Notes from the designer:
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.
