Best padding I've found for my ancient rear end!
Ropes are great quality and do the job they say they do! Would highly recommend - price is also a lot more reasonable than equivalents from other companies
Much better than those we previously got from a large DIY super store. Stronger and easier to fit.
Just used my new launching trolley for the first time.
Super easy to assemble (about 3 minutes). Fits my laser perfectly and very easy launch and recovery.
What more can I say....other than I would happily recommend.
My local chandlery were unable to supply a white inspection hatch and so it was amatter of looking online. Sailing Chandlery had the cover I needed in stock at a good price and delivery. I had never used them before but the service I received was excellent with the delivery on time and the hatch is now fitted.
I will definitely return, especially with the discounts on offer. Thank you Sailing Chandlery!
I have a old but still fast Laser from the 70s that I have been gifted, I am doing some tidying up, and have noticed that the toe strap elastic was tied to the traveler. So I have changed it to the Laser Anodised Traveller Cleat, this great idea secures the elastic and stops interference to the traveler by keeping each part separate.
Perfect size, shape and works well
Needed 5m of a low stretch rope to act as a mast raising / lowering tail on my Wayfarer forestay as the existing 5mm rope was a bit thick to pass under my reefing spar attachment. Now it fits snugly and the mast raises and lowers better than it did before because of less friction and "bounce".
The top cover was delivered on time as expected. The cover fits perfectly and hopefully it will last forever … Thank you
Bought this for my son so can’t personally comment as I’ve not used it. However he was very pleased with the purchase and said it’s great quality.
Always happy with my orders from Sailing Chandlery. They are quick to post and very helpful when I have had a question.
Jason delivered the boat on time at Hayling Island Sailing Club. The boat was new and all the spars were in perfect condition. Jason came to pick up the boat and return the deposit which I gave at the time of the delivery. Every interaction with Andrew and Jason were handled very professionally. I will recommend to any sailor Sailing Chandlery in the future. I really appreciated how easy it was to charter this boat. Thank you very much. Jacques Kerrest
This was a birthday present for a sailing daughter (i don't sail!) She was delighted, it hasn't been out on the water yet but she's looking forward to trying it out and says it's just what she wanted... so looks like a good choice by me after helpful advice from Sailing Chandlery staff!
