For those looking for a little extra storage on the M170. I recently added a storage compartment beneath the RPS cushion on my M170. The compartment is only large enough to hold two tackle trays and a few odds and ends, but it more than doubles the fishing package tackle drawers. The compartment is made of 1/2" starboard and has interior measurements of 29" x 9.5" x 2.25" and clears my Pate 27 by more than 1/2". Total cost less than $75 (not including tackle). I've a couple of pictures of the finished project at:

That is a great idea and it looks like you did a quality job. Thank you for sharing.

Awesome job, George! The factory could take a lesson from that!

Great job! I always like looking at people's Montauk 170s and getting ideas. Now you have me wondering - if I had used your idea I could have put the fuel fill for my aluminum tank under the seat and still had room for storage.

Please forward photos and your idea directly to Whaler. They might include it in their 2004 models.

Thanks for the all of the positive feedback.

Tabasco, I sent the idea to BW, let's see what happens.

Any response from whaler on you idea and photos? If not they are sleeping on the job.

Once again a great idea for additional storage space.

I haven't heard anything from whaler. Not even if they received the e-mail. So I sent it to another address I have for them.

Thanks again for all of the positive feedback. I think this board is fantastic and am grateful to Jim for giving us a forum where we can share our ideas. I can't wait to put Barney's rod holder cushion solution in my boat.

Any word from BW on your rps upgrade? I think this should be standard or at least an option on every new Montauk.
I also wanted to bring this back into the last 10 day post period so I can admire the photos your boat easier. Thank you again for the great idea.

Don't be so bashful with all those nice pictures of your 170 MONTAUK.

Show them this link:

and let everyone see all the pictures!

Have you considered starting a little side business? I would be the first to order the seat insert. Let me know if you are interested and what the cost would be.

I am serious.......really love your idea and the quality of your execution. Just e-mail me as to the cost.

Thanks for all the complements.

I did receive confirmation that BW received my suggestion, If I were at BW, I would complete the RPS mold and have a fiberglas pan beneath the seat cushion support panel, then put a finger hole in the starboard insert. I gotta believe that a quart of resin and some mat would be less expensive than 640 square inches of starboard.

Tabasco, I'd love to have the time for a side business, especially doing things that I love, but other commitments won't allow. This project was fairly simple, so I put together a step by step to on how I did the job.

You may be able to find starboard at a local supplier. If not, I bought the Starboard from Prospect Plastics in Ft. Lauderdale, their phone number is 954-564-7282 and e-mail address is or check their website:

The parts list consists of the following:
Label Quantity - length x width x thickness, description
A 1 - 30" x 10" x 1/2" floor of the compartment
B 2 - 30" x 2.75" x 1/2" forward and aft walls of the compartment
C 2 - 10" x 2.25" x 1/2" side walls of the compartment
D 3 - 9.5" x 2.25" x 1/2" inside rails that support the lid (seat)
E 1 - 29" x 2.25" x 1/2" aft inside rail for support of the lid (seat)
F 60 - 1" #8 oval head SS screws (Phillips)
G 10 - 0.75" #8 oval head SS screws (Phillips) used to attach the lid support rails

Note: The size of my storage compartment was determined by the available space between the bottom of the cushion support panel and the top of my fuel tank with a minimum clearance of 1/2". I have a Pate 27 installed, if you have a different tank(s) your available space may be larger. If this is the case you can add to the width of Parts "B", "C", "D", and "E" and make the box deeper.

1) I pre-drilled (and countersunk) the following holes:
Part "A" - drill 4 holes evenly spaced along the 10" side, set 1/4" in from the edge, no closer than 1" to the corners (for attaching to Part "C")
Part "B" - drill 10 holes evenly spaced along the 30" side, set 1/4" in from the edge, no closer than 1" to the corners (for attaching to Part "A")
Part "B" - drill 1 hole centered along the 2.75" side, set 1/4" in from the edge, (for attaching Part "C")

Note: Using the pre-drilled holes as a template, I drilled pilot holes in the pieces being attached, this will prevent the material from swelling once the screws are in.

2) Attach the forward and aft walls (Part "B") to the outside of the compartment floor (Part "A") using 10 screws per side, this will make the outside dimensions of the base 30" x 11",

3) Attach the side walls between the legs formed by the forward and aft walls using 4 screws up through the bottom of Part "A", and 1 screw (each side) in from Part "B"
At this point you have a shallow box with outside dimensions 30" x 11" x 2.75", and inside dimensions, 29" x 10" x 2.25"

4) The next step is to pre-fit the box to the cushion support panel (the starboard seat base insert). I centered and marked the position of the box on the underside of the panel. Then I marked the location of the screw holes that will attach the box to the panel. I drilled 4 pilot holes and temporarily attached the box so I could set the panel (with the box attached underneath) in place to confirm the fit. I also confirmed that the box would not interfere with the fuel hoses.

5) Once happy that the box will fit in place, drill (and countersink) the remaining mounting holes through the cushion support panel ( 10 + 10 + 4 + 4 = 28 holes total) and mark the location for cutting the 29" x 10" lid. Once marked, remove the box before cutting the panel. Mark the box and panel so you can re-attach it later. I used a circular saw to start the cut and to cut the straight portions of the lid, then I finished the cutout using a sabre saw. The sabre saw allowed me to radius the corners of the lid.

6) Next install the lid support rails using the 3/4" screws, place Part "E" along the aft wall of the box and attach by drilling a pilot hole from the outside of the box (mark the drill bit so you don't drill completely through the material. Repeat the process on each of the short sides using 2 Part "D". Lastly install the center rail, I set my center rail such that one side would accommodate a series 3700 tackle drawer and the other side would accommodate a series 3600 drawer.

7) Cut the finger hole, taking care to place it where it will not interfere with the placement of the center lid support.

8) Next drill a small drain hole in each of the aft corners so the box will not hold water.

9) Lastly, mount the box to the underside of panel and re-install the panel in the RPS.

I was going to begin my process of installing the underseat tray on my Montauk as described in this thread. I can still do it but the photos that were on the site are now gone. Can ghefty or anyone else who might know where those photos now reside point me to a new page with them? Thanks!

ASIDE: Unfortunately a five year lifespan can be an eternity on the internet. Dead links are a problem. One of the fundamental reason why CONTINUOUSWAVE has not changed its format substantially is to preserve over 100,000 links to older articles which remain available, some going back over 14 years.
