Things look good. Scribing was the right call. And primer about 3 coats as fast as allowed.

Make sure to finish the transom edge square Dan.

Been waiting on paint, and roaming the marinas of Hatteras, NC, thinking about how to get the most out of the cockpit on the C19. Plans call for station E to be full width and height and makes up the bulkhead at the back of the cockpit, nearly 2.5' forward of the transom.

I will hate to give up this much room in the cockpit, and propose cutting station E to match the forward frames, modify the motorwell sides to closely match a typical frame, and do away with the enclosed structure outlined in the plans. See pic for reference. Not shown is a small step outboard of each motor well side, one side of which will be inline with the motor well side, the other side inline with Frame E, the back two sides will be the transom and the side panel.

7096

It seems to me, as I've read in other threads posing similar questions, ( I think Guy P asked some questions along these lines a while ago), with the frames below the sole unchanged, the frames glassed to the sides, and the motor well sides glassed to the transom, there will be plenty of rigidity in the back of the boat. But please, Jacques or anyone else, tell me if this is a bad idea.

The other option will be to close in the transom, move Frame E, as spec'd, back to about 20" forward of the transom and put a built in fish box in the transom gunnel, and put the engine on a bracket. Jacques strongly recommended against this last year when I started.

Here is some small boat porn that inspires me. This is a Croswait Composite, 20 or 21 I believe, built in Wanchese, NC, with a closed gunnel at the transom and a 150 mounted on a jack plate. Definitely appears to be a strong assembly, and not far from what is in the C19 plans, but I wonder about the effects of a 115 on a jack plate on the C19. Again, please advise...

If you want Mertens to approve of another method; I suggest you draw it up fully. I don't see how an ouboard tray stiffens the transom at the top. An inboard gunwhale or deck, rather to the forward loc of the motorwell achieves that though.

Also, all boats need storage places. I recommend you find a way to store stuff there.

Bit draw it up the way you plan so JM isn't guessing and see what he says.

The designed motorwell dimensions are an industry standard. If you move the motorwell bulkhead and make shorter motorwell, you will not be able to tilt the engine all the way and worse, there will probably not be enough room for the steering and cables.
Don't do that.

The full transom with bracket is possible but I do not recommend it on a boat the size of the C19 because it alters the balance of the boat. However, a very short bracket like the one in the pictures (green boat) would not be too bad.
Do not eliminate the floor frame at E but move the upper part back.

Roger on all of that, Jacques.

Frame E below the floor will remain as designed no matter what.

I’d like to cut out the middle of frame e above the sole, leaving only the sides to look like the rest of the frames.

I’ve got some time to think about it, and will take FG’s advice and draw it out and post a pic.

Just going off your original drawing it seems like you are liable to get boarding seas when coming off the plane without that full height frame there. Those little skiffs show the motor on top of the transom. Would be ok for a flats boat I guess?

It’s a typical configuration around here, Mid Atlantic, US. A variety of 18-20’ center consoles. From across the pond, check out Privateer or Parker boats. I enjoy seeing typically styled boats from NZ, I hope you enjoy the same from here!

I had a 3.5 (11') dinghy with a Suzuki DF20a shortshaft outboard. If I buttoned off fast there would be water over the back. Despite this I was never concerned offshore as it had so much buoyancy. Aside from the double skin design with foam in between there were two moulded in seats at the back. Each one had enough buoyancy to fully support the motor.

Suggest you consider the same. If you must reduce the height of the frame, build it into a seat with sealed buoyancy so no matter what the motor won't go under.
