The A2024 is our go-to triple sheave, low friction, fast rolling, small pulley. It’s lightweight and strong, making it ideal for dinghies, windsurfing, kitesurfing and anything else that runs smaller diameter lines.

Triple blocks are generally used in systems such as cunninghams or vangs, to give a larger purchase system.

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

Ultra-Strap – Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Becket – Our 20 & 30mm blocks offer a large central rivet which not only reduces the overall weight but also offers a rope friendly attachment, perfect as a tie-off point when being used in a cascade system.

Safe, Strong Sun Protection for Little Ones!
Size: 6 Fl Oz (Pack of 2), Style: Lotion Twin Pack
Banana Boat 100% Mineral Kids Sunscreen has become our go-to for sunny days! I love that it’s made with natural, mineral-based ingredients and doesn’t have all the harsh chemicals. It goes on smoothly for a mineral sunscreen—yes, there’s a bit of a white cast at first, but it rubs in nicely and gives me peace of mind knowing my kids are protected with a gentle, effective formula. We’ve used it at the beach, playground, and just running around outside, and it holds up really well. No irritation, no breakouts, and best of all—no sunburns! It’s also water-resistant, which is perfect for active little ones. I’m so glad to have found a sunscreen that checks all the boxes for safety, protection, and reliability.

Great sunblock for the whole family, not just the kids!
Size: 6 Fl Oz (Pack of 2), Style: Lotion Twin Pack
We love this sunblock! It goes on easily, absorbs quickly, lasts as expected (1 hour during water play, 2 hours otherwise), and isn’t sticky or uncomfortable. Blue Lizard sensitive started giving one of my kids a bad rash, so we switched to this and haven’t had a single issue!

Our family's go to sunblock
Size: 6 Fl Oz (Pack of 2), Style: Lotion Twin Pack
This is my go to sunblock for my kids. It's mineral so there's obviously a white cast. I don't mind it for kids because I like seeing where I have applied so I don't miss any spots. I've never had a sunburn while using this and I'm not the best about promptly reapplying. The cream is a good thickness and softness. Not so thick and gooey that you hate the feel of it. It doesn't have a terrible smell but just like a standard mineral sunscreen smell. Does require a decent amount of washing/ gentle scrubbing to get it to come off the skin.

Seems to work well, and less toxic than many sunscreens
Size: 6 Fl Oz (Pack of 2), Style: Lotion Twin Pack
I'm an avid hiker and bought this for me, trying to use less harmful chemicals. Defiantly sticks on thicker and I see residue on the interior of the car, but can clean it up. Seems to stay on well, and work well. And it's not supposed to really disappear into skin. Supposed to sit on surface more. I don't mind having white, obvious, sunscreen. I don't use it in town. Wanted kid ish safe - so it's safer for me.
