Just the picture, there are 2 more pics, however none with ID plate/number

Hi, Just ran across this boat, I am curious if anyone can help me on the type, builder or designer of this boat. Thank, Marc

Thanks on the rowboat tip, unfortunately not a rower... Funny to see your reactions where I am asking if any of you have any experience in strength calculations building this way. As explained we are looking to do a one off for test purposes. Not looking for the cheapest or lightest way. What...

The hull will be glassed inside and out, no foam exposed anywhere. I know it doesn't make sense, however we want to compare this type of build and explore possibilities. That's why I'm curious if there is any experience with strength calculations using this method.

Indeed, it takes up a lot of space. This is accounted for in the design, I am looking more specifically for major drawbacks construction/strength and durability wise. The bare weight will be around 600kg. However, This will be dependant on the thickness of the glass skin and the density of the...

For test purposes we want to build a 24' open motorboat. We are thinking to have the basic hull shape milled out of XPS (or comparable foam) with high density inserts on sharp edges and for hardware mounting. Finish this shape with glass skin/epoxy resin. Since the foam doesn't serve as sandwich...

Thanks for the useful comments! Will keep you posted on future selections.

My apologies for not being clear enough. The CW Hood example was for clarifying there might be other reasons to go for electric i.s.o. choosing the most efficient drive. By the way, for ultimate efficiency we hoist the sails and get free propulsion. Indeed I don't know much about props, if I...

Thanks for the replies! My prime mover selection is not at discusion, there has to be an electric drive. This is by customer choise, local regulations, space issues and/or ambition. We have a CW Hood 32 daysailer fitted with a 2kw Poddrive and a lithium battery stacked out of our way, this...

Thanks Yobarnacle, For a (potential) customer we are setting up an idea for an electric driven boat, full electric, or hybrid electric. The customer wants to have extra power when needed. Going upriver or running for bad weather. Hybrid electric is our first thought, however it would be a waste...

1 HP will indeed will always be 1 HP, no magic here or any expected magic. However the engine characteristics are way different, Electric motor @ idle: 0 RPM, Diesel @ idle: 600 - 900 RPM. I'm not trying to reengage any HP threads, I'm trying to figure out if there is any significant to achieve...

I have read quite a few posts on power differences on electric driven versus diesel driven. I conclude that you can go for a lower shaft power on electric compared to diesel. Most likely because there are no auxiliary components to drive like pumps and alternators etc. at least, I like to think...
