Re: Sevylor or Intex?
I took my new Mariner 4 out for it's 2nd trial yesterday, opening weekend for many lakes in Washington State. I continue to think: What a champ that boat is!
I was planning to work on my solid floor this weekend, but one friend coaxed me to brew beer on Saturday and my son-in-law, who just got his fishing license for the new year fishing that started April 1, talked me into fishing on Sunday! Given my sitting discomfort on my last trip, I thought I would experiment with my old seat. As described elsewhere on this site (including photos), I had a boat seat on a swivel on a board, cinched to a milk crate and a plywood floor board in my HF-360. Not attaching this seat to the floor caused me to go in the water, and not willing to risk it here, I tried putting the whole thing, including the much smaller floor board, on top of the slatted floor in the Mariner 4. It worked like a charm! I was raised off the floor, had a seat back and could swivel!
I'm happy to provide info on how I plan to modify this boat, based on what I now know of it and past experience with a Sevylor HF-360, but for others here, Loop_Dad had done some great things with his Mariner 4 that he has had since at least last year, so don't overlook him as a very good resource! I know I rely on his experience.
There was a request for rough dimensions for the Mariner 4. This may be too rough, but I get about 9' by 3' for the floor. I'll be able to provide more exact numbers as I shape the wood.
At this point I am looking at using 1 sheet of plywood (4' x 8'), 1/2" thick, or the next size thicker, if I have to. I will cut the sheet to make it a 3' by 8' board, and then cut that in half to make two, 4' x 3' pieces. One will be for the back, one for the middle, and I will use the 1' x 8' piece to make a 1' 'nose cap'.
As BeachBlue suggests, I did make such an 'H-Beam' to join the 2 floor boards I had for my HF-360 but found it to be unnecessary. The rigidity of the floor and side tubes held everything in place nicely, though stepping on only one board near the joint did cause a step-up of 2-3 inches. My impression at this point is that such a joint might not be necessary for this boat either, but that is simply an educated guess.
Forgive me if something's been asked that I have not responded to. My intent was to 'get' everything.
