How difficult will this change in width be?

[Pj0915]

My current short board is 5’10 x 19’. I’m looking for a new board for the winter and I found a used one I like but the dimensions aren’t 5’11 x 18 5/8. Would this hoard be noticeably harder to ride?

Well, it depends on the outline of the board. 3/8 inch of itself is very little. But the width is just the widest point of the board. The board might have a very curved outline or a straight outline, or wide point forward or back. Thickness is also relevent

In other words: width is one of about 15 factors to take into account. you cant make any decisions based just on that.

Would this Board be noticeably harder to ride?

1) Same shaper and model ? If not, then YES.
2) Same Tail, Rail, Bottom contours, Rocker ? If not, then YES.
3) Are you looking for a "step up" board for larger winter waves ? If Yes, then this isn't the right board for that.
4) Are you a "good" surfer ? If Yes, then NO problem, because good surfers can ride anything.
