This is one that i,ve yearned after for some considerable years. Had the plans in the 1960's, I think, but it was always put on the back burner. But needs must, we have a big sailing lake now and a Sea Queen looks ideal on this water.
Speranza, built from Plans, first thing source the timber, 5mm ply for keel and bulkheads,and Obechie 6mm X 3mm laminated for stringers and chine lines. Transferring bulkheads/frames to the timber can be daunting, but several methods can be applied. Personally i prefer to Trace the outline and detail then pin prick the outlines onto the timber, you can do this direct from the plan, but using tracing paper or drafting film saves the drawing from disintegrating. Have used carbon paper in the past, but I did find this a bit messy, a personal choice.

After the marking out, start on the cutting out external lines, then remove the unwanted internal ply, a dry fit or several as progress develops. Regards Muddy....

Started on the Stringers and Chines, some of the stringers are Spruce, 1/4" x 1/4" , one cracked on the bow curvature, not immediately it was glued and pinned, but about an hour after, should have laminated these spruce stringers as in 1/8" x 1/4" times 2. Another one has cracked since but they are repairable..
Mixed up a weak solution of PVA and water and painted the rest, hoping this will soften them up and be more pliable. Started on the transom, this is angled with a sharp centre line, but there was a lot of off cuts of Obechie lying around, so it was planked with a curve, first Modelers License applied. A few more dry fits and the bow and transom were assembled up, using stringers as alignment tools, anything will do in these instances even strips of ply. Some of the upper-works combing has been fitted around the transom area. Muddy....

Only three years ago, i shelved this one, and what with the other's receiving paint i was stuck with nothing to do, a quick look into the started cupboard and there she was, Speranza, first purchased the plans in about 1966-ishhh, and in those days a 40 " boat was big compared to the Aerokits and Veron's, Down to the repair to the spruce stringer which cracked because i did not laminate it, as usual practice, applied a splint trying to close up the gap created by the split and added a strip of Obechi to the outer inbetween the first two formers as this had pulled square instead of being slightly curved, Here's hoping tomorrow i can attack it with a sander.

Sanded down the hull, stringers and Transom ready to accept the hull skins, but when opened the wood store the cupboard was near bare, the allocation of ply had been used up, dont ask where, the memory cells are on strike. The combing was added and the propshaft supports, as there are going to be two shafts or twin screw. After these jobs were done i was in limbo and as the frame is rather flexible if not on the point of being flimsey because of the lightness of construction, not my idea. Made a start on the foredeck, with Mahogany planks and a caulking strip, this again was a bit hairaising because of the light framework, but the main hull structure started to be more rigid, here's hoping. There's not a lot more to do because of the materials shortage. More to follow, but not in the near future, not my fault !
Keep smiling and safe..
