Please Help - Boat Unknown ! (Photos)

[Algarve]

Dear friends,
I need your assistance, a friend of mine is renovating a sailboat purchased already used with many nautical miles.
The help I need;
What is the name of the hull?
What brand?
Is there any chance of someone having an equal?
No chance of getting the manual?
Does anyone have the project of this boat or it may indicate how I can get?
Thank in advance,
Algarve

Interesting hull shape. The draft should be calculatable by dropping a plumb from the points where the waterline touches the port(h1) and starboard(h2) sides of the transom and the bow(h3), measuring the plumb line at each spot, add and divide by 3. If the keel isn't quite touching the ground measure the centre points height(h4) above ground and subtract it from the result. ((h1 + h2 + h3)/3) - h4 = draft

Sorry, did not mean draft, but project.

What is the name of the hull?
I think it is a 29ft Seamaster Sunspeed 1978!
Can someone confirm this.
