I've seen the Splash on the water (and lifted it). It is amazingly light. 18 kg.
To save weight, many of the "std " features like hatches, etc. had to be left out and I agree it is not an ideal fishing kayak for hard-core kayak fishermen like yourself.
If I had the money, I would certainly buy it. I don't really fish all that much from my kayak due to age (60) and cannot launch from the the beach like the strong young guys do. I cannot help but envy them, but I love kayaking and the Splash would suit my needs perfectly, general "touring", and fishing at vetchies, estuaries, dams, etc.
At my age I need the kayak as light as possible.
I am also building 2 Cedar strip kayaks (plans courtesy Stealth) which def. cannot be used in the surf and are intended for touring and general "messing about" on the water.
To each his own, I guess but as has been said many times, different kayaks for different applications.
I'm enjoying your updates on the Bamba and look forward to see your catches.
