I have written and asked about access to the after section of the platform since I joined this group a year ago after I bought my newer boat.
This all had to do with mounting my Surfjet on the rear, as well as how to reinforce davits etc.
To summarize, I spent 3-4 hours last year by reaching through the access port on starboard, to line up 4 nuts on bolts that were about 25" inside the platform. I used an extension piece of wood with brackets bolted onto my socket wrench so that I would not lose them in the bilge of the platform, as well as a 4 foot piece of rope leading to a cleat.
Carver does not gelcoat the inside of the platform. No body does. My arm eventually looked like a meat grinder had hit it, but I got the job done, strictly by feel of the wrench and nut contacting the protruding bolt.

Any way, that is old news.
The good news I learned this weekend was that behind the bed, on port, there is what looked like a pull tab on the headboard. I followed the design around the cabin and realized that the left side bolster / Valance under the side window has 6 small Phillips head screws (which are murder to get to, as nobody has a tool that small. Then the rear bolster comes out , by slowly peeling it off the velcro, and finally the 2x3 foot panel will pull out as well,
Now the back is open, you can access the cable locker, the auxiliary fuel tank, which I didn't know I had, and the exhausts.
Oh, and my favourite wrench did fall off last year and I really missed that size 1/4. and 3/8 ratchet. It wasn't the money, but it killed me to know it was sitting there on starboard all year and I COULDNT GET TO IT.
