    This is a continuation from my other thread. I started over since we moved on from the pilot house topic.

    previous: Helm/pilot house location https://www.boatdesign.net/threads/helm-pilot-house-location.66038/

    So moving on I'm not really worried about visibility, there will be more then enough. As far as the roof goes, it will likely have a curve to it so a 2" foam core is not ideal for that. 3/4" glassed on each side will be more then good enough to walk on when needed. While the core does have some insulating value it's not much, so I'd want an inch or so beyond that.
    I like glass doors, but they are pretty heavy and this is a light weight trailerable boat. So I'm not sure that's a good fit.

    A few more line drawings I did recently. This is more of a stretched out version of the Pawson Hobo 18ft, now 22ft.

    I'm also playing around with the interior. Here's my first thought. We really don't need a dinette so I replaced it with another seating area. I might change my mind later.

    That's it for now. I'll develop the idea a lot more over an extended period. So this thread might be revived on occasion.

    This is the original concept.

    Just an observation re your sketches above - in the side elevation the bow is to the right, but in the plan view the bow appears to be to the left.
    Would it be possible to re-post one of the sketches, so that they are both aligned in the same direction?
    You show a door by the slide out berth in the plan view - but it is not shown in the side elevation.

    Re the side elevation, is the hull shape going to be a tri-cathedral type (re what looks like a shorter outboard tr-hull in the sketch)?
    If it is, what will be your hull construction material?

    Re your slide out double berth, one disadvantage for the person on the aft side is that they have to clamber out over the person on the forward side if they have to get up to visit the loo.

    trailerable-small-houseboat-continued.66135.png Here is the sketches aligned in the same direction with door added and the head moved with a curtain instead of walls. In my RV there is the classic 70's stool/shower/sink fiberglass module and it is a claustrophobic space. In my sailboat there is just a curtain for the Porta-Potti.

    I hadn't gotten far enough in the design to realign everything to be true to form yet. The only reason I did the interior sketch the way I did is because I was working off the original sketch I made while sitting in the boat. So let me try to answer in order. It will be more of a garvey or V hull, not a trihull. I may even decide to go more of a barge style in the end if the math dictates, but I doubt it. Hull construction will likely be CarbonCore PE and vinylester/epoxy resin with various woven and biaxial cloths. possibly some basalt mixed in. It will also have a integral outboard bracket, or euro transom.

    As far as the berths go, I don't have dimensions on it yet, but the cabin is only about 15' x 7'. So no matter which way you arrange it one side will need to be against a wall. Well at least if me and the Mrs. plan on sleeping together. Is it ideal, no, but if I want to stay under the 8.5' towing limit that's what needs to happen.

    Tops, thanks for flipping that. I'll work on it a bit more later. As far as the curtain goes, that's a no go. My wife has IBS, more info then you needed, but it explains why she insists on an enclosed bathroom. The head will have it's own vent fan, and a porthole to help with claustrophobia.

    I'll try to finish up some other ideas and post them soon. This is all still early planning.

    Yes they do. However they also have a huge drawback, height. Your living space starts 2.5-3ft in the air instead of 8" above the keel. This increases your windage and limits storage and towing route options.
    If It were to be used on just a local lake then I'd do a pontoon conversion, but this will be used along the coast of Florida.

    A little diagram for reference of the WC in the RV. Imagine that the red is the pink pre-mold and the top half is a slate gray laminate with aluminum trim. Only light is in the medicine cabinet. Only vent is in the roof. The shower comes off the tap from the basin and drain is in the corner of the foot pan. Stool is foot-flush. There is a curtain that runs out to keep the basin area, doorway, and TP holder dry. tops_rv_wc1.jpg

    We might look into a prefab set up like that later on in the design, but we weren't looking to put a shower or sink in there for now. Just an enclosed head. There will likely be a vent on the door to allow cross venting out the fan and to draft in the cold air conditioning. The port light and LED lighting should supply enough light to finish your, um, business?

    I like the idea of a shower, but that requires a pretty big waste tank too.
