I recently purchased 2 yukon yaks. Love em to death. Been on a couple of 3 day trips so far
(all this weekend warrior can afford right now). My one problem is that one of my rafts has had
a slow leak in it from day one. Before the rafts even hit water I noticed this. At first i dismissed it
as changes in air temperature, or perhaps I didn’t tighten the mouth valve, or main valve quite enough.
But after several days and some light flatwater trials, it was pretty evident I had a leak. Takes a couple
of hours for the boat to get noticeably ‘squishy’.
This is not a complaint, or by any means nocking the quality of alpacka rafts. I would imagine that
most or all boats are pressure tested for some length of time before leaving factory ? At any rate,
it could have easily been a result of shipping, as when my package arrived it came in such a battered
state, that one might think the box had been kicked and dragged all the way from Alaska to Ontario,
through all imaginable weather. I have a chronic E-bay problem, so i’ve seen many a bruised and battered
packages come out of the far east, but the wreckage of box my rafts arrived in, takes the cake.
Gotta love the canadian postal system.
At any rate, I figured this was a good learning experience and first hands practice for patching my boat
myself. Figure this is a skill I am bound to need at some point, so not really put out by the whole issue.
My problem is, finding the leak has proven way harder than first imagined. It is obviously a very small
and difficult to find leak. I tried slightly diluted soap and water over all the seams of the boat. Then I
tried to force-submerge the raft in fairly calm flatwater in hopes of displaying the tell-tale bubbles. Then
I went out and bought some ‘leak-detect’ soap with brush in bottle and started meticulously going over
all the seams again, making sure to check valve seals. I just can’t seem to find this pesky leak. If I had
a bigger bathtub I would try submerging the raft in that.
All I can think of now is making up more soap test and painstakingly going over every inch of every
individual panel of the boat until i find the pinhole leak.
Anyone have any insights or tips to make this process easier? There has to be a better way, no?
Also my floor on both boats is delaminating from the tubes in several places. I don’t think this
is any defect in the adhesive product used to mate the flooring material to the tubes. Rather
I don’t think any was applied near the edges of the seams as I can easily peel the seams back
and reveal a line drawn in permanent black marker, obviously used as a guide to align the
floor to the tubes during manufacturing. I am sure this does not affect the integrity of the
floor bond to the tubes, but the open gaps in the overlapping fabric catches debris quite easily.
Will a little aqua seal fix this right up, and close the overlap seam back up?
Overall I am EXTREMELY happy with my purchase, and have fallen in love with packrafting.
While still way more at home in a WW creek boat, i am just getting a cautious feel for packrafting
in bigger water. I can see that maintaining these little boats is going to take a fair bit of TLC.
