Steve13,
I happened across the Seadog website last year and became inspired. I tried contacting them, but it appears they were in business only from about 2002 to 2008. This led me to try to duplicate what I like about the Seadog as a DIY project this March and April. Locate the "Pram build" thread in this sub-forum and you will see photos of the pram being constructed over about 6 weeks. (It doesn't take that long to make it, but there are a lot of days spent letting epoxy cure, primer cure and dry, and paint and varnish dry and cure.
My pram is not identical to the Seadog. I made a flat bottom, rather than curved side to side, and I built mine a few inches wider, wanting the room and stability to take grandsons fishing in the not-too-distant future.
Fred posted in that thread, and he now owns the Seadog pram Dick refers to above in this 4 1/2 year-old thread.
