Re: [bolger] One-Man Liveaboard Concept

Susanne: I indeed see the similarities between the two designs, and I really like your idea of using the proven #428 Marina Cruiser (aka Merlin) construction details as a base-line for realizing Cartoon #18.  I'd be interested in building the design using laminated plywood frames with lapstrake plywood exterior, as opposed to the traditional carvel planking over bent frames-- more along the likes of the plywood Chebacco boats.  My experience building Cartopper stitch-and-glue helps the cause if this construction technique is possible.

I think getting truer to Phil's drawings may require pulling one of Payson's boat modeling methods I learned, the lift method, out of the proverbial magic hat to generate frame shapes and sizes.  I'll see what I can gather from the cartoon details and see where it takes me.

Thank you for your offer to help realize the Cartoon #18.  I'll forward my thoughts and ideas to you soon by mail.

Barry,
   no she was apparently never taken any further.
However, #428 ‘Marina Cruiser’ a.k.a. “Merlin” on 21’3” x 7’10” x 2’4” with an little diesel-inboard comes closest.
You’d know her from Phil’s “Boats With an Open Mind”.
I recently ran a piece on her in MAIB of May 2015.

Important is the fact that #428 was indeed built and continues to be used.
Curiously, #428 was drawn before the SBJ Cartoon.

Here is one option just using #428:
- Delete that forward inboard-diesel geometry to open up her floor-plan to match the SBJ layout, with instead a 25HP big-prop 4-stroker perhaps
- super-impose as much of the SBJ-profile on #428 as sensible,
- add another 8+ inches of draft to match the SBJ profile,
- and reconfigure her sail-plan from the single Dipping Lug to the Cat-Yawl rig of the SBJ proposal.
On the latter, we might want to consider a MICRO-II type rig for a conventional but tabernacled mast paired with a high-peaked well-battened gaff for maximum sail-area with the shortest main-mast.
This allows both a reasonably conservative main-mast-&-sail geometry along with a main-mast that folds down 85+-degrees to about within her own length, a comforting option when you are facing foul weather on an anchorage, or with a full-length mast-tent facing weeks of sea-gulls in her tie-up spot.
As a liveaboard, just keeping the snow or just frost off deck and hatches might be attractive.
Early in the 5 years aboard RESOLUTION one of the cats raced around on deck one late November and skidded overboard on frost; yes cat will holler when in the water !

Having worked with Phil for 15 years, I’d be happy to take this on.
If you are interested, we should talk offline.
Especially when this would come up.
I am committed for a bit.

Hi Susanne,

 

I believe the Cartoon #18 was published in SBJ #42, April/May 1985.  Thanks for checking on whether this cartoon ever made it to the plans stage, or if any further information/drawings were completed by you and Phil.

Barry,
   which month/year issue of SBJ ?

I'm curious to know Bolger Cartoon #18 "Liveaboard Sailor for one," SBJ #42, V16-N03, ever made it to full-size plans?  I think the idea is brilliant, and the single-berth obstacle others have written about could be overcome by designing a sliding pull-out double-berth, or nearly a double.  I can see myself exploring the San Juan Islands in retirement in a small pocket cruiser like this one, with seasonal trailering possible to other locals.


I'd like to build a 1-1/2":1' model of the cartoon concept if I can gather enough design data together from the cartoon.  If the keel construction were along the lines of long micro, I could use the model to help determine the best position and volume of the lead ballast.  Phil mentions in the Cartoon #18 text that the design displacement of 4750 lbs. would allow up to 1500 lbs. ballast.  However, looking at Long Micro's design ballast of 530 lbs., Phil may have been speaking about maximum ballast here.
