Welcome to Sea Dogs

Sea Dogs is a small business based in Penryn Cornwall, owned and run by Diana Tomlinson with help from her husband John.

Although Di has been working with leather for about 40 years, Sea Dogs as a business has existed only since June 1999, when we were fortunate to find a workshop in an old sail loft next to the Penryn River. Having this workshop has given us the opportunity to expand the business into new areas, but the same care and attention is still given to each project.

Leather Products For Yachts & Boats

Our main activity is in the field of marine leatherwork. The work ranges from chafing patches on yacht rigging and wheel gloves to leather upholstery of entire boat interiors. More >>

One-off Leather Commissions

In addition we produce one-off commissions in leather to clients’ requirements, including non-marine items such as furniture upholstery, cases and bespoke goods. More >>

Cornish Sweaters

We also make a range of traditional Cornish Sweaters (Ganseys) to different village patterns from around Cornwall’s Coastline. More >>

  • Dear Di, many thanks for the beautiful sweater which my husband received recently – he had to collect it from the post office and just couldn’t wait to get there! He is absolutely delighted – it fits perfectly... I’m sure he’ll be back for more!

  • Dear Di, thank you very much for the Isles of Scilly Gansey. My Dad was absolutely delighted with his birthday present. He builds and works horse drawn caravans and always requires such a top.

  • A brief note to let you know how thrilled we are with the new upholstery. The boat looks fantastic, so your advice on the colour and style of leather was well worth seeking. We know it wasn’t a completely straight forward job and so we appreciate the end job all the more!

  • My gansey is proudly worn. It feels a bit like wearing a suit of armour and certainly gives this mouthy politician a thicker skin!
