Wolf your boat is a magnificant design. No one in their right mind would say otherwise. Both a gas operated semi auto 30.06 and a muzzleloader bring down deer. To an collector/hunter both have appeal. The deer is just as dead so he feels the same about both as well. Still, the physics of the ocean and weather remain the same and folks will always strive to find a better solution to deal with it. You are right as regards many production boats but realize they are aimed at a different segment of the boating public then your boat is and was when it was constructed. Compare apples to apples and for the same segment you refer to there are boats still being made which incorporate the genius of subsequent generations. Some are the equal to your vessel and the audience who buys them probably know what a gem you own.
There are alot of boats in this town that are "historically correct" andor are fine examples of an older style of boat.(down to dead eyes and kerosene running lights)but other than looking pretty for the "wooden boat snobs" (the sort of people that would keep a classic car in a garage under a dust cover and only take it out on sunny days) they suck on just about everything across the board. My boat isn't just a "quaint old boat", the designer, builder and every one of it's owners has made improvements for the purpose of functionality and/or performance with out trying to be "historically correct"....in an e-mail to Pat Atkin about what was done, she responded "Oh, you have a "modified Atkin". Even though it might not be as William Atkin had designed it, he would have approved of the alterations.
The Sharps rifles were made in the mid to late 1800s and were known for long distance accuracy.
The rifles used by the Imperial Russian Army (late 1800s)were also known for accuracy.
Not sure exactly what you would compare mine to (am not up on antique rifles) something that is a bit on the heavy side, but solidly constructed and good performer. Some boats may fall under the category of a blunderbuss...both old and new (like the Island Packet)
