Yes, we made a hatch
dodger, for our forehatch. The first one, we made it out of a
cheap tarp; the next one was Stamoid, and it has lasted quite a long time. I sewed it on my old Pfaff 130, before I
sold it, so a sturdy home machine is adequate to the job, and no walking foot required.
It is on a dorade principle. The forward baffle comes up from the bottom, and the aft one comes down from the top. Probably the cheapest thing to use for spreaders, is 1/2" dia. pvc pipe. We had a bunch of old flat
mainsail battens that I used. You need spreaders to keep it all taut. On our
boat, we only want the hatch open to about 45 deg., so that was incorporated into the design. If you decide to make it out of Stamoid, for its waterproof qualities even the heavier grade is easy to sew with a #16 needle, or a 14, if you use ptfe thread.
We are house sitting now, and the drawings for the hatch
dodger are all on the
boat. If you send me a PM, I can go out there soonish to get them. But there is no magic involved, and all the numbers are based on the size of your hatch, and also, if you have a baby stay or a staysail stay to hook it up to. Another way to do it is with
fiberglass bows, like a baby buggy
hood, so you have to decide which is easiest for you.
