depending on the original hull you copy the size at 1:16 would vary greatly, at a guess 15-17 inches would prob be a good guess in size... but 1:16 is one of those awkward sizes personally i would go right for the 1:6 action man scale, full size servos large battery, loads of room fir true scale detail and men readily available to row it!....
@ 1;6th scale the boat would be about 36-48" long a really nice size boat to work on an run at the lake IMO.
As for copying mine, i would avoid it, there were a lot of mistakes i made which i needed to fix through out the build, and overall its a nice boat but by far its snot even close to my best work in comparison to other builds.... coping it would only serve to make a working rowing boat, given that my row boat is 1:24 scale its great for what it is at that size... but 1:16 wouldn't give you and extra grace in building to scale, 1:12 would be the smallest i would recommend for others to have a go, but i will always stand by my thoughts that 1:6th is the way this boat should be built, hence why i have another rowing controller ready and waiting for the right hull!
At the end of the day its a unique boat no matter how you build it, but when you build a rowing boat given how sparse they truly are then it comes down to build style and personality which will make or break your boat...
