Surely OP you're able to give a little meat on the bone:
location,
length
photos from different angles (especially stern and bow)
close up of what looks like a logo
name of vessel,
your own thinking.
Just guessing
designer names by recognising what appears to be stylised W that may or may not reflect the designer's (or builder's, or owner's name). Maybe the
boat is just called W or owned/once owned by a
charter firm and it's their logo.
