Re: 2x newbies fancy scuba diving off Kayaks

I have used a SOT for snorkelling. Many of the larger models have ample storage for tanks etc. Have a look at the kayak fishing sites for anchor fitting instructions, or buy a fishing spec kayak with the anchor gear already fitted. I think you would be better buying two kayaks rather than a tandem. ...

Re: Pumps. What's the best option?

Ian, I'm afraid that there really isn't any way to make a useful estimate of the quiescent consumption of the DC-DC converter. It depends very much on the components used. Using the best options it could probably be made to run for months, but there is no reason to suppose that was part of their des...

Re: Pumps. What's the best option?

Ian, the all in one Li-ion looks really good value for money, especially when you consider that the charger is included. You would struggle to get a SLA and charger for the same. Unfortunately, there may be a snag. The unit has a on-off switch on it, probably because it uses a DC-DC converter to mak...

Re: Foam in the cockpit and osmosis

I think the verdict is that putting foam in isn't really going to cause a problem fast enough to be an issue. Thanks for the links for buying foam, I'll work through them all when I know what size and shape I need. Another option has occurred to me. How about installing a second bulkhead and then pu...

Foam in the cockpit and osmosis

I am just starting to think about customising the cockpit of my NDK explorer HV. The aim is to make use of the excess space, or failing that fill up the unnecessary volume. For instance one mod I am considering is fitting a 5l water contain in the space beyond my feet surrounded by foam, as I have s...

Re: Solar Chargers ... anyone?

I think you need to be realistic about your expectations from solar. Even the super powertraveller only has a 3W solar cell. That is 3W in ideal conditions, or probably about 1W in the real world at the kid of latitude we kayakers seem to prefer. This means that the maximum you are really going to g...

Re: How do you self rescue from mud?

The density of mud is about 1700kg/m^3, or heading for twice that of water. I can see no mechanism from simple physics that would explain how a boat could sink into mud, in fact it should ride higher than when in the water. This suggests that staying with the boat is the best course of action.

Re: Standard Horizon HX851E

I think the argument against DSC goes like this. Having some flares is a smart idea. Having more flares is better, certainly, but investing the same money in a VHF would be better. The thing is that it is a different vector to help. Flares may not work simply because there is nobody there to see the...

Re: Kayak colours

The kayak already has a fair few scratches, so there is no risk of me getting overly precious about it. That is one of the reasons that I chose a used boat; that and not having enough money to buy a new one! Removing the hatches on a hot day seems a pretty good idea anyway as it will allow the sun t...

Re: Kayak colours

The explorer I tried first had an orange deck and white hull. Unfortunately, I didn't fit too well, though I think I could have lived with it. The HV version is pretty much identical to the standard version except for the knee bumps. (Other manufacturers HV boats can be very different from the stand...

Kayak colours

I have pretty much decided to buy a kayak. A SKUK explorer HV. The boat fits me well and it seems to be in good shape. The only fly in the oitment is the colour - it has a light blue deck and a black hull. Not a great combinantion aesthetically IMHO, but I am an enginner so what would I know about a...

Wanted sea kayak - Bangor, North Wales

I'm looking for a cheapish sea kayak. It doesn't have to be pretty, but it would be handy if it was at least nearly sound.

Many thanks

Re: Valley Nordkapp RM or SKUK (NDK) explorer?

Thanks for the responses. I know in an ideal world I should try both, but the Nordkapp is 150 miles away and there is only flat water there to try it on so I doubt that I will be able to get much beyond how well I fit in the boat. I can get that from just going to a local kayak shop and being cheeky...

Valley Nordkapp RM or SKUK (NDK) explorer?

I am looking for a sea kayak. Initially I will only be using it in relatively large groups for day trips. I would like to think that eventually I will use it for overnight stops and weekends away. I am 5'8 and weigh 14 stone, quite a lot of it lard. I have done most of my sea time on an OK Prowler E...

Edging - how does it work etc^

The discussion of stability i the Tiderace thread was fascinating. I wonder is someone wouldn't mind expanding this into how edging works. In a sailing boat you tip the boat *away* from the direction you want to turn in order to use the shape of the hull to turn with maximum efficiency instead of ra...

Re: New Tideraces

The stability curves are fascinating! I have never seen real data for a kayak before. Looking at the stability graphs, I think that the feeling of stability "stiffness" is going to be the gradient. This means that these kayaks are never more stable than when upright and between 25-30 degrees the gra...
