Obviously it is in the remit of the builder/owner to name their boat, but may I make a couple of suggestions which both nod to the project name and also plays on the word "sublime".
How about "Siblime" or "Simply Siblime"?
The first study of the value of the sublime is the treatise ascribed to Longinus: On the Sublime. For Longinus, the sublime is an adjective that describes great, elevated, or lofty thought or language. As such, the sublime inspires awe and veneration.
Taking on your project in the first place has inspired awe and veneration in a lot of us mere bystanders.
Yours, etc, Dave D.
