Best way to attach a Forerunner 305 GPS to my boat

Just wonder if any of you could share methods you've used to mount a Forerunner GPS watch to your boat. It needs to be mounted on an angle so I can read it. I'd still like to use it as a watch for other sports (meaning I don't necessarily want to remove the straps every time). It's being attached to a Fusion. I was thinking of attaching it to the ridge between the footwells.

My next question is going to be how would you recommend I have the chines removed from my boat. After the latest discussion, I've just been blaming them for me being slow.... Just Kidding! I love my boat. Solidly built. Beautiful. And I know that at least the boat is competent in big waves - even if I'm not.

The simplest and most effective way is with velcro. Just mount the hook side on your center between the footwells and then use strips cut from the other side to secure your GPS. You can buy all of th parts from Home Depot.

my clever buddy showed me a good way to do it. but it's too hard to explain. it uses scrap aluminum from an old road sign and double sided tape. you never even have to change out the wrist strap from the 305. just loop it through once you have the metal mounted and it sits facing you perfectly.

thanks Poops!

I'll try to post a picture later on.

Cheap way to do it with easily procured items:

Secure the 305 to front iaku using wrist-straps.

Equipment required (found at Hardware stores/HomeDepot):

  1. Polyethylene pipe insulation, 1"x6' $4.00
  2. PVC pipe wrapping tape (10 or 20mm) $6.00

Cut a 3" piece of foam and wrap around front iaku. Wind a few wraps of PVC tape to secure firmly enough so 305 won't spin. Attach 305 with wrist strap.

The PVC pipe tape has many other uses; lots of surfski/OC paddlers apply to areas of boats that get dinged around cockpit for added protection.

On the 305, I use the 3-panel view and can see it fine but mess around with what you want so you can see it too. Works great IMO.

Where'd you get the suction cup and how did you attach it to the garmin mount?

I just wrap a tire rubber around the front iako until it's thick enough to strap on the GPS.

Yeah jc9 is right, we have a super good SUPER cheap way of attaching forerunner 305. Its too hard to describe. Hopefully he'll post a picture of it and I will try too but probably not.

through my calculations it costs about $0.12. The aluminum sign was free and the double stick tape (prorated) costs about $0.12. Just be sure to rub the areas that the double sided tape sticks to with rubbing alcohol. Then you get a super duper bond.

Damn, $0.12 sure beats my $10.00!

This is the type of thing that a photo's worth a million posts...

I attach mine to the front iako. Using one of my kids pool toys. Its a long piece of foam called a noodle used for floating around. Cut a section off the end and shoved it around the iako. To add security when its rough I stick a ziptie thru gps and the foam. Noodles cost about a $1.50 at the toy stores.

I do the same thing as poopoo and jc9, except I use a smaller piece of tape... mine only costs 8 cents.

I got the suction cup from a portable Kayak light. It has a screw buried in it, all you have to do is drill a small hole at the bike mount receiver and screw it in. I suggest you attach a small floaty, i have to dive on it once. get a bike mount for your 205 or whatever garmin you have.

Yup, did something very similar with mine. Same bike mount available from Garmin and a conduit elbow inserted into a suction cup with a hole in it.
