Hi Brian,
Thank you for this long and interesting mail.
About the difference between JG Meakes and Freeman, I am not sure they are existing. It would have been very hazardous to modify a scantling just like that.
I enclose the Sales brochure from JG Meakes, and as you can see the weight is exactly the same, therefore, the wall thckness of the shell side is the same.
I only could measure the thickness at the location of the toilet Blakes valves.
A long time ago, 1978, my father's Dog "towed" her mooring block during a storm and she finished in the rocks on the coast.
The only damages were some rocks broken, the edges of the bilde keels were damaged, but they did not loose their watertightness, nor induced any damage in way of the fixations.
The hull was just scratched. The other boats having experienced the same accident sunk.
The repair yard had never seen such a heavy construction.
Even the shape of the hull lines of the Dog make it strong, there are no "flat" surfaces (the curve radius is low)
My rope cutter is made of two parts (one fixed one rotating) and acts as scissors.
Concerning bilge keels vs fin keel, my choice woild be again bilge keels. May be it is slower,, but it is really amazing the way that bilge keels reduce the roll.
For sure a bowsprit enhance the perfs, but my limit is financial ...because of the price of the marina. (even if it is cheaper than in England, roughly 1800€ per year, and if your boat stays on the dry, no extra cost, you just pay the lifting)
I started the process of osmosis tretament (gel coat planed) but it was delayed because of Covid, and then I could not sail this summer, and if the situation does not improve, may be she will stay on the hard next summer too.
It is for me the opportunity to make some TLC's.
Right now, I have not the right to go onboard to make some works, because of Covid restrictions (even if I would be alone onboard...but I don't want to get a 135€ fine...)
If some other read that and somebody had the opportunity to measure the hul thickness, it would be instructive.
I hope my "frenglish" is understandable.
Kind regards to all
