    Product Information

    Two-speed mainsheet systems allow both coarse and fine tuning in a single purchase system. The system allows fine tuning of the mainsheet when sailing upwind by using one of the sheet tails and keeping the other cleated. Using both the sheets at once allows the trimmer to blow off the main quickly when rounding the top mark and trim on quickly when hardening up after rounding the bottom mark. When fitting to traveler cars, ensure adequate support for the bottom block and use stand-up spring kit RF324-1 or RF324-2.

    Dove never fails us, ladies! Solid lotion for all over.
    Size: 8 Ounce (Pack of 1)
    They can pump out all the fancy moisturizers and lotions they want - I always come back to the originals. Dove has a brand reputation which never fails. This cream serum is awesome for all over my body after a hot shower (bc it kinda dries out my skin). Face and body, it works. Apply after shower before bed and you have a whole skincare routine. Cannot beat the price for less than $10!

    It's a great deep conditioning lotion
    Size: 8 Ounce (Pack of 1)
    This is above and beyond your usual body Moisturizer! Very hydrating, I haven't experienced any sticky residue. It absorbs quickly, I put it on just after a shower to hold in moisture. Accidentally discovered while using a lotion applicator for my back that it also gives your hair a great deep conditioning! I didn't have any residue in my hair either.

    Honestly the best
    Size: 8 Ounce (Pack of 1)
    I have pretty sensitive skin and have keratosis pilaris on my arms. This is honestly the best lotion I’ve ever used and I’ve tried many many lotions. My skin is soft but not greasy. My arms feel soft which is a huge deal. I’ve been using it for months now and I don’t think I’ll ever use anything else.

    Absolutely Love It – Deep Hydration That Lasts!
    Size: 8 Ounce (Pack of 1)
    The Dove Body Cream Serum with Hyaluronic + Hydration has quickly become my go-to for tackling extra dry, flaky skin — and I absolutely love it! 💧 Deep, Lasting Hydration: From the first use, my skin felt instantly hydrated — and what’s even better? That hydration actually lasts throughout the day. No more reapplying! 🧴 Lightweight & Non-Sticky: It goes on smoothly, absorbs quickly, and doesn’t leave that greasy or sticky feeling — just soft, nourished skin. 🌿 Skin-Loving Ingredients: With pro-ceramides, niacinamide, and collagen peptides, it feels more like a high-end skincare product than a typical lotion. My skin looks visibly healthier, more even-toned, and has a soft glow. ✨ Bonus: It’s gentle enough for daily use and has a clean, fresh scent that’s not overpowering. If you’re dealing with extra dry or flaky skin and want something that works and feels luxurious, this is it. Dove nailed it with this one — hydration, comfort, and glow in one bottle. #DoveBodyCare #HydrationThatLasts #SoftHealthySkin #DrySkinSolution #SkincareMustHave #GlowUpWithDove

    Soft Skin All Day Without That Greasy Feel
    Size: 8 Ounce (Pack of 1), Size: 8 Ounce (Pack of 1)
    My skin is dry and tends to get ashy, and after showering it can look worse, especially on my hands, elbows, knees, and heels. I apply this while my skin is still slightly damp. It goes on creamy but absorbs quickly, so I don’t get that greasy or sticky feeling some lotions or body creams leave behind. I can get dressed right away without waiting. It keeps my skin looking and feeling hydrated all day without needing to reapply. The scent is light and clean, nothing strong or overpowering. If your skin is severely dry or cracked, you may need something thicker. For my dryness, this does the job. It’s the one bottle I reach for every day.
