There ya go. Were they multilayered and "cold molded" in real life ( poor choice of terms I suppose) ? or is that just a modern construction bent?
I assume you have it strip planked and then cold molded.... Nice shape! It looks very fair! :ThumbsUp: :cheers:

and the reason why I ask, is I know where some of the smaller more enigmatic engines might be.... If you're interested in specific detail.... I know where a K is...and I've only seen 2 ever.
tghs:
the pictured hull is a 1/16th scale (4ft) RAF whaleback double diagonal planked (the same method was later used on US PT boats) I've have detail photo's of the engines and many discussions with their owner on what changes will be required in the scaling down process.. the foot print will be close,, the frames will be a bit more robust,, the entire block/valves unit will be a little longer,, just a tad taller.. all in all it should be good scale live steam model.. planning on building the hull very close to the prototype in regards to methods and materials.. have 3 select eastern white cedar boards that will provide the planks, white oak for the frames and keel,, I may replace the ash with another pale wood as finding ash with a finer (scale) grain pattern has been tough..

That's great! I really look forward to hearing and seeing more!.

I'm No boat builder so I may have this totally wrong. I am surprised at the use of ash wood on a boat, I have only used ash wood to build the frames for vintage car bodies, the wood frames were covered with either metal sheet skins or fabric. The ash frames were used because ash was a light flexible wood, but it tended to wet rot after a few years due to the effect of rain water etc. So you can see my surprise at it being used in a marine environment. Hope you find a suitable replacement.

the ash was used as trim alternating with cherry,, it more importantly was used in the seating slats that were bent to follow the curve of the stern.. most of my 30ftr files are to large to post but some 40ftr info give you the idea,, all of the "trim" wood would have been kept in a good coat of waxed varnish..
