Additional floatation question

[jpollman]

Hi all.

I've been thinking about getting the boat ready for the spring season. I have a 16' Rich-Line with a 40 Evinrude on it. I bought the boat early last summer and did some re-working of it.
I removed the old seats and installed some new ones. I also added a forward "casting platform" or deck between the front bench seat and bow. I do have some rigid foam floatation inside the bench seats but I was thinking about adding some additional floatation "just in case" . I've got quite a bit of unused space up under the casting platform. I talked to Esox about it. He suggested spraying in some foam. Sounds like a quick easy way to go about it. Have any of you tried this ? If so, how did it work ? And also, where did you buy the material from ? I have some places I'm going to call on Monday but just thought I'd throw it out here for a little discussion.

I may be a little paranoid but the way I feel "you can never have TOO MUCH floatation" !
