some keel centerborder that are used here on the german and dutch north sea coast where you have to deal with the shoal waddensea and the deeper but sometimes rough north sea.
Do you intend to put her on your website with some more specs and drawings? Are plans available?
Could be a perfect boat for the time when retirement comes near…-

That looks interesting! Whats the designs name? Mather Flinders? Can´t find anything on B&B website. Do you have more drawings and specs?
-
Acetone and/or brake-cleaner and some papertowel will remove the last oil out of the wood...
-
i simply would play with the sheets so that you get the feeling for the right position in that the sails got the most bite and speed...
-
There are a lot of options... sliding or folding
I think they are available on your side of the big pond too...

Hello Peter, your boat would be perfect for our waters here in the waddensea and the German bight. May be it would need all ballast as deep down as possible.
Unfortunately the order situation in my job is quite weak the last 2 years. So i wait for better times to start building my PS 26...
Enjoy your boat Peter!
