I don’t know what you’ve done to the logo but it’s blurry.
The “Riversails” text needs to be completely redone, looks cheap.
The logo imho is on the right track but needs a little tweaking to really capture the feeling of a sail or sailboat in particular. I like how simplistic it already is though.
The harsh glow outside your canvas.wrapper needs to be toned down. Alot.
hide your tags at the end of the <body>
I love the images you have in the slider, very well done but please take off the effects or atleast tone them down.
If I were you I would find something to box in the main content below the images, I find it very hard and boring to read. I tried forcing myself to read it and I got to about line 2.
I mean there’s a lot more but honestly I do like where your website is heading.
