JEM Watercraft

Hello Builders,

got a new day camper on the drawing board. For some reason I keep getting back to these Dutch lines









The boat has a length of 4.520 m [14' 10"], beam is 1.610 m [5' 3"] and the draught is 0.248 m [10"].

At the time I made the preliminary design the idea with the boat was to take my daughter (she is just as crazy with sailing as I am) and me on daytrips to some small islands not far from here or along the cost. It was also essential that the boat had a cabin for two to sleep if needed. Another nice feature that came during the design process is the self-draining cockpit. The boat is at this stage designed with a junk rig. I am not sure it will stay that way but it was more like an experiment and because I have been studying this rig type for a while and it fascinates me. Hopefully it will not be necessary with leeboards or centreboard, but calculations will show later on.

So any suggestions or comments about the design would be appreciated, it is still preliminary.

That's pretty sharp Morten, and IMHO it would be a mistake to NOTuse the junk rig. You I'm sure know more about them than I, but I've never read anything bad concerning a rig of that sort. And they look cool as hell also!

Good job.

Nifty looking boat. I think a dutch pram along these line in a bright finish would turn many heads!

I sent you a couple e-mails about a design similar to this.

I've never made a sail or sail boat. Can the sail be made or do you need a sailmaker?

You could make everything yourself. The rigging, sail and of course the hull

One possibility is to use the polytarp. I have never tried it but as far as I understand, it is some kind of tarpaulin that you clue together.

Then of course you can buy some sailcloth and sew the sails, but that will require a good sewing machine, I have ruined several when making my own sails but I have succeeded to get the job done every time until now.

If strong enough, I'd probably try something like this:
