Jamie at Bill Higham Marine did a great job setting me up with a new Zodiac RIB, trailer and all the extras I was after.

Mark Hind

I first encountered Higham Marine about 9 years ago when having got tired of Honwave transoms rotting out , Zodiac valves being expensive to replace way too frequently when I got sand in there accidentally , and Avons being hellishly overpriced for a leisure boater on a work like budget . Simon Higham had developed the SeaPro HD range to a better spec , using a unique fabric that’s durable but tough and my first Seapro was the 340HD. I live in Cornwall and it’s a little rugged round the coastline and we’re dogged by Pacific Oysters too which have sharp edges to their shells . I’ve had punctures in every inflatable … except my 340 HD . It’s now 9 years old so I’ve just had delivery of a new SeaPro 310HD . Meantime the pontoon in the harbour ate the bow off my grp Dory as the glass fibre is no match for swells against a pontoon and it can be carnage in summer when boaters fight for space to moor up across each others boats . That , right there is the prime situation for needing a better quality boat . Any can be used , but can they survive life in the meantime and for me , 19 years as sailmaker here , yacht racer and student marine scientist, the boat has to be versatile . I’ve towed it to the Solent behind a yacht , I’ve carried divers and their kit for surveys and the sectional aluminium floor hasn’t even dented . I’ve beached it and it’s light enough to roll over and scrub the bottom mid season and this really is a little inflatable that can do big things and not need a trailer or boat lift either . Please folks , don’t mistakenly compare the price to lesser boats , even the assembly works precisely by design ! The upgrade to an all aluminium sectional strengthened transom around 2021 proves Higham Marine listen to us the customer and improved the design so negligence no longer leads to rotting transoms when left full of water for extended periods. Come on people don’t always get it right do we ? I sure don’t , but this range of inflatable boats are the Tonka Toys of the industry. The boat is half the equation. The company. ? I’m in Fowey ( deepest darkest Cornwall ) and I’m happy to give my business to a bunch of great people in Wales ! The reason being they know their products . They care that we get maximum fun for our quid . They go above and beyond to make sure we’re happy to have bought from them , and I’ve dealt with a LOT of boat dealers , owners , fellow yacht racers and owners in my time but won’t shop elsewhere! This week they chatted delivery options with me , confirmed yesterday that my new boat would be delivered today . I woke to messages with tracking details , a courtesy message and Jamie rang me to make sure the pallet line courier had arrived and found me . Come on folks , I’m a 55 year old Luddite afraid of technology and even in this social climate Bill Higham Marines customer support installs confidence in buying online . Thank you all from Simon and Jamie to Aled and the rest of the team . Here’s to getting back on the water and I’ll be seeing you guys again before long …. Psst - heads up folks they don’t only sell boats 😉🤗 Thank you all , Mark

Just purchased my Parsun Long shaft 4stroke, Jamie Williams was very helpful over the phone and obviously very knowledgeable in this field. I had a very slight hiccup on running engine within an hour (My total mistake) I rang Jamie and within 2 minutes my issue was solved, So engine seems very good value for money with 3 years warranty, hopefully runs well over time Would recommend these guys

After buying a new trailer from them and discovering they do repairs and servicing I gave them a try. Friendly, helpful and look like they’ve done a great job, definitely will use again.

Ahoy Bill Higham Marine : Me looking for a Outboard , in the low /mid power range , BUT also using REMOTES , which is essential for my Boat : a Dory , SO WHY DOES BHM NOT prioritise as a choice outboard in the Low /Mid range with REMOTES ? It would make scnse , really would do ! URG These days the BHM is not what it was when in the Midlands , is it ? URG URG
