Our family original 14' 1959 Crestliner has done just that several times . . .
the bow deck is only riveted on. My two younger brothers and I take turns
with "possession" for a few years at a time. My younger brother is an avid flats
fisherman and duck hunter. So when he has the boat, he takes the bow off
and puts on a 12" bow to hold the cleats, handle, etc.
When it is my turn, I undo all his tinkering and adulteration, smooth down his
ugly camo paint and replace the bow deck with rivets and repaint it.
This has been going on for the past 30 to 40 years. LOL so you can only imagine
the HOLES this thing has in it. (all professionally fixed, I might add).
This is how it looks now . . . .
I want to add the center divider and make new wood seats that fit appropriately.
You can add any configuration to your boat. The design is limited only to your imagination!!!!
Get some .080" or so aluminum sheet, draw on your design, cut out with a jig saw,
smooth down the edges, make whatever curves needed and rivet to your boat.
Rivet in whatever center supports needed. (or wood).
Get some aluminum edge guard (not that automotive plastic stuff) and you are good to go.
that's my plan !!!
Edit: as far as pricing goes, the only cost would be the sheet of aluminum that you
can find at the best price, the edge guard, available on line, and the rivets.
oh, and the two very nautical step plates (from e-bay).
OH, if you want to keep your tiller steer, put some planning into the size of the
"captain's cockpit" and you can still keep your tiller steer.
I just looked at your boat - - - it is a 13' ?? just measure out what you want.
use the "CNC" design technique (Cardboard n Chalk) . . . cut the elements out of
cardboard and tape them in place on your boat, then, with some chalk, draw out
your designs . . . chalk works better than a sharpie marker because you can make
the adjustments as you go along.
To get an idea of the cost, call your local aluminum supplier and see what a sheet of
36" x 60" x .080" (or so) would cost. Then, you will even surprise yourself at how you can
modify your open skiff into a vintage looking family cruiser !!!!
The curved vintage looking windshield is another matter altogether.
I am having a hard time finding one here in Florida at a decent price and condition.
I am continually scouring C/L and back yards for an old boat that has one, buy it,
keep the windshield and try to sell the boat for what I paid for it. (dream on, LOL).
But, with a little skill and planning, you can make one out of flat pieces of plexi.
They look good, but is not original to my boat.
