Re: Hull layups "core" technology vs single skin

so, cork is not used in large scale production since it's hard to source it in a consistent quality/density? I guess the balance for cost vs benefit is not that favorable and there are other materials more widely accepted, to make cork a niche market material. I just like the idea to have a core ma...

Re: Hull layups "core" technology vs single skin

I find my lo tech core material works very well. Western red cedar. Natures best. Have you considered the ultra high tech (but rarely used, because expensive), natural material, cork? Yep, good old cork that resists compression and springs back if compressed, without leaving a big dimple? No Asian ...

Re: Broken coaming

it is not totally unusual to see such damage on a sea kayak that (from the images) seems to be made of CSM While CSM is great for thick laminates is seems to be a weak choice when laminated thin. SKUK uses CSM but unapologetically say it's easier to repair when holed. Their kayaks are not light, th...

Re: A "good paddler"?

I am not sure if there is a standardized way of "measuring" the traits of a good paddler so I believe the answer could be subjective. While one could mainly focus on a paddler's speed that does not constitute necessarily a good paddler in my book. What I value however is skills that are applicable ...

Re: How difficult is kayaking with a sail?

Two wee holes for a mast foot are not much bother once you have fitted a pump! do you have a pump fitted in your front hatch too? or is there no bulkhead? :-) Now seriously: two little holes make no difference especially if the holes are drilled a bit undersized and the bolts have to expand the pla...

Re: How difficult is kayaking with a sail?

Douglas, what I was thinking of instead is the epoxy putty to be used simply to fill the area around the RDF and not really sticking to it necessarily. I think the RDF is slightly lower than the deck surface and the epoxy putty would fully cover the whole area with RDF enclosed. A hole would be the...

Re: The mechanics of a good "float".

You mention seats, what about a block of foam shaped to preference? They will load spread over the bottom of the kayak and not stress the deck if the usual type is suspended from the deck. I love foam seats: very comfy and easy to construct. But they did not work for me with the electric bilge pump...

Re: How difficult is kayaking with a sail?

the chopping board is indeed a simple solution
the screws I see in the image, are they piercing the deck?
Like e-wan suggest, if epoxy putty is used in the recess dimple of the fitting then screws could go into that and eliminate some holes?

Re: How difficult is kayaking with a sail?

not sure how strong (stiff) is the deck on the RM kayak but you could simply try to push down hard and see how much it flexes in the different locations that you mention. If the flex seems about the same then I think you have the perfect deck layout for a mount without having to drill holes for the...

Unless the evidence of prior samples is really compelling (in this case, yes) the patent is not valid.

What you are saying, or so it sounds, is they can design the lines of a kayak but can't design a package which includes hatches, skeg, rudder, cockpit etc. etc. If they are forced to buy off the shelf items it means there aren't any designers in the Northern hemisphere who can do a good job?

I have a couple of PT65N kayaks. Admittedly I like tinkering but not replacing broken parts. Skegs on PT65N are rubbish and need work, a lot. Best if replaced with a decent one right before it leaves the shop. It seems that PT65N kayaks have been getting worse throughout the years. The reason I kee...

Re: Foot Pumps

I agree with Mick: hand pumps and foot pumps are rather slow. Electric bilge pumps are VERY reliable if installed with care; what gives them a bad rep is cobbled up jobs that don't pass the handyman test. So far I have installed 15 electric bilge pumps and only one failed when the user (not me) rip...
