I'll stick my neck and and say 'NO'.
You need a long, thin (6' 10") shallow draft(2' 6" ?) boat for the canals.
You need a wide, deep draft and as long as you want, boat for use on the Sea.
One of my sea going boats (Cat A) is 38' long x 23' wide, my other (Cat B ) is 36' long x 14 feet wide & draft is about 5' 6"
You need width for stability, you are not slowly drifting along on flat, still water, with banks only 10 feet away on either side.
I ask again - have you any 'lumpy water' experience, any experience planning cruises that are tidal, where you are maybe making 8-10 knots for 6 hours and then can be going backwards for the next 6 hours. If going 'across' the tide you may be heading directly for you arrival point and find that you are actually 20 miles 'off to the side' at the time you should arrive.
