Thames Barge race possibly Brightlingsea Regatta ?
It's my best guess, and while the painting is not free,
Speculation regarding the probable event depicted is gratis and to be done at your leisure.
Beautiful windy day for the race.

Let me absolutely assure you that it takes really pleasing, heart warming skill to say so very much using so very few brushtrokes
Should the artist, if he remains alive, see this compliment I should be most happy.

Frame outer size 4
18.5" x 15.5"
Actual picture size ie inside mount size 10" x 6.5"

The artist has gifted us a truly 'rock n roll' event in that he really has vividly captured the turbulence of both of the boats tacking and gybing, as they race. They then tumble in with an eloquent hand, this stunning Turner-esque billowing sky with erupting cumulonimbus.
I loved it (i often attend the regatta time permitting, though often only, only if it is a reasonable wind like that depicted in this item) I bought this truly inspired capture of just such a race, to live with until such time as somebody likes it as much as I did.
It is well painted.... in my opinion .....and beautifully framed and mounted
If you love it, nothing will deter you, since there are no negative issues requiring highlighting.
